SOME PROBLEMS PERSIST WITH GINSENG SUPPLEMENTS BUT OVERALL QUALITY IMPROVES ACCORDING TO CONSUMERLAB.COM
— Test Results Published Online Today —
WHITE PLAINS, NY — August 28, 2003 — In contrast to its testing three years ago in which nearly 60% of Asian and American Ginseng supplements were found to have significant problems, testing of recently purchased products by ConsumerLab.com found problems with a far lower percentage — 17%. In one of five products claiming to contain "Korean Ginseng" a high amount of the pesticide hexachlorobenzene was found. In 2000, most Korean Ginseng products showed pesticide contamination. Hexachlorobenzene is a probable human carcinogen and is banned from most crop use throughout the world. One other product that failed the new testing was a liquid "Chinese Ginseng" sold in single-dose bottles. Despite being labeled "EXTRA STRENGTH" this product contained less than 10% of the expected ginsenosides — biologically active constituents of ginseng. In 2000, more than 30% of ginseng products tested low in ginsenosides.
Ginseng is used for many purposes, although most commonly to improve overall energy during times of stress. While there is not much clinical evidence to support an energy boosting effect, there are studies showing its potential value in normalizing blood glucose levels in diabetics, helping to stimulate immunity and treat male impotence, and, when used with ginkgo biloba, improving memory and symptoms of attention deficit-hyperactivity disorder (ADHD) in children.
Remarking on the findings, Dr. Tod Cooperman, ConsumerLab.com's President, said, "The problems that we identified with ginseng in 2000 were an eye-opener for consumers and the industry. We would like to think that this has contributed to the apparent improvement in quality — although consumers clearly must remain cautious."
