I don’t agree with some people’s negative evaluation of the Fly Agaric.
I feel that those who experience 'undesirable’ effects from this mushroom have consumed it in a less than optimal fashion (such as eating them fresh), taken too little, or have expectations of the resulting intoxication that are misleading.
I have a friend who has on numerous occasions consumed a tea made from the baked, powdered mushroom cap that has had the gills and stem removed. Only the red membrane, where the majority of the psychoactive constituents are said to be located, is used. Heating is essential to decarboxylate as much ibotenic acid into the more potent and less toxic muscimol as is possible. This, according to him, in sufficient doses (a decoction made from 20-30 dry grams) was quite an intense and fulfilling ‘psychedelic’ experience that has unique characteristics quite unlike those of serotonergic psychedelics such as psilocybin or LSD.
The GABAergic action of muscimol, being inhibitory in nature, is conducive to deep states of meditation and centeredness, because of the resulting diminution of one’s inner monologue, and the inability to retain abstract conceptions. It appears that it is also good in combination with more conventional psychedelics, providing a more centred platform from which to propel oneself into those states.
