scinet i think you misunderstood joevortex. mimosa hostilis is said to contain its own MAOI, at least they have found ß-carbolines in it but the question would be, is it enough to make it oraly active without any additives? i only know about older traditional cultures that mixed the rootbark-powder with passionfruit-juice (which is also said to contain small amounts of MAOI), i never heard or read about the usage of mimosa hostils alone, though.
