Vital Signs
Hazards: Toxic Metals Found in Health Products
By ERIC NAGOURNEY
People who buy ayurvedic medicines, commonly used around the world by Indians and other people from South Asia, may be getting more than they bargained for.
Researchers who looked at almost 200 ayurvedic products bought in the United States found that about a fifth contained lead, mercury or arsenic, sometimes at dangerously high levels.
Writing in the Aug. 27 issue of The Journal of the American Medical Association, the researchers said government regulators should establish daily dose limits for toxic metals in dietary supplements and require manufacturers to have their products tested for compliance.
The researchers, led by Dr. Robert B. Saper of the Boston Medical Center, bought the medicines over the Internet in 2005. Some of the products were made in India and others in the United States, but the prevalence of the metals was about the same for both countries, the study said.
In some cases, the presence of the metals may have been no accident. A form of ayurveda, rasa shastra, involves adding some of the materials to the medicine, the researchers said, and those types of products had the highest levels of the metals. But the metals were also found in some of the medicines described as herbal only.
The researchers questioned the belief of rasa shastra practitioners that when the preparations are made correctly, the metals cause no harm.
