The U.S. Food and Drug Administration (FDA) advises consumers to stop using dietary supplements containing ephedra. In order to protect consumers, the FDA published a final rule on April 12, 2004, that bans the sale of dietary supplements containing ephedrine alkaloids.
After a careful review of the available evidence about the risks and benefits of ephedra in supplements, the FDA found that these supplements present an unreasonable risk of illness or injury to consumers. The data showed little evidence of ephedra's effectiveness, except for short-term weight loss, while confirming that the substance raises blood pressure and stresses the heart. The increased risk of heart problems and strokes negates any benefits of weight loss.
