A member asked:
How much of ephedra is contained in the herb ma huang?
A doctor has provided 1 answer
It is the same: Ephedra sinica , a species of ephedra (ma huang), contains the alkaloids Ephedrine (ephedrine sulfate) and pseudoephedrine, which have been found to induce central nervous system stimulation, bronchodilation, and vasoconstriction. In combination with caffeine, Ephedrine (ephedrine sulfate) appears to elicit weight loss (in trials of 1-12 months duration). However, studies of ephedra or Ephedrine (ephedrine sulfate) monotherapy have been equivocal.
