Camel urine is a liquid by-product of metabolism in a camel's anatomy. Urine from Arabian camels has been used in the Arabian Peninsula for medicinal purposes for centuries, being a part of ancient Bedouin practices.[1] After the spread of MERS-CoV infections, the World Health Organization urged people to refrain from drinking "raw camel milk or camel urine or eating meat that has not been properly cooked".

Anatomy

Camel urine comes out as a thick syrup.[2][3][4][5]

The kidneys and intestines of a camel are very efficient at reabsorbing water. Camels' kidneys have a 1:4 cortex to medulla ratio.[6] Thus, the medullary part of a camel's kidney occupies twice as much area as a cow's kidney. Secondly, renal corpuscles have a smaller diameter, which reduces surface area for filtration. These two major anatomical characteristics enable camels to conserve water and limit the volume of urine in extreme desert conditions.[7]

Each kidney of an Arabian camel has a capacity around 0.86 litres, and can produce urine with high chloride concentrations. Like the horse, the dromedary has no gall bladder, an organ that requires water to function.[8] Consequently bile flows constantly.[9] Most food is digested and absorbed into the bloodstream from the small intestine. Any remaining liquids and roughage move into the large intestine.

Hadith on Camel Urine

A hadith in Book 4 (Ablution) of al-Bukhari's collection narrated by Anas ibn Malik was used to promote the consumption of Arabian camel urine as a medicine.[10][11] The Islamic prophet Muhammad is said to have advised some diseased people to use it "till their bodies became healthy. [12][1] [13] The authentic hadith[14] also states "Some people of ‘Ukl or ‘Uraina tribe came to Medina and its climate did not suit them ... So the Prophet ordered them to go to the herd of Milch camels and to drink their milk and urine (as a medicine). ... So they went as directed and after they became healthy".[12] Bukhari also narrated, an otherwise identical version of this Hadith, without the mention of "urine".[15] The event has also been recorded in Sahih Muslim, History of the Prophets and Kings and Kitāb aṭ-ṭabaqāt al-kabīr.[16][17][18]

Indian Islamic scholar, Mohammad Najeeb Qasmi, notes various theories proposed by Hanafi and Shaafi’e scholars for a canonical understanding of the implications. This book refers to topical application of milch camel urine as the actual word of the saying has the word Azmadu which means to apply a layer of something.[19] However, Bachtiar Nasir, an Islamic scholar, advocated for and defended the consumption of camel urine, claiming the mixture of camel urine and milk has medicinal benefits. In response, scientists in Muslim and non-Muslim majority countries rejected those claims, and actually link the consumption of camel urine to the spread of a disease known as Middle East respiratory syndrome-related coronavirus (MERS).[20][21]

Medieval times

Avicenna in The Canon of Medicine noted that a diet of camel milk and Arabian camel urine can be beneficial for diseases of the liver.[22] [23]

Usage and effects

In Yemen, it is drunk and is used for treating ailments, though it has been widely denounced.[1] Some salons are said use it as a treatment for hair loss.[1] The camel urine from a virgin camel is priced at twenty dollars per liter, with herders saying that it has curative powers. It is traditionally mixed with milk.[1]

In 2012, a study conducted at the Department of Molecular Oncology of King Faisal Specialist Hospital and Research Center, and published in the Journal of Ethnopharmacology, found that camel urine contains anti-cancerous agents that are cytotoxic against various, but not all, human cancer cell lines in vitro.[24]

In 2017, experimental infections of dromedaries with MERS‐CoV didn't show any evidence of virus in the urine. Therefore, the camel urine is an unlikely source of virus transmission to humans.[25][26]

In 2019 the World Health Organization has said that camels are the source of the Middle East respiratory syndrome-related coronavirus and has urged people who have "diabetes, renal failure, chronic lung disease, and immunocompromised persons are considered to be at high risk of severe disease from MERS-CoV infection" to avoid contact with camels, drinking raw camel milk or camel urine, or eating meat that has not been properly cooked.[27][21][28][29][30]

In 2020, the WHO said, "People should avoid drinking raw camel milk or camel urine or eating meat that has not been properly cooked".[31]
