In this program, ABC News correspondent Arnold Diaz reports on the potential dangers of dietary supplements. Pharmacologist and radio host Joe Graedon; Tod Cooperman, president of ConsumerLab.com; and David Seckman, executive director of the National Nutritional Foods Association, speak out about misleading labeling, the need for governmental regulation, and the popular misperception among consumers that supplements such as chondroitin, SAM-e, ginseng, ginkgo biloba, and St. John’s wort are harmless. The bottom line? Herbals have medicinal qualities, so safe use requires that dosage levels and possible interactions with pharmaceuticals be strictly taken into account. (14 minutes)
