Ephedra is the natural supplement that Ephedrine comes from. The good stuff back in the day was ephedrine based. Ephedra only became popular after ephedrine by itself became illegal. You could go into a 7-11 and they would have bottles of Mini-Thins on the counter which were straight ephedrine. There was a drink called Razor Ripped which was ephedrine based too. I was in my mid 20's then. That's when I could handle all of that stuff! Made for great workouts!!
