This week we find out why certain mushrooms contain hallucinogens, plus we ask, how long could you survive by eating your own limbs?
Q. Why do fungi make hallucinogens?
The hallunicogens most commonly associated with fungi are psilocybin/psilocin (tryptamine alkaloids -related to serotonin etc) present in the mushroom (basidiocarp), notably of Psilocybe/Panaeolus spp.
Sorry, better to mention that I posted this question of the week. ;) I'd really like to have some discussion about how common these chemicals are. But mainly of course why fungi do bother to make hallucinogens and how they produced them. Addu, Wed, 31st Oct 2012
Keep in mind that some mushrooms also produce deadly toxins.
There is another concoction of hallucinogens (though not fungi related) made from a brew called Ayahuasca as used by Amazonian tribes. The Banisteriopsis caapi vine contains a monoamine oxidase inhibitor (MAOI) and is mixed with the leaves of dimethyltryptamine (DMT)-containing species of shrubs from the genus Psychotria.
