Ephedra is a genus of gymnosperm shrubs, the only genus in the family Ephedraceae and order Ephedrales. These plants occur in dry climates over a wide area mainly in the northern hemisphere, across southern Europe, north Africa, southwest and central Asia, southwestern North America, and, in the southern hemisphere, in South America south to Patagonia. They are also called Joint-pine, Jointfir, or Mormon-tea. The Chinese name is 麻黄, má huáng, which means "yellow hemp". Ephedra is also sometimes called sea grape (from the French raisin de mer), although that is also a common name for Coccoloba uvifera.
Medical uses
- Main article: Ephedra
Plants of the Ephedra genus, including E. sinica and others, have traditionally been used by indigenous people for a variety of medicinal purposes, including treatment of asthma, hay fever, and the common cold.[1] They have also been proposed as a candidate for the Soma plant of Indo-Iranian religion. The alkaloids ephedrine and pseudoephedrine are active constituents of E. sinica and other members of the genus. These compounds are sympathomimetics with stimulant and decongestant qualities and are related chemically to the amphetamines. Ephedra nevandensis contains ephedrine in its roots, stems and branches.[2] Ephedra distachya contains up to 3% ephedrine in the entire plant.[3] Ephedra sinica contains approximately 2.2% ephedrine.[4]
