More Studies Needed Before Labeling Herbs

The Jan. 17 article (“Which Herb Helps What? Labels Can Now Say”) constitutes a step backward by the U.S. Food and Drug Administration. Although there are probably some benefits to be derived from herbs and dietary supplements, for the most part, positive results are likely due to the placebo effect. The labeling is largely based on anecdotal reports. There may sometimes even be harm, especially when herbs and supplements are mixed with certain prescription drugs.

Until scientific studies supporting the claims made by the distributors of herbs and supplements are done, labels describing what these products can be used for should not be allowed.
