Hmmmm.. Well I think it's very interested if Ibogaine is also found in plants that grow in the Amazon! Neato..
However, I just did some fairly extensive searching on Becchete and Tabernaemontana Undulata, and other than that Wiki article, which is based off an article out of an issue of National Geographic magazine, I can't find anything.. I've found a few sites that DO reference the plant as part of the family and genus that wiki says it in.. But as far as it containing Ibogaine, or the Becchete thing they're talking about applying.. I can't find a thing. I'm not saying I think it's bogus or anything, but obviously there's not much info on this out there..
And crazy.. Did you read that whole article? It says they apply it to their eyes (ouch!) because the visual effects help them distinguish animals from their surroundings when hunting, and "the effects are reported to be long term lasting days or weeks, not just hours".. And that article is also not the first time I've seen Ibogaine listed as an aphrodisiac in small doses... Hmmmm.. Ideas. Hahaha..
