Ayurveda
There is no good evidence that works or helps for any disease. Some Ayurvedic products have lead, mercury, and arsenic in them. In 2008, nearly 21% of Ayurvedic products sold on the internet and made in India and the United States had in them lead, mercury, and arsenic (heavy metals) in quantities that are toxic. There may be public health dangers that result from this, but that is not known.
