London: August 28, 2008 – IR Summary/BBC - Herbal medicine manufactured and used in India for thousands of years are considered effective for most of the diseases and these are increasingly getting popular in the Western countries including the United States but there are certain objections by American Medical Association that some of them contain objectionable content.

A study at Boston University analyzed 193 products of which 20@\% contained high level of lead, mercury and other arsenic supplements, not permissible for human consumption.

Some of the tested products, they said, would result in eating toxic materials as much as 10,000 times more than acceptable levels.

According to the study, there are two types of ayurvedic medicines.

But Dr Saper said there had been more than 80 reported cases of lead poisoning in the world through such remedies in the past 30 years.
