Quote:
Ephedra is an erect branching shrub that can be found in arid regions all over the world. The shrubs can be anywhere from 1 and 1/2 to 4 feet tall and generally grow on dry, rocky, or sandy slopes. The branches are slender and have two very small leaf scales at each node. In the fall, the mature, double-seeded cones are visible. The nodes of the ephedra plant are said to be toxic.
Chemical Composition:
Most significant is the alkaloid content, which can reach 3.3%. 40-90 percent of this content is ephedrine and the remaining alkaloids are primarily pseudoephedrine and norpseudoephedrine.
