I saw a documentary on this about 3 months ago. It is a catus
that the natives use as a appetite suppressant. It is supposed to be
really good, if you can get the real thing. I got the impression that
one of the large american drug companys was trying to develope
a synthetic version to sell over the counter since the plant is native to
Africa(I Think), and in limited supply I haven't seen any ad's yet. I would be willing to give it a go.
