What Are Ephedra Alkaloids?
Ephedra’s basic ingredients are the alkaloids ephedrine and pseudoephedrine. The stem comprises 1-3% total alkaloids, with ephedrine making up 30-90% of this total, dependent on the type of ephedra plant specie. Ephedrine stimulates the central nervous system, increases heart rate, increases blood pressure, and dilates the bronchial tubes. Pseudoephedrine (synthetic form) is a common nonprescription remedy for the alleviation of nasal congestion.
