Sometimes ephedra may be in an herbal supplement and it is not even labeled. For example, I was using an herbal diet supplement recently, and the main ingredient was Sida Cordifolia, which actually contains ephedra, but they never indicated this on the label, or put any kinds of medical warnings about ephedra. Typically supplements do not provide cautions or warnings that the consumer would need to know to be intelligent about what they are taking. There's a great deal of tradtional Chinese medicine that is still being practiced in the Orient. The quality issies are also quite variable in other parts of the world.
Regulatory policies are also quite variable.
If they did, they would have to be regulated as a drug. No, I do not. I think that careful study will show that there are benefits to taking some supplements. In that situation, I thin it's important to find out the source of the activity. I think that this could trigger a whole new round of drug discovery.
