Safety Issues

Ayurvedic therapy presents numerous potential safety concerns. One serious problem is that many Ayurvedic herbs have never undergone a formal safety evaluation, and those that have been evaluated have not necessarily been proven harmless. For more information on safety risks with individual Ayurvedic herbs, see the following articles: andrographis , ashwagandha , boswellia , Coleus forskohlii, dandelion , fenugreek , garlic , ginger , gotu kola , guggul , gymnema , neem , phyllanthus , turmeric , and tylophora .

Most of the proprietary herbal formulas described in this article have undergone a certain amount of safety testing by the manufacturer and were found reassuringly nontoxic; however, verification of safety by independent laboratories that maintain modern standards remains limited. Some traditional Ayurvedic formulas may contain toxic levels of heavy metals, especially lead, mercury, and arsenic. 1 According to one study, approximately one in five US and Indian produced Ayurvedic medicine contained detectable amounts of at least one of these heavy metals. 2 In one particularly dramatic and tragic case report, a brain-damaged child born to a mother using an Ayurvedic formula was found to have the highest bloods levels of lead ever recorded in a living newborn. 3 Analysis of the formula revealed a very high lead content, along with toxic levels of mercury.

There are other concerns as well. For example, oral silver, a traditional Ayurvedic remedy, can cause permanent gray-black staining of the skin and mucous membranes. 4 The dietary recommendations made within the context of Ayurvedic theory could conceivably lead to inadequate intake of essential nutrients, and hence malnutrition. However, most reputable Ayurvedic practitioners are well aware of modern nutrition knowledge and take care to make reasonable recommendations within that context.

Various traditional Ayurvedic techniques, such as bloodletting and drinking urine, clearly suggest possible health risks. Fortunately, most modern Ayurvedic practitioners shun the most worrisome of these methods.

In a case report, a patient taking the antidepressant sertraline had two relapses of depression soon after taking an Ayurvedic herbal mixture containing Terminalia chebula and Commiphora wighteii. The authors interpreted this as a likely adverse drug-herb interaction. 5 Finally, one study found that an Ayurvedic herbal formula called Trikatu (a mixture of black pepper and ginger) can reduce the effectiveness of the standard anti-inflammatory drug diclofenac. 6 This finding was somewhat surprising as black pepper is generally thought to enhance the absorption of and activity of various medications through a number of known chemical interactions.

FDA Warning:

The presence of heavy metals in some Ayurvedic products makes them potentially harmful. Studies have found detectable levels of lead, mercury, and arsenic. Labeled as "Indian" or "South Asian," these products are sold online and in stores. The Food and Drug Administration (FDA) does not review or approve Ayurvedic products, which can be especially harmful to children. For more information, read the FDA's warning

It is laughable that the FDA which approves potentially harmful chemical laden drugs is criticizing a 5000 year old time tested system.Certain Ayurvedic formulations does have metals in them but those are added by making it undergo several purificatory processes and made fit for consumption. It should only be prescribed by a qualified Ayurveda doctor and its supply online and over the counter should be banned. As potentially harmful chemicals are processed and prescribed for diseases in modern medicine, the same way metals and minerals are done in Ayurveda. The pharma lobby will desperately try to block the popularity of Ayurveda in the US and Europe but it has been there for so long in India and Asia and before any kind of pharmacological development in the primordial world,the US and European nation would be the losers.

I agree--Ayurveda is a powerful science. Although it took 2 decades, I am encouraged by the growth and reimbursement around acupuncture and chiropractry which is now commonplace. I hope that we can continue to see the same sort of traction for Ayurveda. Is there an organization that can take on this cause?

I overviewed the efficacy and the safety literature of the aforementioned Liv.52, but neither heavy metals, nor other toxic elements were not found if the prescriber uses the recommended dose. There are no any medicine in allopathy or ayuerveda which the patient may use without any control sn supervision. The doctors of East and West shoul not block the activity of the oethr site, but must find mutualities and interfaces. In case of ayurveda there are the followings based on an experiences of thousand year: early diagnosis, prophylaxis, role of diet and excercises, "rejuvenation " (an other wording would be better) and harmonisation of the equilibrium states in the body. These should be a good initial step for cooperation.
