Ma huang is a specific form of a type of plant known as ephedra. Also known by its scientific name, Ephedra sinica, ma huang was used for hundreds of years in China and India as an herbal treatment for conditions such as colds, the flu, fever, asthma and nasal congestion.
In recent years, dietary supplements containing ma huang have been marketed to consumers under names like herbal Fen Phen as a way to lose weight. These products contain varying amounts of the ephedra alkaloids ephedrine and pseudoephedrine; when combined with St. John’s wort, supplements containing these chemicals are supposed to help a person with weight loss.
In April 2004, the Food and Drug Administration banned dietary supplements containing ephedra, including those made from ma huang. The agency said that these products had been associated with a number of serious and potentially deadly side effects, including heart attack, stroke, high blood pressure, tachycardia and other heart problems. The FDA said that it received thousands of reports of side effects from ephedra and ma huang products, including more than 150 deaths.
