The U.S. Food and Drug Administration warns that the presence of metals in some Ayurvedic products makes them potentially harmful. A 2015 published survey of people who use Ayurvedic preparations showed that 40 percent had elevated blood levels of lead and some had elevated blood levels of mercury.

Why Ayurveda has no side effects?

Ayurvedic medicines may be beneficial to health, but are not devoid of adverse effects. Adverse events may be due to adulteration or some inherent constituents like alkaloids. Adverse effects and adverse events are not the same thing.

Why is Ayurveda wrong?

There is no good evidence that Ayurveda is effective for treating any disease. Ayurvedic preparations have been found to contain lead, mercury, and arsenic, substances known to be harmful to humans.
