'''Traditional Chinese medicine''' ('''TCM''') is an [[Medicine:Alternative medicine|alternative medical practice]] drawn from [[Medicine:Traditional medicine|traditional medicine]] in China. It has been described as "fraught with [[Unsolved:Pseudoscience|pseudoscience]]", with the majority of its treatments having no logical [[Chemistry:Mechanism of action|mechanism of action]].<!--This sentence has been extensively discussed, and should not be removed without gaining consensus for the removal on the talkpage first--><ref name="Eigenschink Dearing Dablander et al 2020">{{cite journal |last1=Eigenschink |first1=Michael |last2=Dearing |first2=Lukas |last3=Dablander |first3=Tom E. |last4=Maier |first4=Julian |last5=Sitte |first5=Harald H. |title=A critical examination of the main premises of Traditional Chinese Medicine |journal=Wiener klinische Wochenschrift |date=May 2020 |volume=132 |issue=9–10 |pages=260–273 |doi=10.1007/s00508-020-01625-w |pmid=32198544 |pmc=7253514 }}</ref><ref name="swallow" />

Medicine in traditional China encompassed a range of sometimes competing health and healing practices, folk beliefs, literati theory and [[Philosophy:Confucianism|Confucian philosophy]], [[Unsolved:Chinese herbology|herbal remedies]], [[Unsolved:Chinese food therapy|food]], diet, exercise, medical specializations, and schools of thought.{{sfnb|Andrews|2013b|pp=10-17}} In the early twentieth century, Chinese cultural and political modernizers worked to eliminate traditional practices as backward and unscientific. Traditional practitioners then selected elements of philosophy and practice and organized them into what they called "Chinese medicine" (Chinese: 中医 ''Zhongyi'').{{sfnb|Lei|2014|pp= 97-120}} In the 1950s, the Chinese government sponsored the integration of Chinese and Western medicine,{{sfnb|Taylor|2005|pp=30-36}} and in the Great Proletarian Cultural Revolution of the 1960s, promoted Chinese medicine as inexpensive and popular.<ref name="Gushi 2019" /> After the opening of relations between the United States and China after 1972, there was great interest in the West for what is now called traditional Chinese medicine (TCM).{{sfnb|Taylor|2005|pp=138-141}}

TCM is said to be based on such texts as ''Huangdi Neijing'' (The Inner Canon of the Yellow Emperor),<ref>{{Cite book |url=https://books.google.com/books?id=41JBEAAAQBAJ&dq=Huangdi+Neijing&pg=PR1 |title=Huangdi Neijing: A Synopsis with Commentaries |date=2010-11-03 |publisher=The Chinese University of Hong Kong Press |isbn=978-962-996-927-1 |language=en}}</ref>  and ''[[Chemistry:Compendium of Materia Medica|Compendium of Materia Medica]]'', a sixteenth-century encyclopedic work, and includes various forms of [[Unsolved:Chinese herbology|herbal medicine]], [[Unsolved:Acupuncture|acupuncture]], [[Unsolved:Cupping therapy|cupping therapy]], [[Unsolved:Gua sha|gua sha]], [[Medicine:Tui na|massage (tui na)]], bonesetter (die-da), [[Unsolved:Qigong|exercise (qigong)]], and dietary therapy. TCM is widely used in the [[Place:East Asian cultural sphere|Sinosphere]]. One of the basic tenets is that the body's ''[[Philosophy:Qi|qi]]'' is circulating through channels called [[Medicine:Meridian (Chinese medicine)|meridians]] having branches connected to bodily organs and functions.<ref name="Quackwatch" /> There is no evidence that meridians or vital energy exist. Concepts of the body and of disease used in TCM reflect its ancient origins and its emphasis on dynamic processes over material structure, similar to the humoral theory of [[Medicine:Ancient Greek medicine|ancient Greece]] and ancient Rome.<ref name="Novella2012" />

The demand for traditional medicines in China has been a major generator of illegal wildlife smuggling, linked to the [[Biology:Poaching|killing and smuggling of endangered animals]].<ref>{{Cite news|date=2019-03-28|title=As China pushes traditional medicine globally, illegal wildlife trade flourishes|language=en|work=Reuters|url=https://www.reuters.com/article/us-china-tcm-idUSKCN1R90D5|access-date=2021-10-20}}</ref>

Scholars in the history of medicine in China distinguish its doctrines and practice from those of present-day TCM. As Ian Johnson notes, the term "Traditional Chinese Medicine" was coined by "party propagandists" and first appeared in English in 1955.{{sfnb|Johnson|2021}} [[Biography:Nathan Sivin|Nathan Sivin]] criticizes attempts to treat medicine and medical practices in traditional China as if they were a single system. Instead, he says, there were 2,000 years of "medical system in turmoil" and speaks of a "myth of an unchanging medical tradition."  He urges that "Traditional medicine translated purely into terms of modern medicine becomes partly nonsensical, partly irrelevant, and partly mistaken; that is also true the other way around, a point easily overlooked."{{sfnb|Sivin|1987|p=198}} TJ Hinrichs observes that people in modern Western societies divide healing practices into biomedicine for the body, psychology for the mind, and religion for the spirit, but these distinctions are inadequate to describe medical concepts among Chinese historically and to a considerable degree today.{{sfnb|Hinrichs|2005|p=3859 }}

The medical anthropologist Charles Leslie writes that Chinese, Greco-Arabic, and Indian traditional medicines were all grounded in systems of correspondence that aligned the organization of society, the universe, and the human body and other forms of life into an "all-embracing order of things." Each of these traditional systems was organized with such qualities as heat and cold, wet and dry, light and darkness, qualities that also align the seasons, compass directions, and the human cycle of birth, growth, and death. They provided, Leslie continued, a "comprehensive way of conceiving patterns that ran through all of nature," and  they "served as a classificatory and mnemonic device to observe health problems and to reflect upon, store, and recover empirical knowledge," but they were also "subject to stultifying theoretical elaboration, self-deception, and [[Philosophy:Dogma|dogma]]tism."<ref>{{cite encyclopedia |first= Charles |last= Leslie|article= Medicine |title=Encyclopedia of Asian History |editor-first=Ainslee|editor-last=Embry|volume=  2|pages= 521–522|ref= none}}</ref>

The doctrines of Chinese medicine are rooted in books such as the ''Yellow Emperor's Inner Canon'' and the ''Treatise on Cold Damage'', as well as in cosmological notions such as [[Yin and yang|yin–yang]] and the [[Philosophy:Wuxing (Chinese philosophy)|five phases]]. The "Documentation of Chinese materia medica" (CMM) dates back to around 1,100 BCE when only a few dozen drugs were described. By the end of the 16th century, the number of drugs documented had reached close to 1,900. And by the end of the last century, published records of CMM had reached 12,800 drugs."<ref name="ZxukC">{{cite journal | vauthors = Leung AY | title = Traditional toxicity documentation of Chinese Materia Medica--an overview | journal = Toxicologic Pathology | volume = 34 | issue = 4 | pages = 319–26 | year = 2006 | pmid = 16787890 | doi = 10.1080/01926230600773958 | s2cid = 8301501 | doi-access = free }}</ref> Starting in the 1950s, these precepts were standardized in the People's Republic of China, including attempts to integrate them with modern notions of [[Biology:Anatomy|anatomy]] and [[Biology:Pathology|pathology]].

=== Han dynasty ===
The ''Yellow Emperor's Inner Canon (Huangdi Neijing)'', the oldest received work of Chinese medical theory, was compiled during the Han dynasty around the first century BCE on the basis of shorter texts from different medical lineages.<ref name="Needham 2002" /><ref name="Harper 1998" /><ref name="Sivin 1993">{{Cite book | vauthors = Sivin N |chapter=Huang-ti nei-ching |script-chapter=zh:黃帝內經 |pages=[https://archive.org/details/earlychinesetext00loew/page/n209 196]–215 |title=Early Chinese Texts: A Bibliographical Guide |url=https://archive.org/details/earlychinesetext00loew |url-access=limited |year=1993|publisher=Institute for East Asian Studies, University of California, Berkeley|location=Los Angeles and Berkeley | veditors = Loewe M |isbn = 978-1-55729-043-4}}</ref> Written in the form of dialogues between the legendary Yellow Emperor and his ministers, it offers explanations on the relation between humans, their environment, and the [[Astronomy:Cosmos|cosmos]], on the contents of the body, on human vitality and pathology, on the symptoms of illness, and on how to make diagnostic and therapeutic decisions in light of all these factors.<ref name="Sivin 1993" /> Unlike earlier texts like ''Recipes for Fifty-Two Ailments'', which was excavated in the 1970s from the Mawangdui tomb that had been sealed in 168 BCE, the ''Inner Canon'' rejected the influence of spirits and the use of magic.<ref name="Harper 1998" /> It was also one of the first books in which the cosmological doctrines of Yinyang and the Five Phases were brought to a mature synthesis.<ref name="Sivin 1993" />

The ''Treatise on Cold Damage Disorders and Miscellaneous Illnesses (Shang Han Lun)'' was collated by Zhang Zhongjing sometime between 196 and 220 CE; at the end of the Han dynasty.{{sfnb|Liu|2019}} Focusing on drug prescriptions rather than acupuncture,<ref name="Sivin 1987">{{Cite book | vauthors = Sivin N |title=Traditional Medicine in Contemporary China|year=1987|publisher=Center for Chinese Studies, University of Michigan|location=Ann Arbor |isbn = 978-0-89264-074-4}}</ref><ref name="Ergil 2009">{{Cite book | vauthors = Ergil MC, Ergil KV |url=https://books.google.com/books?id=kdZ1rFKW-LEC |title=Pocket Atlas of Chinese Medicine |year=2009 |publisher=Thieme |location=Stuttgart |isbn=978-3-13-141611-7 |access-date=18 February 2016 |archive-url=https://web.archive.org/web/20170320191445/https://books.google.com/books?id=kdZ1rFKW-LEC |archive-date=20 March 2017 |url-status=live}}</ref> it was the first medical work to combine Yinyang and the Five Phases with drug therapy.<ref name="Unschuld 1985" /> This [[Medicine:Formulary (pharmacy)|formulary]] was also the earliest public Chinese medical text to group symptoms into clinically useful "patterns" (''zheng'' {{lang|zh|證}}) that could serve as targets for therapy.

Nanjing or "Classic of Difficult Issues," originally called "The Yellow Emperor Eighty-one Nan Jing", ascribed to Bian Que in the eastern Han dynasty.

''[[Unsolved:Shennong Ben Cao Jing|Shennong Ben Cao Jing]]'' is one of the earliest written medical books in China. Written during the Eastern Han Dynasty between 200 and 250 CE, it was the combined effort of practitioners in the Qin and Han Dynasties who summarized, collected and compiled the results of pharmacological experience during their time periods.

=== Post-Han dynasty ===
In the centuries that followed, several shorter books tried to summarize or systematize the contents of the  ''Yellow Emperor's Inner Canon''. The ''Canon of Problems'' (probably second century CE) tried to reconcile divergent doctrines from the ''Inner Canon'' and developed a complete medical system centered on needling therapy.<ref name="Sivin 1987" /> The ''AB Canon of Acupuncture and Moxibustion'' (''Zhenjiu jiayi jing'' {{lang|zh|針灸甲乙經}}, compiled by Huangfu Mi sometime between 256 and 282 CE) assembled a consistent body of doctrines concerning acupuncture;<ref name="Sivin 1987" /> whereas the ''Canon of the Pulse'' (''Maijing'' {{lang|zh|脈經}}; c. 280) presented itself as a "comprehensive handbook of diagnostics and therapy."<ref name="Sivin 1987" />

Around 900–1000 AD, Chinese were the first to develop a form of vaccination, known as [[Biology:Variolation|variolation]] or [[Biology:Inoculation|inoculation]], to prevent [[Medicine:Smallpox|smallpox]]. Chinese physicians had realised that when healthy people were exposed to smallpox scab tissue, they had a smaller chance of being infected by the disease later on. The common methods of inoculation at the time was through crushing smallpox scabs into powder and breathing it through the nose.<ref>{{Cite web|last=Bushak|first=Lecia|date=2016-03-21|title=A Brief History Of Vaccines: From Medieval Chinese 'Variolation' To Modern Vaccination|url=https://www.medicaldaily.com/history-vaccines-variolation-378738|access-date=2021-04-16|website=Medical Daily|language=en}}</ref>

Prominent medical scholars of the post-Han period included Tao Hongjing (456–536), Sun Simiao of the Sui and Tang dynasties,  Zhang Jiegu ({{circa|1151}}–1234), and Li Shizhen (1518–1593). <!-- Wu Jian a robber known for being dissected -->

In 1950, Chinese Communist Party (CCP) chairman [[Biography:Mao Zedong|Mao Zedong]] announced support of traditional Chinese medicine, but he did not personally believe in and did not use it.<ref name="Levinovitz 2013" /> In 1952, the president of the Chinese Medical Association said that, "This One Medicine, will possess a basis in modern natural sciences, will have absorbed the ancient and the new, the Chinese and the foreign, all medical achievements—and will be China's New Medicine!"<ref name="Levinovitz 2013">{{cite magazine|url=http://www.slate.com/articles/health_and_science/medical_examiner/2013/10/traditional_chinese_medicine_origins_mao_invented_it_but_didn_t_believe.html|title=Chairman Mao Invented Traditional Chinese Medicine | vauthors = Levinovitz A |magazine=Slate|date=22 October 2013|access-date=7 March 2014|archive-url=https://web.archive.org/web/20140307114753/http://www.slate.com/articles/health_and_science/medical_examiner/2013/10/traditional_chinese_medicine_origins_mao_invented_it_but_didn_t_believe.html|archive-date=7 March 2014|url-status=live}}</ref>

During the Cultural Revolution (1966–1976) the CCP and the government emphasized modernity, cultural identity and China's social and economic reconstruction and contrasted them to the colonial and feudal past. The government established a grassroots health care system as a step in the search for a new national identity and tried to revitalize traditional medicine and made large investments in traditional medicine to try to develop affordable medical care and public health facilities.<ref name="Gushi 2019">{{Cite web|url=https://gushi.tw/chinese-medicine-invented/|script-title=zh:中醫的發明和國族認同有關係？文化大革命對「傳統中醫學」的影響 {{!}} 故事|date=7 April 2019|website=gushi.tw|language=zh-TW|access-date=14 July 2019|title=Gushi.tw|archive-url=https://web.archive.org/web/20190714235827/https://gushi.tw/chinese-medicine-invented/|archive-date=14 July 2019|url-status=live}}</ref> The Ministry of Health directed health care throughout China and established primary care units. Chinese physicians trained in Western medicine were required to learn traditional medicine, while traditional healers received training in modern methods. This strategy aimed to integrate modern medical concepts and methods and revitalize appropriate aspects of traditional medicine. Therefore, traditional Chinese medicine was re-created in response to Western medicine.<ref name="Gushi 2019" />

In 1968, the CCP supported a new system of health care delivery for rural areas. Villages were assigned a [[Medicine:Barefoot doctor|barefoot doctor]] (a medical staff with basic medical skills and knowledge to deal with minor illnesses) responsible for basic medical care. The medical staff combined the values of traditional China with modern methods to provide health and medical care to poor farmers in remote rural areas. The barefoot doctors became a symbol of the Cultural Revolution, for the introduction of modern medicine into villages where traditional Chinese medicine services were used.<ref name="Gushi 2019" />

In the second decade of the twenty-first century, Chinese Communist Party general secretary [[Biography:Xi Jinping|Xi Jinping]] strongly supported TCM, calling it a "gem".

=== Historiography of Chinese medicine ===
Historians have noted two key aspects of Chinese medical history: understanding conceptual differences when translating the term {{lang|zh|身}}, and observing the history from the perspective of [[Astronomy:Cosmology|cosmology]] rather than biology.<ref name="Furth">{{cite book |title=A Flourishing Yin: Gender in China's Medical History, 960–1665 |vauthors=Furth C |date=1999 |publisher=University of California Press |location=Berkeley}}</ref>

In Chinese classical texts, the term {{lang|zh|身}} is the closest historical translation to the English word "body" because it sometimes refers to the physical human body in terms of being weighed or measured, but the term is to be understood as an "ensemble of functions" encompassing both the human psyche and emotions. This concept of the human body is opposed to the European duality of a separate mind and body.<ref name="Furth" /> It is critical for scholars to understand the fundamental differences in concepts of the body in order to connect the medical theory of the classics to the "human organism" it is explaining.<ref name="Furth" />{{rp|20}}

Chinese scholars established a correlation between the cosmos and the "human organism." The basic components of cosmology, qi, yin yang and the Five Phase theory, were used to explain health and disease in texts such as ''Huangdi neijing''.<ref name="Furth" /> [[Yin and yang]] are the changing factors in cosmology, with ''[[Philosophy:Qi|qi]]'' as the vital force or energy of life. The Five Phase theory (''[[Philosophy:Wuxing (Chinese philosophy)|Wuxing]]'') of the Han dynasty contains the elements wood, fire, earth, metal, and water. By understanding medicine from a cosmology perspective, historians better understand Chinese medical and social classifications such as gender, which was defined by a domination or remission of yang in terms of yin.

These two distinctions are imperative when analyzing the history of traditional Chinese medical science.

A majority of Chinese medical history written after the classical canons comes in the form of primary source case studies where academic physicians record the illness of a particular person and the healing techniques used, as well as their effectiveness.<ref name="Furth" /> Historians have noted that Chinese scholars wrote these studies instead of "books of prescriptions or advice manuals;" in their historical and environmental understanding, no two illnesses were alike so the healing strategies of the practitioner was unique every time to the specific diagnosis of the patient.<ref name="Furth" /> Medical case studies existed throughout Chinese history, but "individually authored and published case history" was a prominent creation of the Ming dynasty.<ref name="Furth" /> An example such case studies would be the literati physician, Cheng Congzhou, collection of 93 cases published in 1644.<ref name="Furth" />

==Critique==
[[History:History of science|Historians of science]] have developed the study of medicine in traditional China into a field with its own scholarly associations, journals, graduate programs, and debates with each other.{{sfnb|Sivin|1988}}  Many distinguish "medicine in traditional China" from the recent Traditional Chinese Medicine (TCM), which took elements from traditional texts and practices to construct a systematic body. Paul Unschuld, for instance, sees a "departure of TCM from its historical origins." {{sfnb|Unschuld|2018|p=xi}} What is called "Traditional Chinese Medicine" and practiced today in China and the West is not thousands of years old, but recently constructed using selected traditional terms, some of which have been taken out of context, some badly misunderstood. He has criticized Chinese and Western popular books for [[Cherry picking|selective use of evidence]], choosing only those works or parts of historical works that seem to lead to modern medicine, ignoring those elements that do not now seem to be effective.{{sfnb|Unschuld|1988|p=647}}

A 2007 editorial the journal ''Nature'' wrote that TCM "remains poorly researched and supported, and most of its treatments have no logical [[Chemistry:Mechanism of action|mechanism of action]]."<ref name="swallow" /><ref name="Shang-2007" /> Critics say that TCM theory and practice have no basis in modern science, and TCM practitioners do not agree on what diagnosis and treatments should be used for any given person.<ref name="Quackwatch" /> A ''Nature'' editorial described TCM as "fraught with [[Unsolved:Pseudoscience|pseudoscience]]".<ref name="swallow" />   A review of the literature in 2008 found that scientists are "still unable to find a shred of evidence" according to standards of science-based medicine for traditional Chinese concepts such as ''qi'', meridians, and acupuncture points,<ref name="bIPgX">{{harvnb|Singh & Ernst|2008|page = 72}}</ref> and that the traditional principles of acupuncture are deeply flawed.<ref name="FJS08">{{harvnb|Singh & Ernst|2008|page = 107}}</ref> "Acupuncture points and meridians are not a reality", the review continued, but "merely the product of an ancient Chinese philosophy".<ref name="5y6YH">{{harvnb|Singh & Ernst|2008|page= 387}}</ref> In June 2019, the [[Organization:World Health Organization|World Health Organization]] included traditional Chinese medicine in a global diagnostic compendium, but a spokesman said this was "not an endorsement of the scientific validity of any Traditional Medicine practice or the efficacy of any Traditional Medicine intervention."<ref>{{cite journal |title=The World Health Organization's decision about traditional Chinese medicine could backfire |journal=Nature |date=5 June 2019 |volume=570 |issue=7759 |pages=5 |doi=10.1038/d41586-019-01726-1 |pmid=31165792 |bibcode=2019Natur.570Q...5. |s2cid=174809790 |doi-access=free }}</ref><ref>{{Cite web |url=https://www.scientificamerican.com/article/the-world-health-organization-gives-the-nod-to-traditional-chinese-medicine-bad-idea/ |title=The World Health Organization Gives the Nod to Traditional Chinese Medicine.

A 2012 review of cost-effectiveness research for TCM found that studies had low [[Levels of evidence|levels of evidence]], with no beneficial outcomes.<ref name="Zhang2012" /> Pharmaceutical research on the potential for creating new drugs from traditional remedies has few successful results.<ref name="swallow" /> Proponents suggest that research has so far missed key features of the art of TCM, such as unknown interactions between various ingredients and complex interactive biological systems.<ref name="swallow" /> One of the basic tenets of TCM is that the body's ''[[Philosophy:Qi|qi]]'' (sometimes translated as vital energy) is circulating through channels called [[Medicine:Meridian (Chinese medicine)|meridians]] having branches connected to bodily organs and functions.<ref name="Quackwatch" /> The concept of vital energy is pseudoscientific. Concepts of the body and of disease used in TCM reflect its ancient origins and its emphasis on dynamic processes over material structure, similar to [[History:Classical antiquity|Classical]] humoral theory.<ref name="Novella2012" />

TCM has also been controversial within China. In 2006, the Chinese philosopher Zhang Gongyao triggered a national debate with an article entitled "Farewell to Traditional Chinese Medicine", arguing that TCM was a pseudoscience that should be abolished in public healthcare and academia. The Chinese government however, took the stance that TCM is a science and continued to encourage its development.<ref name="qiu">{{cite journal | vauthors = Qiu J | title = China plans to modernize traditional medicine | journal = Nature | volume = 446 | issue = 7136 | pages = 590–1 | date = April 2007 | pmid = 17410143 | doi = 10.1038/446590a | quote = Zhang argued that TCM is a pseudoscience and should not be part of public healthcare and research | doi-access = free | bibcode = 2007Natur.446..590Q }}</ref>

==Philosophical background==
Traditional Chinese medicine (TCM) is a broad range of medicine practices sharing common concepts which have been developed in China and are based on a tradition of more than 2,000 years, including various forms of [[Unsolved:Chinese herbology|herbal medicine]], acupuncture, massage ({{lang|zh-Latn|tui na}}), exercise ({{lang|zh-Latn|qigong}}), and dietary therapy.<ref name="TCMNCCIH">Traditional Chinese Medicine, National Center for Complementary and Integrative Health, [http://nccih.nih.gov/health/whatiscam/chinesemed.htm Traditional Chinese Medicine: An Introduction] {{Webarchive|url=https://web.archive.org/web/20150626223845/https://nccih.nih.gov/health/whatiscam/chinesemed.htm |date=26 June 2015}}</ref><ref name="uOuvz">{{cite journal | vauthors = Bannon D |title=Balancing the Yang and Yin: Development and Contributions of Chinese Medicine |journal=Asian Pacific Quarterly |volume=26 |issue=2 |year=1994 |pages=22–37}}</ref> It is primarily used as a complementary alternative medicine approach.<ref name="TCMNCCIH" /> TCM is widely used in China and it is also used in the West.<ref name="TCMNCCIH" /> Its philosophy is based on Yinyangism (i.e., the combination of Five Phases theory with Yin–Yang theory),<ref name="Zou Yan">{{cite encyclopedia|url=http://www.britannica.com/EBchecked/topic/607826/Zou-Yan|title=Zou Yan|encyclopedia=Encyclopædia Britannica|access-date=1 March 2011|archive-url=https://web.archive.org/web/20150426150251/http://www.britannica.com/EBchecked/topic/607826/Zou-Yan|archive-date=26 April 2015|url-status=live}}</ref> which was later absorbed by Daoism.<ref name="IiZhf">Liu, Zheng-Cai (1999): [https://books.google.com/books?id=UNUiHP7MPJMC&pg=PA39 "A Study of Daoist Acupuncture & Moxibustion"] {{Webarchive|url=https://web.archive.org/web/20220715132347/https://books.google.com/books?id=UNUiHP7MPJMC&pg=PA39 |date=15 July 2022 }} Blue Poppy Press, first edition. {{ISBN|978-1-891845-08-6}}</ref> Philosophical texts influenced TCM, mostly by being grounded in the same theories of ''qi'', ''yin-yang'' and ''wuxing'' and microcosm-macrocosm analogies.<ref name="629O1">{{Citation| vauthors = Raphals L |title=Chinese Philosophy and Chinese Medicine|year=2017|url=https://plato.stanford.edu/archives/fall2017/entries/chinese-phil-medicine/|encyclopedia=The Stanford Encyclopedia of Philosophy| veditors = Zalta EN |edition=Fall 2017|publisher=Metaphysics Research Lab, Stanford University|access-date=17 January 2020 |archive-url= https://web.archive.org/web/20190318040920/https://plato.stanford.edu/archives/fall2017/entries/chinese-phil-medicine/|archive-date=18 March 2019 |url-status=live}}</ref>
[[File:Yin yang.svg|thumb|right|200px|Yin and yang symbol for balance. In traditional Chinese Medicine, good health is believed to be achieved by various balances, including a balance between yin and yang.]]

===Yin and yang===
{{Main|Yin and yang}}

Yin and yang are ancient Chinese deductive reasoning concepts used within Chinese medical diagnosis which can be traced back to the Shang dynasty<ref name="Men 2010">Men, J. & Guo, L. (2010) [https://books.google.com/books?id=KxoVAXt09F8C&q=tcm+yin+yang&pg=PA60 "A General Introduction to Traditional Chinese Medicine"] {{Webarchive|url=https://web.archive.org/web/20170320171929/https://books.google.com/books?id=KxoVAXt09F8C&pg=PA60&dq=tcm+yin+yang&hl=zh-CN#v=onepage&q=tcm%20yin%20yang&f=false |date=20 March 2017}} Science Press. {{ISBN|978-1-4200-9173-1}}</ref> (1600–1100&nbsp;BCE). They represent two abstract and complementary aspects that every phenomenon in the universe can be divided into.<ref name="Men 2010" /> Primordial analogies for these aspects are the sun-facing (yang) and the shady (yin) side of a hill.<ref name="Ergil 2009" /> Two other commonly used representational allegories of yin and yang are water and fire.<ref name="Men 2010" /> In the [[Yin and yang|yin–yang theory]], detailed attributions are made regarding the yin or yang character of things:

The concept of yin and yang is also applicable to the human body; for example, the upper part of the body and the back are assigned to yang, while the lower part of the body is believed to have the yin character.<ref name="Wiseman 1996" /> Yin and yang characterization also extends to the various body functions, and – more importantly – to disease symptoms (e.g., cold and heat sensations are assumed to be yin and yang symptoms, respectively).<ref name="Wiseman 1996">{{harvp|Wiseman|Ellis|1996}}{{page needed|date=October 2019}}</ref> Thus, yin and yang of the body are seen as phenomena whose lack (or over-abundance) comes with characteristic symptom combinations:

* Yang vacuity ("vacuity-cold"): aversion to cold, cold limbs, bright white complexion, long voidings of clear urine, diarrhea, pale and enlarged tongue, and a slightly weak, slow and fine pulse.<ref name="Wiseman 1996" />

TCM also identifies drugs believed to treat these specific symptom combinations, i.e., to reinforce yin and yang.<ref name="Ergil 2009" />

==Model of the body==

[[File:ChineseMedecine.JPG|thumb|right|200px|Old Chinese medical chart on acupuncture meridians]]

TCM "holds that the body's vital energy (''chi'' or ''qi'') circulates through channels, called ''[[Medicine:Meridian (Chinese medicine)|meridians]]'', that have branches connected to bodily organs and functions."<ref name="Quackwatch" /> Its view of the human body is only marginally concerned with anatomical structures, but focuses primarily on the body's ''functions''<ref name="Matuk 2006"/><ref name="Ross 1984" /> (such as digestion, breathing, temperature maintenance, etc.):

These functions are aggregated and then associated with a primary functional entity – for instance, nourishment of the tissues and maintenance of their moisture are seen as connected functions, and the entity postulated to be responsible for these functions is xiě (blood).<ref name="Ross 1984" /> These functional entities thus constitute ''concepts'' rather than something with biochemical or anatomical properties.<ref name="HxfYB">Ross, Jeremy (1984).

===''Qi''===
{{Main|Qi}}

''Qi'' is a [[Philosophy:Polysemy|polysemous]] word that Traditional Chinese medicine distinguishes as being able to transform into many different qualities of ''qi'' ({{lang-zh|s=气 |t=氣 |p=qì |labels=no}}).<ref name="Aung & Chen" /> In a general sense, ''qi'' is something that is defined by five "cardinal functions":<ref name="Aung & Chen">{{harvp|Aung|Chen|2007|pp=11–12}}. "{{lang|zh|氣的生理功能...(一)推動作用...(二)溫煦作用...(三)防御作用...(四)固攝作用...(五)氣化作用}}" &#91;Physiological functions of qi: 1.) Function of actuation ... 2.) Function of warming ... 3.) Function of defense ... 4.) Function of containment ... 5.) Function of transformation ...&#93;</ref>
# Actuation ({{lang-zh|t=推動 |s=推动 |p=tuīdòng |labels=no}}) – of all physical processes in the body, especially the circulation of all body fluids such as blood in their vessels. This includes actuation of the functions of the zang-fu organs and meridians.
# Warming ({{lang-zh|t=溫煦 |s=温煦 |p=wēnxù |labels=no}}) – the body, especially the limbs.
# Defense ({{lang-zh|c=防御 |p=fángyù |labels=no}}) – against Exogenous Pathogenic Factors
# Containment ({{lang-zh|t=固攝 |s=固摄 |p=gùshè |labels=no}}) – of body fluids, i.e., keeping blood, sweat, urine, semen, etc. from leakage or excessive emission.
# Inter-transformationel ({{lang-zh|t=氣化 |s=气化 |p=qìhuà |labels=no}}) – of food, drink, and breath into ''qi'', xue (blood), and jinye ("fluids"), and/or transformation of all of the latter into each other.
A lack of ''qi'' will be characterized especially by pale complexion, lassitude of spirit, lack of strength, spontaneous sweating, laziness to speak, non-digestion of food, shortness of breath (especially on exertion), and a pale and enlarged tongue.<ref name="Wiseman 1996" />

''Qi'' is believed to be partially generated from food and drink, and partially from air (by breathing). Another considerable part of it is inherited from the parents and will be consumed in the course of life.

TCM uses special terms for ''qi'' running inside of the blood vessels and for qi that is distributed in the skin, muscles, and tissues between them. The former is called ''yingqi'' ({{lang-zh|s=营气 |t=營氣 |p=yíngqì |labels=no}}); its function is to complement xuè and its nature has a strong yin aspect (although ''qi'' in general is considered to be yang).<ref name="Elizabeth Reninger">{{cite web |url=http://taoism.about.com/od/qi/a/Qi_Forms.htm |title=Qi (Chi): Various Forms Used in Qigong & Chinese Medicine – How Are The Major Forms Of Qi Created Within The Body? | vauthors = Reninger E |access-date=6 December 2010 |archive-url=https://web.archive.org/web/20110707075119/http://taoism.about.com/od/qi/a/Qi_Forms.htm |archive-date=7 July 2011 |url-status=live}}</ref> The latter is called ''weiqi'' ({{lang-zh|t=衛氣 |s=卫气 |p=weìqì |labels=no}}); its main function is defence and it has pronounced yang nature.<ref name="Elizabeth Reninger" />

''Qi'' is said to circulate in the meridians. Just as the ''qi'' held by each of the zang-fu organs, this is considered to be part of the 'principal' ''qi'' of the body.{{efn|{{lang-zh|t=元氣 |s=元气 |p=yuánqì |labels=no}}, also known as "true" ''qi'' ({{lang-zh|t=真氣 |s=真气 |p=zhēnqì |labels=no}}) or "original" ''qi'' ({{lang-zh|t=原氣 |s=原气 |p=yuánqì |labels=no}}).}}

===Xie===
In contrast to the majority of other functional entities, {{transliteration|zh|xuè}} or {{transliteration|zh|xiě}} ({{lang|zh|血}}, "blood") is correlated with a physical form – the red liquid running in the blood vessels.<ref name="Blood from a TCM Perspective">{{cite web|url=http://www.shen-nong.com/eng/principles/blood.html|title=Blood from a TCM Perspective|publisher=Shen-Nong Limited|access-date=4 April 2011|archive-url=https://web.archive.org/web/20110716053655/http://www.shen-nong.com/eng/principles/blood.html|archive-date=16 July 2011|url-status=live}}</ref> Its concept is, nevertheless, defined by its functions: nourishing all parts and tissues of the body, safeguarding an adequate degree of moisture, and sustaining and soothing both consciousness and sleep.<ref name="Blood from a TCM Perspective" />

Typical symptoms of a lack of {{transliteration|zh|xiě}} (usually termed "blood vacuity" &#91;{{zh|c=血虚 |p=xiě xū|labels=no}}&#93;) are described as: Pale-white or withered-yellow complexion, dizziness, flowery vision, palpitations, insomnia, numbness of the extremities; pale tongue; "fine" pulse.<ref name="cudGr">{{harvp|Wiseman|Ellis|1996|p=147}}</ref>

===''Jinye''===
Closely related to xuě are the ''jinye'' ({{lang-zh|c=津液 |p=jīnyè |labels=no}}, usually translated as "body fluids"), and just like xuě they are considered to be yin in nature, and defined first and foremost by the functions of nurturing and moisturizing the different structures of the body.<ref name="sacredlotus">{{cite web |url=http://www.sacredlotus.com/theory/substances/jinye.cfm |title=Body Fluids (Yin Ye) |publisher=2001–2010 by Sacred Lotus Arts |access-date=9 December 2010 |archive-url=https://web.archive.org/web/20101127132141/http://sacredlotus.com/theory/substances/jinye.cfm |archive-date=27 November 2010 |url-status=live}}</ref> Their other functions are to harmonize yin and yang, and to help with the secretion of waste products.<ref name="NJxjg">"{{lang|zh|三、津液的功能 ...（三）调节阴阳 ...（四）排泄废物 ..."}} &#91;3.)

''Jinye'' are ultimately extracted from food and drink, and constitute the raw material for the production of xuě; conversely, xuě can also be transformed into ''jinye''.<ref name="sacredlotus" /> Their palpable manifestations are all bodily fluids: [[Biology:Tears|tears]], sputum, saliva, [[Biology:Gastric acid|gastric acid]], [[Biology:Synovial fluid|joint fluid]], [[Medicine:Perspiration|sweat]], [[Biology:Urine|urine]], etc.<ref name="XOqR0">"{{lang|zh|津液包括各脏腑组织的正常体液和正常的分泌物，胃液、肠液、唾液、关节液等。习惯上也包括代谢产物中的尿、汗、泪等。}}" [The (term) ''jinye'' comprises all physiological bodily fluids of the zang-fu and tissues, and physiological secretions, gastric juice, intestinal juice, saliva, joint fluid, etc. Customarily, this also includes metabolic products like urine, sweat, tears, etc.] As seen at: {{cite web |url=http://www.zysj.com.cn/lilunshuji/jichulilun/44-4-4.html |script-title=zh:《中医基础理论》第四章 精、气、血、津液. 第四节 津液 |access-date=9 December 2010 |language=zh |trans-title=Basics of TCM theory.

===''Zangfu''===
The ''zangfu'' ({{lang-zh|s=脏腑 |t=臟腑 |p=zàngfǔ |labels=no}}) are the collective name of eleven entities (similar to organs) that constitute the centre piece of TCM's systematization of bodily functions. The term ''zang'' refers to the five considered to be yin in nature—[[Medicine:Heart (Chinese medicine)|Heart]], Liver, Spleen, [[Medicine:Lung (Chinese medicine)|Lung]], Kidney—while ''fu'' refers to the six associated with yang—Small Intestine, Large Intestine, Gallbladder, Urinary Bladder, Stomach and San Jiao.<ref name="mUWDG">by citation from the Huangdi Neijing's Suwen: "{{lang|zh|言人身臟腑中陰陽，則臟者為陰，腑者為陽。}}" &#91;Within the human body's zang-fu, there's yin and yang; the zang are yin, the fu are yang&#93;.

Since their concept was developed on the basis of Wǔ Xíng philosophy, each zàng is paired with a fǔ, and each zàng-fǔ pair is assigned to one of five elemental qualities (i.e., the Five Elements or Five Phases).<ref name="K2pRO">{{harvp|Aung|Chen|2007|pp= 15–16}}</ref> These correspondences are stipulated as:
* Fire ({{lang|zh|火}}) = Heart ({{zh|c=心|labels=no|p=xīn}}) and Small Intestine ({{zh|c=小腸|labels=no|p=xiaǒcháng}}) (and, secondarily, Sānjiaō &#91;{{lang|zh|三焦}}, "Triple Burner"&#93; and Pericardium [{{zh|c=心包|p=xīnbaò|labels=no}}])

* Water ({{lang|zh|水}}) = Kidney ({{zh|c=腎 |labels=no|p=shèn}}) and Bladder ({{zh|c=膀胱|labels=no|p=pángguāng}})
* Wood ({{lang|zh|木}}) = Liver ({{zh|c=肝 |labels=no|p=gān}}) and Gallbladder ({{zh|c=膽|labels=no|p=dān}})

The zàng-fǔ are also connected to the [[Medicine:Meridian (Chinese medicine)#12 standard meridians|twelve standard meridians]] – each yang meridian is attached to a fǔ organ, and five of the yin meridians are attached to a zàng.<ref name="4IoBNy" /> As there are only five zàng but six yin meridians, the sixth is assigned to the Pericardium, a peculiar entity almost similar to the Heart zàng.<ref name="4IoBNy">{{harvp|Aung|Chen|2007|p=16}}</ref>

== Gender in traditional medicine ==
''Fuke'' ({{lang-zh|t=婦科 |s=妇科 |p=Fùkē |labels=no}}) is the traditional Chinese term for women's medicine (it means gynecology and [[Medicine:Obstetrics|obstetrics]] in modern medicine). However, there are few or no ancient works on it except for Fu Qingzhu's ''Fu Qingzhu Nu Ke'' (Fu Qingzhu's ''Gynecology'').<ref name="PyYtM">{{Cite book|title=Fu Qingzhu's gynecology| vauthors = Fu S |date=1995 |publisher=Blue Poppy Press|isbn=093618535X|oclc=46812372}}</ref> In traditional China, as in many other cultures, the health and medicine of female bodies was less understood than that of male bodies.

In clinical encounters, women and men were treated differently. Diagnosing women was not as simple as diagnosing men. First, when a woman fell ill, an appropriate adult man was to call the doctor and remain present during the examination, for the woman could not be left alone with the doctor.<ref name="nzFZzH">{{Cite book|title=A flourishing yin: gender in Chinaʼs medical history| vauthors = Furth C |publisher=University of California Press|year=1999|isbn=0520208293|pages=245, 250, 255|oclc=955120174}}</ref> The physician would discuss the female's problems and diagnosis only through the male. However, in certain cases, when a woman dealt with complications of pregnancy or birth, older women assumed the role of the formal authority. Men in these situations would not have much power to interfere.<ref name="54E8O5" />  Second, women were often silent about their issues with doctors due to the societal expectation of female modesty when a male figure was in the room.<ref name="nzFZzH" /> Third, patriarchal society also caused doctors to call women and children patients "the anonymous category of family members (''Jia Ren'') or household (''Ju Jia'')"<ref name="nzFZzH" /> in their journals. This anonymity and lack of conversation between the doctor and woman patient led to the inquiry diagnosis of the Four Diagnostic Methods<ref name="jBODo">{{Cite book|title=Diagnostic of Traditional Chinese Medicine – A newly compiled practical English-Chinese library of Traditional Chinese medicine| vauthors = Wang LF |publisher=Shanghai university of TCM press|year=2002|isbn=7810106805}}</ref> being the most challenging. Doctors used a medical doll known as a Doctor's lady, on which female patients could indicate the location of their symptoms.<ref name="Byouo">{{cite book | url=https://books.google.com/books?id=xtgVBAAAQBAJ&pg=PA66 | title=You and Your Doctor: A Guide to a Healing Relationship, with Physicians' Insights | publisher=McFarland & Company | vauthors = Heller T | year=2012 | pages=66| isbn=9780786462933}}</ref>

Cheng Maoxian (b. 1581), who practiced medicine in Yangzhou, described the difficulties doctors had with the norm of female modesty. One of his case studies was that of Fan Jisuo's teenage daughter, who could not be diagnosed because she was unwilling to speak about her symptoms, since the illness involved discharge from her intimate areas.<ref name="54E8O5">{{cite book|title=A Flourishing Yin: Gender in China's Medical History| vauthors = Furth C |date=March 1999| publisher = University of California Press |isbn=9780520208292}}</ref> As Cheng describes, there were four standard methods of diagnosis – looking, asking, listening and smelling and touching (for pulse-taking). To maintain some form of modesty, women would often stay hidden behind curtains and screens. The doctor was allowed to touch enough of her body to complete his examination, often just the pulse taking. This would lead to situations where the symptoms and the doctor's diagnosis did not agree and the doctor would have to ask to view more of the patient.<ref name="VtvP4C">{{cite book|title=A Flourishing Yin: Gender in China's Medical History: 960–1665| vauthors = Furth C |date=March 1999|isbn=9780520208292|page=248| publisher = University of California Press }}</ref>

These social and cultural beliefs were often barriers to learning more about female health, with women themselves often being the most formidable barrier. Women were often uncomfortable talking about their illnesses, especially in front of the male chaperones that attended medical examinations.<ref name="yzdrXFB" /> Women would choose to omit certain symptoms as a means of upholding their chastity and honor. One such example is the case in which a teenage girl was unable to be diagnosed because she failed to mention her symptom of vaginal discharge.<ref name="yzdrXFB" /> Silence was their way of maintaining control in these situations, but it often came at the expense of their health and the advancement of female health and medicine. This silence and control were most obviously seen when the health problem was related to the core of Ming ''fuke'', or the sexual body.<ref name="yzdrXFB" /> It was often in these diagnostic settings that women would choose silence. In addition, there would be a conflict between patient and doctor on the probability of her diagnosis. For example, a woman who thought herself to be past the point of child-bearing age, might not believe a doctor who diagnoses her as pregnant.<ref name="yzdrXFB" /> This only resulted in more conflict.

According to ''Bequeathed Writings of Master Chu'' the male's yang pulse movement follows an ascending path in "compliance [with cosmic direction] so that the cycle of circulation in the body and the Vital Gate are felt...The female's yin pulse movement follows a defending path against the direction of cosmic influences, so that the nadir and the Gate of Life are felt at the inch position of the left hand".<ref name="Z7q7v">{{Cite book|title=Bequeathed Writings of Master Chu}}</ref> In sum, classical medicine marked yin and yang as high and low on bodies which in turn would be labeled normal or abnormal and gendered either male or female.<ref name="54E8O5" />

Bodily functions could be categorized through systems, not organs. In many drawings and diagrams, the twelve channels and their visceral systems were organized by yin and yang, an organization that was identical in female and male bodies. Female and male bodies were no different on the plane of yin and yang. Their gendered differences were not acknowledged in diagrams of the human body. Medical texts such as the ''Yuzuan yizong jinjian'' were filled with illustrations of male bodies or androgynous bodies that did not display gendered characteristics.<ref name="dsK5E">Wu, Yi-Li, and {{lang|zh|吳一立}}.

As in other cultures, fertility and menstruation dominate female health concerns.<ref name="yzdrXFB" />  Since male and female bodies were governed by the same forces, traditional Chinese medicine did not recognize the womb as the place of reproduction. The abdominal cavity presented pathologies that were similar in both men and women, which included tumors, growths, hernias, and swellings of the genitals. The "master system," as Charlotte Furth calls it, is the kidney visceral system, which governed reproductive functions. Therefore, it was not the anatomical structures that allowed for pregnancy, but the difference in processes that allowed for the condition of pregnancy to occur.<ref name="yzdrXFB" />

=== Pregnancy ===
Traditional Chinese medicine's dealings with pregnancy are documented from at least the seventeenth century. According to Charlotte Furth, "a pregnancy (in the seventeenth century) as a known bodily experience emerged [...] out of the liminality of menstrual irregularity, as uneasy digestion, and a sense of fullness".<ref name="nzFZzH" /> These symptoms were common among other illness as well, so the diagnosis of pregnancy often came late in the term. The ''Canon of the Pulse'', which described the use of pulse in diagnosis, stated that pregnancy was "a condition marked by symptoms of the disorder in one whose pulse is normal" or "where the pulse and symptoms do not agree".<ref name="BddYV">{{Citation|chapter=Diagnosis for Pulse-Taking and Pulse Subtlety|date=March 2019|pages=69–77|publisher=WORLD SCIENTIFIC|isbn=9789813273573|doi=10.1142/9789813273580_0017|title=The Yellow Emperor's Classic of Medicine – Essential Questions|s2cid=241372790}}</ref> Women were often silent about suspected pregnancy, which led to many men not knowing that their wife or daughter was pregnant until complications arrived. Complications through the misdiagnosis and the woman's reluctance to speak often led to medically induced abortions. Cheng, Furth wrote, "was unapologetic about endangering a fetus when pregnancy risked a mother's well being".<ref name="nzFZzH" /> The method of abortion was the ingestion of certain herbs and foods. Disappointment at the loss of the fetus often led to family discord.<ref name="nzFZzH" />

=== Postpartum ===
If the baby and mother survived the term of the pregnancy, childbirth was then the next step. The tools provided for birth were: towels to catch the blood, a container for the placenta, a pregnancy sash to support the belly, and an infant swaddling wrap.<ref name="BTqQT">{{Cite book|title=Shinzoku kibun.| vauthors = Nakagawa T, Sun B, Muramatsu K |publisher=Tōkyō: Heibonsha.|year=1966}}</ref> With these tools, the baby was born, cleaned, and swaddled; however, the mother was then immediately the focus of the doctor to replenish her ''qi''.<ref name="nzFZzH" /> In his writings, Cheng places a large amount of emphasis on the Four Diagnostic methods to deal with postpartum issues and instructs all physicians to "not neglect any [of the four methods]".<ref name="nzFZzH" /> The process of birthing was thought to deplete a woman's blood level and ''qi'' so the most common treatments for postpartum were food (commonly garlic and ginseng), medicine, and rest.<ref name="QDRbHW">Cheng Maoxian. ''Yi'an'' (casebook). Dated 1633, but Xue Qinghu (1991) states that the original was printed in 1644</ref> This process was followed up by a month check-in with the physician, a practice known as ''zuo yuezi''.<ref name="aeNQF">{{cite journal |last1=Pillsbury |first1=Barbara L.K. |title='Doing the month': Confinement and convalescence of Chinese women after childbirth |journal=Social Science & Medicine. Part B: Medical Anthropology |date=January 1978 |volume=12 |issue=1B |pages=11–22 |doi=10.1016/0160-7987(78)90003-0 |pmid=565536 |s2cid=13414474 }}</ref>

=== Infertility ===
Infertility, not very well understood, posed serious social and cultural repercussions. The seventh-century scholar Sun Simiao is often quoted: "those who have prescriptions for women's distinctiveness take their differences of pregnancy, childbirth and [internal] bursting injuries as their basis."<ref name="uHbrTu" /> Even in contemporary ''fuke'' placing emphasis on reproductive functions, rather than the entire health of the woman, suggests that the main function of ''fuke'' is to produce children.

Once again, the kidney visceral system governs the "source ''Qi''", which governs the reproductive systems in both sexes. This source ''Qi'' was thought to "be slowly depleted through sexual activity, menstruation and childbirth."<ref name="uHbrTu" /> It was also understood that the depletion of source Qi could result from the movement of an external pathology that moved through the outer visceral systems before causing more permanent damage to the home of source Qi, the kidney system. In addition, the view that only very serious ailments ended in the damage of this system means that those who had trouble with their reproductive systems or fertility were seriously ill.

According to traditional Chinese medical texts, infertility can be summarized into different syndrome types. These were spleen and kidney depletion (yang depletion), liver and kidney depletion (yin depletion), blood depletion, phlegm damp, liver oppression, and damp heat. This is important because, while most other issues were complex in Chinese medical physiology, women's fertility issues were simple. Most syndrome types revolved around menstruation, or lack thereof. The patient was entrusted with recording not only the frequency, but also the "volume, color, consistency, and odor of menstrual flow."<ref name="uHbrTu" /> This placed responsibility of symptom recording on the patient, and was compounded by the earlier discussed issue of female chastity and honor. This meant that diagnosing female infertility was difficult, because the only symptoms that were recorded and monitored by the physician were the pulse and color of the tongue.<ref name="uHbrTu" />

== Concept of disease ==
In general, disease is perceived as a disharmony (or imbalance) in the functions or interactions of yin, yang, qi, xuĕ, zàng-fǔ, meridians etc. and/or of the interaction between the human body and the environment.<ref name="Wiseman 1996" /> Therapy is based on which "pattern of disharmony" can be identified.<ref name="Ergil 2009" /><ref name="Flaws 1996" /> Thus, "pattern discrimination" is the most important step in TCM diagnosis.<ref name="Ergil 2009" /><ref name="Flaws 1996" /> It is also known to be the most difficult aspect of practicing TCM.<ref name="Flaws 1990" />

To determine which pattern is at hand, practitioners will examine things like the color and shape of the tongue, the relative strength of pulse-points, the smell of the breath, the quality of breathing or the sound of the voice.<ref name="xhEsP">"Tongue Diagnosis in Chinese Medicine", Giovanni Maciocia, Eastland Press; Revised edition (June 1995)</ref><ref name="Maciocia">{{Cite book | vauthors = Maciocia G |title=The Foundations of Chinese Medicine|publisher=Churchill Livingstone|year=1989}}</ref> For example, depending on tongue and pulse conditions, a TCM practitioner might diagnose bleeding from the mouth and nose as: "Liver fire rushes upwards and scorches the Lung, injuring the blood vessels and giving rise to reckless pouring of blood from the mouth and nose."<ref name="Deadman">{{cite journal |last1=Deadman |first1=Peter |last2=Al-Khafaji |first2=Mazin |title=Some Acupuncture Points Which Treat Disorders of Blood |journal=Journal of Chinese Medicine |date=September 1994 |issue=46 |pages=21–29 |url=https://www.journalofchinesemedicine.com/some-acupuncture-points-which-treat-disorders-of-blood.html }}</ref> He might then go on to prescribe treatments designed to clear heat or supplement the Lung.

===Disease entities===
In TCM, a disease has two aspects: "bìng" and "zhèng".<ref name="Clavey 1995">Clavey, Steven (1995): [https://books.google.com/books?id=2RQMLGcFe6kC&q=tcm+ba+gang+diagnosis&pg=PR30 "Fluid physiology and pathology in traditional Chinese medicine"]. Elsevier. 2nd edition, 2003. {{ISBN|978-0-443-07194-2}}</ref> The former is often translated as "disease entity",<ref name="Ergil 2009" /> "disease category",<ref name="Flaws 1990" /> "illness",<ref name="Clavey 1995" /> or simply "diagnosis".<ref name="Clavey 1995" /> The latter, and more important one, is usually translated as "pattern"<ref name="Ergil 2009" /><ref name="Flaws 1990" /> (or sometimes also as "syndrome"<ref name="Clavey 1995" />). For example, the disease entity of a common cold might present with a pattern of wind-cold in one person, and with the pattern of wind-heat in another.<ref name="Ergil 2009" />

From a scientific point of view, most of the disease entities ({{zh|c=病|labels=no|p=bìng}}) listed by TCM constitute symptoms.<ref name="Ergil 2009" /> Examples include headache, cough, abdominal pain, constipation etc.<ref name="Ergil 2009" /><ref>{{cite journal | vauthors = Vickers AJ, Linde K | title = Acupuncture for chronic pain | journal = JAMA | volume = 311 | issue = 9 | pages = 955–6 | date = March 2014 | pmid = 24595780 | pmc = 4036643 | doi = 10.1001/jama.2013.285478 }}</ref>

Since therapy will not be chosen according to the disease entity but according to the pattern, two people with the same disease entity but different patterns will receive different therapy.<ref name="Flaws 1996" /> Vice versa, people with similar patterns might receive similar therapy even if their disease entities are different. This is called ''yì bìng tóng zhì, tóng bìng yì zhì'' ({{zh|p=|c=异病同治，同病异治|s=|t=|l=different diseases, same treatment; same disease, different treatments|labels=no}}).<ref name="Flaws 1996" />

===Patterns===
In TCM, "pattern" ({{zh|c=证|labels=no|p=zhèng}}) refers to a "pattern of disharmony" or "functional disturbance" within the functional entities of which the TCM model of the body is composed.<ref name="Ergil 2009" /> There are disharmony patterns of qi, xuě, the body fluids, the zàng-fǔ, and the meridians.<ref name="Clavey 1995" /> They are ultimately defined by their symptoms and signs (i.e., for example, pulse and tongue findings).<ref name="Flaws 1996" />

In clinical practice, the identified pattern usually involves a combination of affected entities<ref name="Flaws 1990">Flaws, Bob (1990): [https://books.google.com/books?id=hID3SfkAuzUC&q=tcm+ba+gang+diagnosis&pg=PA5 "Sticking to the Point"] {{Webarchive|url=https://web.archive.org/web/20170320195338/https://books.google.com/books?id=hID3SfkAuzUC&pg=PA5&dq=tcm+ba+gang+diagnosis&hl=zh-CN#v=onepage&q=tcm%20ba%20gang%20diagnosis&f=false |date=20 March 2017}} Blue Poppy Press. 10th Printing, 2007. {{ISBN|978-0-936185-17-0}}</ref> (compare with typical examples of patterns).

====Six Excesses====
The Six Excesses ({{zh|labels=no|c=六淫|p=liù yín}},<ref name="Wiseman 1996" /> sometimes also translated as "Pathogenic Factors",<ref name="1U3dN">{{cite book|url=https://books.google.com/books?id=WbThUt45ZXgC&q=tcm+six&pg=PA159|title=Foundations for integrative musculoskeletal medicine: an east-west approach|author=Marcus & Kuchera|publisher=North Atlantic Books|year=2004|access-date=22 March 2011|isbn=978-1-55643-540-9}} p. 159</ref> or "Six Pernicious Influences";<ref name="Ross 1984" /> with the alternative term of {{zh|c=六邪|labels=no|p=liù xié}}, – "Six Evils" or "Six Devils")<ref name="Ross 1984" /> are allegorical terms used to describe disharmony patterns displaying certain typical symptoms.<ref name="Ergil 2009" /> These symptoms resemble the effects of six climatic factors.<ref name="Ross 1984" /> In the allegory, these symptoms can occur because one or more of those climatic factors (called {{zh|c=六气|labels=no|p=liù qì}}, "the six qi")<ref name="Deng 1999" /> were able to invade the body surface and to proceed to the interior.<ref name="Ergil 2009" /> This is sometimes used to draw causal relationships (i.e., prior exposure to wind/cold/etc. is identified as the cause of a disease),<ref name="Deng 1999" /> while other authors explicitly deny a direct cause-effect relationship between weather conditions and disease,<ref name="Ergil 2009" /><ref name="Ross 1984" /> pointing out that the Six Excesses are primarily descriptions of a certain combination of symptoms<ref name="Ergil 2009" /> translated into a pattern of disharmony.<ref name="Ross 1984" /> It is undisputed, though, that the Six Excesses can manifest inside the body without an external cause.<ref name="Ergil 2009" /><ref name="Wiseman 1996" /> In this case, they might be denoted "internal", e.g., "internal wind"<ref name="Wiseman 1996" /> or "internal fire (or heat)".<ref name="Wiseman 1996" />

The Six Excesses and their characteristic clinical signs are:
# Wind ({{zh|c=风|labels=no|p=fēng}}): rapid onset of symptoms, wandering location of symptoms, itching, nasal congestion, "floating" pulse;<ref name="Deng 1999" /> tremor, paralysis, convulsion.<ref name="Ergil 2009" />
# Cold ({{zh|c=寒|labels=no|p=hán}}): cold sensations, aversion to cold, relief of symptoms by warmth, watery/clear excreta, severe pain, abdominal pain, contracture/hypertonicity of muscles, (slimy) white tongue fur, "deep"/"hidden" or "string-like" pulse,<ref name="jvz68">{{harvp|Wiseman|Ellis|1996|pp=80, 142}}</ref> or slow pulse.<ref name="Ross 1984" />
# Fire/Heat ({{zh|c=火|labels=no|p=huǒ}}): aversion to heat, high fever, thirst, concentrated urine, red face, red tongue, yellow tongue fur, rapid pulse.<ref name="Ergil 2009" /> (Fire and heat are basically seen to be the same)<ref name="Wiseman 1996" />
# Dampness ({{zh|c=湿|labels=no|p=shī}}): sensation of heaviness, sensation of fullness, symptoms of Spleen dysfunction, greasy tongue fur, "slippery" pulse.<ref name="Ross 1984" />
# Dryness ({{zh|c=燥|labels=no|p=zào}}): dry cough, dry mouth, dry throat, dry lips, nosebleeds, dry skin, dry stools.<ref name="Ergil 2009" />
# Summerheat ({{zh|c=暑|labels=no|p=shǔ}}): either heat or mixed damp-heat symptoms.<ref name="Wiseman 1996" />
Six-Excesses-patterns can consist of only one or a combination of Excesses (e.g., wind-cold, wind-damp-heat).<ref name="Deng 1999" /> They can also transform from one into another.<ref name="Deng 1999" />

====Typical examples of patterns====
For each of the functional entities (qi, xuĕ, zàng-fǔ, meridians etc.), typical disharmony patterns are recognized; for example: qi vacuity and qi stagnation in the case of qi;<ref name="Wiseman 1996" /> blood vacuity, blood stasis, and blood heat in the case of xuĕ;<ref name="Wiseman 1996" /> Spleen qi vacuity, Spleen yang vacuity, Spleen qi vacuity with down-bearing qi, Spleen qi vacuity with lack of blood containment, cold-damp invasion of the Spleen, damp-heat invasion of Spleen and Stomach in case of the Spleen zàng;<ref name="Ergil 2009" /> wind/cold/damp invasion in the case of the meridians.<ref name="Flaws 1996" />

TCM gives detailed prescriptions of these patterns regarding their typical symptoms, mostly including characteristic tongue and/or pulse findings.<ref name="Wiseman 1996" /><ref name="Flaws 1996" /> For example:
* "Upflaming Liver fire" ({{zh|c=肝火上炎|labels=no|p=gānhuǒ shàng yán}}): Headache, red face, reddened eyes, dry mouth, nosebleeds, constipation, dry or hard stools, profuse menstruation, sudden [[Medicine:Tinnitus|tinnitus]] or deafness, vomiting of sour or bitter fluids, expectoration of blood, irascibility, impatience; red tongue with dry yellow fur; slippery and string-like pulse.<ref name="Wiseman 1996" />

====Eight principles of diagnosis====
The process of determining which actual pattern is on hand is called {{lang|zh|辩证}} ({{zh|labels=no|p=biàn zhèng}}, usually translated as "pattern diagnosis",<ref name="Ergil 2009" /> "pattern identification"<ref name="Wiseman 1996" /> or "pattern discrimination"<ref name="Flaws 1990" />). Generally, the first and most important step in pattern diagnosis is an evaluation of the present signs and symptoms on the basis of the "Eight Principles" ({{zh|c=八纲 |labels=no|p=bā gāng}}).<ref name="Ergil 2009" /><ref name="Wiseman 1996" /> These eight principles refer to four pairs of fundamental qualities of a disease: exterior/interior, heat/cold, vacuity/repletion, and yin/yang.<ref name="Wiseman 1996" /> Out of these, heat/cold and vacuity/repletion have the biggest clinical importance.<ref name="Wiseman 1996" /> The yin/yang quality, on the other side, has the smallest importance and is somewhat seen aside from the other three pairs, since it merely presents a general and vague conclusion regarding what other qualities are found.<ref name="Wiseman 1996" /> In detail, the Eight Principles refer to the following:
* ''Yin and yang'' are universal aspects all things can be classified under, this includes diseases in general as well as the Eight Principles' first three couples.<ref name="Wiseman 1996" /> For example, cold is identified to be a yin aspect, while heat is attributed to yang.<ref name="Wiseman 1996" /> Since descriptions of patterns in terms of yin and yang lack complexity and clinical practicality, though, patterns are usually not labeled this way anymore.<ref name="Wiseman 1996" /> Exceptions are vacuity-cold and repletion-heat patterns, who are sometimes referred to as "yin patterns" and "yang patterns" respectively.<ref name="Wiseman 1996" />
* ''Exterior'' ({{zh|c=表|labels=no|p=biǎo}}) refers to a disease manifesting in the superficial layers of the body – skin, hair, flesh, and meridians.<ref name="Wiseman 1996" /> It is characterized by aversion to cold and/or wind, headache, muscle ache, mild fever, a "floating" pulse, and a normal tongue appearance.<ref name="Wiseman 1996" />
* ''Interior'' ({{zh|c=里|labels=no|p=lǐ}}) refers to disease manifestation in the zàng-fǔ, or (in a wider sense) to any disease that can not be counted as exterior.<ref name="Deng 1999" /> There are no generalized characteristic symptoms of interior patterns, since they'll be determined by the affected zàng or fǔ entity.<ref name="Wiseman 1996" />
* ''Cold'' ({{zh|c=寒|labels=no|p=hán}}) is generally characterized by aversion to cold, absence of thirst, and a white tongue fur.<ref name="Wiseman 1996" /> More detailed characterization depends on whether cold is coupled with vacuity or repletion.<ref name="Wiseman 1996" />
* ''Heat'' ({{zh|c=热|labels=no|p=rè}}) is characterized by an absence of aversion to cold, a red and painful throat, a dry tongue fur and a rapid and floating pulse if it falls together with an exterior pattern.<ref name="Wiseman 1996" /> In all other cases, symptoms depend on whether heat is coupled with vacuity or repletion.<ref name="Wiseman 1996" />
* ''Deficiency'' ({{zh|c=虚|labels=no|p=xū}}), can be further differentiated into deficiency of qi, xuě, yin and yang, with all their respective characteristic symptoms.<ref name="Wiseman 1996" /> Yin deficiency can also cause "empty-heat".<ref name="Kaptchuck 2000" />
* ''Excess'' ({{zh|c=实|labels=no|p=shí}}) generally refers to any disease that can't be identified as a deficient pattern, and usually indicates the presence of one of the Six Excesses,<ref name="Deng 1999" /> or a pattern of stagnation (of qi, xuě, etc.).<ref name="hM4aY">Tierra & Tierra 1998, p. 108</ref> In a concurrent exterior pattern, excess is characterized by the absence of sweating.<ref name="Wiseman 1996" />

After the fundamental nature of a disease in terms of the Eight Principles is determined, the investigation focuses on more specific aspects.<ref name="Wiseman 1996" /> By evaluating the present signs and symptoms against the background of typical disharmony patterns of the various entities, evidence is collected whether or how specific entities are affected.<ref name="Wiseman 1996" /> This evaluation can be done
# in respect of the meridians ({{zh|c=经络辩证|labels=no|p=jīngluò biàn zhèng}})<ref name="Flaws 1990" />
# in respect of qi ({{zh|c=气血辩证, |labels=no|p=qì xuè biàn zhèng}})<ref name="Flaws 1990" />
# in respect of xuè ({{zh|c=气血辩证|labels=no|p=qì xuè biàn zhèng}})<ref name="Flaws 1990" />
# in respect of the body fluids ({{zh|c=津液辩证|labels=no|p= jīnyè biàn zhèng}})<ref name="Flaws 1990" />
# in respect of the zàng-fǔ ({{zh|c=脏腑辩证|labels=no|p= zàngfǔ biàn zhèng}})<ref name="Flaws 1990" /> – very similar to this, though less specific, is disharmony pattern description in terms of the Five Elements [{{zh|c=五行辩证|labels=no|p=wǔ xíng biàn zhèng}}]<ref name="Flaws 1996" />)

There are also three special pattern diagnosis systems used in case of febrile and infectious diseases only ("Six Channel system" or "six division pattern" &#91;{{zh|c=六经辩证|labels=no|p=liù jīng biàn zhèng}}&#93;; "Wei Qi Ying Xue system" or "four division pattern" [{{zh|c=卫气营血辩证|labels=no|p=weì qì yíng xuè biàn zhèng}}]; "San Jiao system" or "three burners pattern" &#91;{{zh|c=三焦辩证|labels=no|p=sānjiaō biàn zhèng}}&#93;).<ref name="Flaws 1996" /><ref name="Clavey 1995" />

====Considerations of disease causes====
Although TCM and its concept of disease do not strongly differentiate between cause and effect,<ref name="Ross 1984">Ross, Jeremy (1984) [https://books.google.com/books?id=t23zKB1FSVYC&q=Chinese+medicine+is+completely+different%3B+it+emphasizes+function.+Little&pg=PA6 "Zang Fu, the organ systems of traditional Chinese medicine"] Elsevier. First edition 1984. {{ISBN|978-0-443-03482-4}}</ref> pattern discrimination can include considerations regarding the disease cause; this is called {{lang|zh|病因辩证}} ({{zh|labels=no|p=bìngyīn biàn zhèng}}, "disease-cause pattern discrimination").<ref name="Flaws 1990" />

There are three fundamental categories of disease causes ({{zh|c=三因|labels=no|p=sān yīn}}) recognized:<ref name="Wiseman 1996" />
# external causes: these include the Six Excesses and "Pestilential Qi".<ref name="Wiseman 1996" />
# internal causes: the "Seven Affects" ({{zh|c=七情|labels=no|p=qī qíng}},<ref name="Wiseman 1996" /> sometimes also translated as "Seven Emotions"<ref name="Ross 1984" />) – joy, anger, brooding, sorrow, fear, fright and grief.<ref name="Ross 1984" /> These are believed to be able to cause damage to the functions of the zàng-fú, especially of the Liver.<ref name="Wiseman 1996" />
# non-external-non-internal causes: dietary irregularities (especially: too much raw, cold, spicy, fatty or sweet food; voracious eating; too much alcohol),<ref name="Wiseman 1996" /> fatigue, sexual intemperance, trauma, and parasites ({{zh|c=虫|labels=no|p=chóng}}).<ref name="Wiseman 1996" />

==Diagnostics==
In TCM, there are five major diagnostic methods: inspection, auscultation, olfaction, inquiry, and palpation.<ref name="Cheng 1987">{{cite book | vauthors = Cheng X | title = Chinese Acupuncture and Moxibustion (1st ed.) | year = 1987 | publisher = Foreign Languages Press | isbn = 978-7-119-00378-8}}</ref> These are grouped into what is known as the "Four pillars" of diagnosis, which are Inspection, Auscultation/ Olfaction, Inquiry, and Palpation ({{lang|zh|望，聞，問，切}}).
* Inspection focuses on the face and particularly on the tongue, including analysis of the tongue size, shape, tension, color and coating, and the absence or presence of teeth marks around the edge.
* Auscultation refers to listening for particular sounds (such as wheezing).
* Olfaction refers to attending to body odor.
* Inquiry focuses on the "seven inquiries", which involve asking the person about the regularity, severity, or other characteristics of: chills, fever, perspiration, appetite, thirst, taste, defecation, urination, pain, sleep, menses, leukorrhea.
* Palpation which includes feeling the body for tender [[Unsolved:Acupuncture#Qi, meridians and acupuncture points|A-shi points]], and the palpation of the wrist pulses as well as various other pulses, and palpation of the abdomen.

===Tongue and pulse===
Examination of the tongue and the pulse are among the principal diagnostic methods in TCM. Details of the tongue, including shape, size, color, texture, cracks, teeth marks, as well as tongue coating are all considered as part of tongue diagnosis. Various regions of the tongue's surface are believed to correspond to the zàng-fŭ organs.

Pulse palpation involves measuring the pulse both at a superficial and at a deep level at three different locations on the radial artery (''Cun, Guan, Chi'', located two fingerbreadths from the wrist crease, one fingerbreadth from the wrist crease, and right at the wrist crease, respectively, usually palpated with the index, middle and ring finger) of each arm, for a total of twelve pulses, all of which are thought to correspond with certain zàng-fŭ. The pulse is examined for several characteristics including rhythm, strength and volume, and described with qualities like "floating, slippery, bolstering-like, feeble, thready and quick"; each of these qualities indicates certain disease patterns. Learning TCM pulse diagnosis can take several years.<ref name="qMZOY">{{cite book | vauthors = Wright T, Eisenberg D |title=Encounters with Qi: exploring Chinese medicine |publisher=Norton |location=New York |year=1995 |pages= [https://books.google.com/books?id=DgFA&pg=PA53 53–54]|isbn=978-0-393-31213-3 }}</ref>

===Traditional categorization===
The traditional categorizations and classifications that can still be found today are:
* The classification according to the [[Unsolved:Chinese herbology#Four Natures|Four Natures]] ({{zh|labels=no|c=四气|p=sì qì}}): hot, warm, cool, or cold (or, neutral in terms of temperature)<ref name="Ergil 2009" /> and hot and warm herbs are used to treat cold diseases, while cool and cold herbs are used to treat heat diseases.<ref name="Ergil 2009" />

A recent historian of Chinese medicine remarked that it is "nicely ironic that the specialty of acupuncture -- arguably the most questionable part of their medical heritage for most Chinese at the start of the twentieth century -- has become the most marketable aspect of Chinese medicine." She found that acupuncture as we know it today has hardly been in existence for sixty years. Moreover, the fine, [[Biology:Glossary of botanical terms#filiform|filiform]] needle we think of as the acupuncture needle today was not widely used a century ago. Present day acupuncture was developed in the 1930s and put into wide practice only as late as the 1960s.{{sfnb|Andrews|2013a|pp=237–238}}

===Efficacy===
A 2013 editorial in the American journal ''Anesthesia and Analgesia'' stated that acupuncture studies produced inconsistent results, (i.e. acupuncture relieved pain in some conditions but had no effect in other very similar conditions) which suggests the presence of [[Type I and type II errors#Type I error|false positive results]].  These may be caused by factors like biased study design, poor blinding, and the classification of electrified needles (a type of [[Biology:Transcutaneous electrical nerve stimulation|TENS]]) as a form of acupuncture. The inability to find consistent results despite more than 3,000 studies, the editorial continued, suggests that the treatment seems to be a placebo effect and the existing equivocal positive results are the type of  noise one expects to see after a large number of studies are performed on an inert therapy. The editorial concluded that the best controlled studies showed a clear pattern, in which the outcome does not rely upon needle location or even needle insertion, and since "these variables are those that define acupuncture, the only sensible conclusion is that acupuncture does not work."<ref name="Colquhoun2013">{{cite journal | vauthors = Colquhoun D, Novella SP | title = Acupuncture is theatrical placebo | journal = Anesthesia and Analgesia | volume = 116 | issue = 6 | pages = 1360–3 | date = June 2013 | pmid = 23709076 | doi = 10.1213/ANE.0b013e31828f2d5e | url = http://www.dcscience.net/Colquhoun-Novella-A&A-2013.pdf | access-date = 3 June 2020 | url-status = live |  s2cid = 207135491 | archive-url = https://web.archive.org/web/20181120055409/http://www.dcscience.net/Colquhoun-Novella-A%26A-2013.pdf | archive-date = 20 November 2018 | }}</ref>

[[File:Kyutoshin.JPG|thumb|Acupuncture and moxibustion after cupping in Japan]]
Cupping ({{zh|labels=no|c=拔罐|p=báguàn}}) is a type of Chinese massage, consisting of placing several glass "cups" (open spheres) on the body. A match is lit and placed inside the cup and then removed before placing the cup against the skin. As the air in the cup is heated, it expands, and after placing in the skin, cools, creating lower pressure inside the cup that allows the cup to stick to the skin via [[Physics:Suction|suction]].<ref name="PadyQ">{{cite web | url=http://time.com/4443105/cupping-rio-olympics-michael-phelps/ | title=What is Cupping?

=== Die-da ===
'''Diē-dǎ''' ({{lang|zh|跌打}}) or '''Dit Da''', is a traditional Chinese bone-setting technique, usually practiced by martial artists who know aspects of Chinese medicine that apply to the treatment of trauma and injuries such as bone fractures, sprains, and bruises. Some of these specialists may also use or recommend other disciplines of Chinese medical therapies if serious injury is involved. Such practice of bone-setting ({{zh|labels=no|t=整骨|s=正骨}}) is not common in the West.

China's National People's Congress Standing Committee passed the country's first law on TCM in 2016, which came into effect on 1 July 2017.

During British rule, Chinese medicine practitioners in Hong Kong were not recognized as "medical doctors", which means they could not issue prescription drugs, give injections, etc. However, TCM practitioners could register and operate TCM as "herbalists".<ref>{{cite news|title=香港执业中医的概况|url=http://www.cntv.cn/program/zhyy/topic/health/C12827/20040824/101533.shtml|publisher=央视国际|date=2004-08-24}}</ref> The Chinese Medicine Council of Hong Kong was established in 1999.

===Macau===
The Portuguese Macau government seldom interfered in the affairs of Chinese society, including with regard to regulations on the practice of TCM. There were a few TCM pharmacies in Macau during the colonial period. In 1994, the Portuguese Macau government published Decree-Law no. 53/94/M that officially started to regulate the TCM market. After the sovereign handover, the Macau S.A.R. government also published regulations on the practice of TCM.{{Clarify|date=January 2022}} In 2000, Macau University of Science and Technology and Nanjing University of Traditional Chinese Medicine established the Macau College of Traditional Chinese Medicine to offer a degree course in Chinese medicine.<ref>{{Cite news|title=澳门的高等中医药教育|url=https://eic.tjutcm.edu.cn/info/1005/1140.htm|publisher=世界中医药教育|date=2013-04-19|access-date=1 June 2021|archive-date=6 June 2021|archive-url=https://web.archive.org/web/20210606022709/https://eic.tjutcm.edu.cn/info/1005/1140.htm|url-status=dead}}</ref>

In Macau, the legitimacy of Chinese medicine is not built upon "miracle making".  Instead, it is achieved through a celebration of cultural tradition rejuvenated with discourses of nationalism and modernity, and through the mutual constructions of medical references between doctors and patients.<ref name="somatosphere">{{cite news |last1=Lou|first1=Loretta|url=http://somatosphere.net/2016/beyond-miracles-how-traditional-chinese-medicine-establishes-professional-legitimacy-in-post-colonial-macau.html/ |title=Beyond Miracles: How Traditional Chinese Medicine Establishes Professional Legitimacy in Post-colonial Macau |work=somatosphere |date=2016-12-09 |access-date=2016-12-09}}</ref>
