A lot of the physical side effects are inherent to MAOIs - they have crazy interactions with all kinds of stuff present in most people's bodies. (Hence the psychedelic interactions with DMT that produce the "ayahuasca" effects, and hence the long and hard-to-follow list of things to avoid for 1 or more weeks pre-trip.)
There's a reason why MAO inhibitors are so rarely used in psychiatry. High efficacy, but the side effects are nasty to deal with.
Ah but that's working around the 'plant spirit' and all that other stuff, you won't have an 'authentic' or 'real' experience and the hipsterswill laugh at you....
What's the point of the tone of your comment? Some people would find the processed drug to lack the "authentic" experience of what is found in nature. Doubt anyone really cares. Sounds more like a caricature to me.
I'm sneering at people who make themselves sick unnecessarily by drinking random plant-juice with a side-order of woo rather than a proper preparation that would give the same effects without the discomfort or other risks, all in the name of 'authenticity'.
