Ephedra-Containing Dietary Supplements in the US versus Ephedra as a Chinese Medicine

Abstract

Ephedra has been commonly used in traditional Chinese medicine (TCM) without significant adverse effects. Ephedra-containing dietary supplements are widely used in the United States to promote weight reduction and energy enhancement. However, there are significant safety concerns regarding the use of ephedra-containing dietary supplements, especially when such use occurs by consumers without medical supervision. This article reviews and contrasts the usage of ephedra as a dietary supplement in the US against an herbal medication in TCM. The potential adverse effects of ephedra-containing dietary supplements are also reviewed.
