Role U.S. FDA in Regulating Dietary Supplements
What is FDA's role in regulating dietary supplements versus the manufacturer's responsibility for marketing them? In October 1994, the Dietary Supplement Health and Education Act (DSHEA) was signed into law by President Clinton. Before this time, dietary supplements were subject to the same regulatory requirements as were other foods. This new law, which amended the Federal Food, Drug, and Cosmetic Act, created a new regulatory framework for the safety and labeling of dietary supplements.

"Herbal medicines are preparations derived from naturally occurring plants with medicinal or preventive properties. The World Health Organization (WHO) estimates that 4 billion people, amounting to 80% of the world's population, use herbal medicines for some aspect of primary health care. Herbal medicine is a major component in all indigenous peoples' traditional medicine and a common element in Ayurvedic, homeopathic, naturopathic, traditional oriental, and Native American medicine. The foods early humans ate contained a million different phytochemicals and through modern science we are also recognizing some of these as functional foods (e.g. green tea catechins and pomegranate ellagitannins).
Many spices such as cayenne and curcumin have medicinal properties in addition to their roles in flavoring foods. Today, we are rediscovering the utility of herbal medicines as botanical dietary supplements with potentially important preventive and medicinal effects. However, when patients talk about using herbal medicines, primary care physicians often lack the knowledge to provide informed advice on their use or misuse."

Manufacturers are required to substantiate the identity, purity, quality, strength, and composition of dietary supplements
In the United States, herbal products are marketed under the provisions of the Dietary Supplement. Health and Education Act of 1994, which prohibits their sale for the diagnosis, treatment, cure, or prevention of disease. In 2007, the U.S. Food and Drug Administration (FDA) took further action toward protecting consumers' health when it issued a final rule establishing current good manufacturing practice requirements (CGMP) for dietary supplements. Under the final rule, manufacturers are required to substantiate the identity, purity, quality, strength, and composition of dietary supplements, and, further, to report all serious dietary supplement adverse events to the FDA.
