How much Ephedrine is in the Ephedra plant?
Q: How much ephedrine is in 50g ephedra herb?

A: According to this site, the average concentration of ephedrine in ephedra is 1-3%. However, this site states that the total alkaloid content of ephedra is on average 1-3%, and that ephedrine makes up anywhere from 40-90% of those alkaloids. Note that plant sources can have quite varied concentrations of desired components (thus the danger of using untested natural sources for drugs). According to these numbers, 50g of ephedra could contain anywhere from 0 to 1.3g of ephedrine.
