Ephedra (Paperback)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Ephedra, from the plant Ephedra sinica, has been used as a herbal remedy in traditional Chinese medicine for 5,000 years for the treatment of asthma and hay fever, as well as for the common cold. Known in Chinese as ma huang, ephedra is a stimulant which constricts blood vessels and increases blood pressure and heart rate. Several additional species belonging to the genus Ephedra have traditionally been used for a variety of medicinal purposes, and are a possible candidate for the Soma plant of Indo-Iranian religion. Native Americans and Mormon pioneers drank a tea brewed from an Ephedra, called Mormon Tea, but North American ephedras lack the alkaloids found in species such as E. sinica. Ephedra-containing dietary supplements have been linked to a high rate of serious side effects and a number of deaths, leading to concern from the U.S. Food and Drug Administration (FDA), the National Center for Complementary and Alternative Medicine, and the medical community. However, initial efforts to test and regulate ephedra were defeated by lobbying and political pressure from the dietary-supplement industry.
