If you don't trust the FDA, how about the New England Journal of Medicine?

http://www.coloradohealthsite.org/CH...s/ephedra.html

The authors conclude:


"The authors note that the risks of taking ephedra as a dietary supplement are difficult to justify because it has no demonstrated benefit. Unlike vitamins and minerals, ephedra alkaloid supplements are not essential for proper nutrition. People who take these products to increase their exercise capacity or to lose weight place themselves at risk without a substantial likelihood of benefit.
Because of the severity of the adverse events that the authors reviewed and, in particular, the occurrence of events that caused permanent disability and death, they concluded that dietary supplements that contain ephedra alkaloids pose a serious health risk to some users."

The evidence is there, whether you choose to accept it or not is your decision. Nevertheless, at least those reading these posts are aware of the problems and can make their own decisions.
