ehpedrine is synthetic. not the plant extract. you can still get the ephedra pills with the plant extract(lipodrene, stimerex, yellow bullets, yada yada) but if its the extract from the leaves and stems - it is no good. you want the ones with the ephedra alkaloid. 32 species of ephedra exist. the basics-ephedra sinica(ma huang) strongest form alkaloid. ephedra viridis-no alkaloid, stems and leaves. there are the originals out there. there is a legitimate sight but they cost a little. if u can find it.
