Ma huang is a Chinese herb more commonly known as ephedra. Use of products containing ma huang or other ephedrine alkaloids can stimulate the nervous system, which makes it an effective weight-loss aid when combined with caffeine, according to the National Institutes of Health. However, use of ma huang can be dangerous or even deadly. Supplements and other products containing ephedra, including ma huang products, were banned by the Food and Drug Administration in 2004 because of the risk of adverse side effects, including sudden death. Always speak with a doctor before using products containing ma huang.
