"But maybe the documentary I saw was biased."

Seems like it.

I did it one time and there was no vomitting and feeling great the day after.

But that maybe was, because the plant that was used was apparently not so strong. So yes, it is from natural plants, that can have very different concentrations. I suppose this is what the documentary means with life threatening poisening? Getting a plant that had a unusual high concentration?

But I never heard of those horror stories from people who do it regulary. (Vomitting is quite normal, though) Otherwise I have limited knowledge in that area, but I do know with mushrooms for example, you can use different ones of the same species to mix them to average out concentration differences. I assume the same can be done with Ayuahasca. But like I said, I would not recommend the commercial retreats anyway.

(I did it when I was invited into a ceremony in a remote place by people who were not frauds)
