Help! What drugs / herbs do you think this dietary supplement contain?
I've been taking the dietary supplement itself inside and outside the Past 2 years to help me maintain my weight. It is not approved by the FDA, and all it says on the package is that it has five Chinese herbs essential. Everything else it is written in Chinese. The symptoms are: excessive loss of the heart, increased frequency of urination, appetite almost complete (NO feeling "HIGH" KIND) Is it really just be high doses of caffeine, if not the herbs? Or any other illegal drug? The reason I'm asking is that now I live in the U.S., and I'd have something that sent me. I do not want my friend or myself in any trouble with the U.S. Customs and I have no certainty as what these pills actually contain. Thanks to those who help answer. 
find a link to the website of this pill is on and will leave know. The most likely contain some kind of ephedrine.
