dang, apologies, but the parent didn't seem to be taking this on a generic tangent. The OP has a very interesting anecdotal story to tell, related directly to a group of people that take ayahuasca for healing, and I, too, am curious about how it worked for them, specifically.
Uh oh, on a proper reading I see that you're right. Thanks for pointing it out.
I overhastily ascribed the comment to the "western medicine, you mean real medicine?" meme that doesn't belong here. Perils of pattern-matching. Retracted!
