Short description: Common name for several daisy-like plants
German chamomile, Matricaria chamomilla
Roman chamomile, Chamaemelum nobile

Chamomile (American English) or camomile (British English; see spelling differences) (/ˈkæməmaɪl, -miːl/ KAM-ə-myle or KAM-ə-meel[1][2]) is the common name for several daisy-like plants of the family Asteraceae. Two of the species, Matricaria chamomilla and Chamaemelum nobile, are commonly used to make herbal infusions for beverages.[3][4][5] There has been limited (though thus far insufficient) research as to whether consuming chamomile in foods or beverages is effective in treating medical conditions, although in Hungarian it is referred to as the "king of herbs" (orvosi székfű).[4][5]

Etymology

The word chamomile is derived via French and Latin, from the Greek Ancient Greek:, from Ancient Greek:, and Ancient Greek:.[6][7] First used in the 13th century, the spelling chamomile corresponds to the Latin chamomilla and the Greek chamaimelon.[7] The spelling camomile is a British derivation from the French.[7]

Species

Loose-leaf chamomile tea

Some commonly used species include:

  • Matricaria chamomilla – often called "German chamomile" or "Water of Youth"[8]
  • Chamaemelum nobile – Roman, English, or garden chamomile; also frequently used (C. nobile Treneague is normally used to create a chamomile lawn)[9]

A number of other species' common names include the word chamomile. This does not mean they are used in the same manner as the species used in the herbal tea known as "chamomile". Plants including the common name chamomile, of the family Asteraceae, are:

Uses

Tea

Chamomile tea is a herbal infusion made from dried flowers and hot water, and may improve sleep quality.[3] Two types of chamomile are used, namely German chamomile (Matricaria recutita) and Roman chamomile (Chamaemelum nobile).[3]

Use in beer and ale

Chamomile has historically been used in making beer and ale.[12] Unlike for tea, in which only the flowers are used, the whole plant has been used to make beers and ales, adding a bitter flavor component favored by craft breweries and homebrewers.[13][14]

Research

The main compounds of interest in chamomile flowers are coumarins, flavonoids, and polyphenols,[8] including apigenin, quercetin, patuletin, luteolin, and daphnin.[15][16] It is currently unclear whether chamomile is effective in treating any medical conditions.[5] Chamomile is under preliminary research for its potential anti-anxiety properties.[8] There is no high-quality clinical evidence that it is useful for treating insomnia.[17]

Drug interactions

The use of chamomile has the potential to cause adverse interactions with numerous herbal products and prescription drugs and may worsen pollen allergies.[5] People who are allergic to ragweed (also in the daisy family) may be allergic to chamomile due to cross-reactivity.[3]

Chamomile is not recommended to be taken with aspirin or non-salicylate NSAIDs (non-steroidal anti-inflammatory drugs), as it may cause drug–herb interaction. Chamomile consists of several ingredients including coumarin, glycoside, herniarin, flavonoid, farnesol, nerolidol and germacranolide. Despite the presence of coumarin, as chamomile's effect on the coagulation system has not yet been studied, it is unknown whether a clinically significant drug–herb interaction exists with anticoagulant drugs.[5] However, until more information is available, it is not recommended to use these substances concurrently.[18]

Chamomile should not be used by people with past or present cancers of the breast, ovary, or uterus; endometriosis; or uterine fibroids.[5]

Pregnancy and breastfeeding

Because chamomile has been known to cause uterine contractions that can invoke miscarriage, pregnant women are advised to not consume Roman chamomile (Chamaemelum nobile).[4] Although oral consumption of chamomile is generally recognized as safe in the United States, there is insufficient clinical evidence about its potential for affecting nursing infants.[5]

Agriculture

The chamomile plant is known to be susceptible to many fungi, insects, and viruses. Fungi such as Albugo tragopogonis (white rust), Cylindrosporium matricariae, Erysiphe cichoracearum (powdery mildew), and Sphaerotheca macularis (powdery mildew) are known pathogens of the chamomile plant. Aphids have been observed feeding on chamomile plants and the moth Autographa chryson causes defoliation.[citation needed]

Historical descriptions

The 11th century part of Old English Illustrated Herbal has an illustrated entry.[19] Nicholas Culpeper's 17th century The Complete Herbal has an illustration and several entries on chamomel.[20][21]

In culture

  • In The Tale of Peter Rabbit by Beatrix Potter (1902), Peter is given chamomile tea after being chased by Mr. McGregor.[22]
  • Mary Wesley's 1984 novel The Camomile Lawn features a house in Cornwall with a lawn planted with chamomile rather than grass.
  • In the 2001 No Doubt song "Hey Baby", chamomile is featured in the line "I'm just sippin' on chamomile", sung by Gwen Stefani.
  • Chamomile is the national flower of Russia.[23]
