You need to be careful with Ayahuasca to not have MAOI in your diet or medicine. Things like fermented cheese, fish, wine for example can each be dangerous.

Disclaimer: I used Ayahuasca once. If you must use psychedelics, stick to LSD or amanita muscaria / psilos, they are much safer. Its ridiculous Ayahuasca is legally obtainable in The Netherlands, while LSD and psilos are not with the former easy to standardize and the latter being banned for safety reasons (17 y.o. French student committed suicide in Amsterdam after usage).

Have you tried Amanita muscaria? I'm terrified.

Twice, legally bought standardized in powdered form from an online smartshop. I found it less severe than psilos, more mellow, not very visual (but I had difficulty with getting visual hallucinations anyway). At one point I fell asleep and it reached the level of a waking dream. Woke up all sweaty. Back when I did it (around 2005-7), the smartshop had an OK website, and there was Erowid.
