OK, I'm talking about a small self experiment with a tiny piece of anadenanthera colubrina rootbark from rumi willka mountain in Ecuador. I was traveling by this place (south Ecuador) a few month ago. I wanted to take with me small vilca trees to transplant into my land in Sauce, region San martin, Peru. I took a few small plants from the ground and discovered that even with one or two years old they have big hard roots that go deep in the ground. The roots have a very thick red bark. I was walking in this vilca forest and I picked a piece of the rootbark from the plants I was carrying. I put it in my mouth and chew it a little bit. Very, very bitter, that could be the high tannins concentration. After 1 minute or so I start to feel this strong tryptamin buzz. For me no doubt possible, this is active and potent (the piece was less than 100mg). At this point I have absolutely no idea of what can be active in it but the effect is definitely different from the effect i know from the seeds. The buzz is warm and with a kind of "strange" mental feeling or best said a mental feeling of strangeness.
Bufo from the seeds never gave me this kind of mental psychedelic distortion. In some occasions it could have blown me away to the point where mental feeling of time and space simply disappear in one flash, in a salvia like effect but never the kind of flow I felt with this small piece of rootbark. The effect had some similarities with LSA but without the depressant effect.
