Ayurvedic Medecine Safety Issues

Major safety concerns include adulteration of herbal medicines with toxic metals, and intrinsic toxicity of herbal medications. Some traditional Ayurvedic treatments use toxic metals, herbs, and minerals as part of their remedies. Rasa Shastra, the practice of adding metals, minerals or gems to herbs, increases the likelihood of toxic metals such as lead, mercury, or arsenic in the remedy.

A 2004 study found toxic heavy metals such as lead, mercury and arsenic in 20% of Ayurvedic preparations that were made in South Asia for sale around Boston and extrapolated the data to America. It concluded that excess consumption of these products could cause health risks. A 2008 study found that approximately 20% of remedies (and 40% of rasa shastra medicines) purchased over the internet from both US and Indian suppliers were contaminated with toxic metals.

Traditionally the toxicity of these materials are believed to be reduced through processes such as samskaras or shodhanas (for metals), which is similar to the Chinese pao zhi, although the Ayurvedic technique is more complex and may involve prayers as well as physical pharmacy techniques. Rigorous evidence that the metals may be rendered nontoxic is not available, and case reports describe adverse effects to these metals.

There is evidence that using some Ayurvedic medicines, especially those involving herbs, metals, minerals, or other materials involves potentially serious risks, including toxicity. Adverse reactions to herbs due their pharmacology are described in traditional Ayurveda texts, but Ayurvedic practitioners are reluctant to admit that herbs could be toxic and the reliable information on herbal toxicity is not easily available.
