St. John's wort is one of 200 plant products approved by the U.S. Food and Drug Administration (FDA) for sale to the public as a dietary supplement. The FDA does not subject dietary supplements to an extensive pre-market approval process, however, as it does new drugs.
On the other hand, the Dietary Supplement Health and Education Act of 1994 permits the FDA to remove a supplement from the market if it determines the supplement is unsafe. Herbal products such as St. John's wort can be marketed without stating standards for dosage or evidence of safety. Often, information on specific products may be misleading or even inaccurate.
