Ephedra?

I'm confused about something. What's new, right? As I said yesterday, I was looking at fatburning supplements. That is when I came across Stimerex ES. The website says it contains ephedra extract. I thought ephedra was banned in the United States. So is it OK for them to sell this because it's listed as an 'extract' and not as ephedra itself? That isn't much of a difference, is it? I want to shed a few extra pounds, not risk my life!
