the big one

[Trichocereus Panza]

you know a good place to read up on this iboga/ibogaine, i would look it up myself but i dont trust just anything google spews out at me

http://www.erowid.org/chemicals/ibogaine/ibogaine.shtml

Ibogaine is the extract form of the traditional African plant Iboga.

I haven't read much myself, but erowid is always the first place I check, they are pretty reliable.
