muscarine is a seriouse muscarinin receptor agonist. causes weird mindset, drooling, a lot of the negative sides described in high dose amanita experiences .I think that blends w the existing effects and creates the big fucking crazy effects.Muscarine is of no importance. Unless you get a shroom with lot of it and die. Trace amounts of it in A. muscaria (named so only cuz it's first shroom were it's found) are less of a concern than ibotenic acid.
Ibotenic acid is neurotoxin that ends up in brain in certain quantity. So some "shaman" eating them raw doesn't say any more than some indian guru chugging mercury without consequences.
IMO it's pretty telling that these experiences happen as you scale up the dose. and yes, i have had wild experiences w deliriant elements when eating a large amount of a single shroom with a bad ratio of compounds.
The ibotenic acid thing is far overblown. I was terrified of it for years - the thing is - all the studies are for in vitro application of ibotenic acid alone to monkey brains. -- Glutamate alone without GABA would produce similar lesioning and damage.
Even if you eat pure ibotenic acid, you have natural GABA, and your liver will make muscimol out of the ibotenic acid quickly. It's most likely not a good idea to IV it, but orally you can take significant amounts of ibo without significant negative effect.
It ends up as a pleasant stimulant that changes over to a relaxing muscimol experience over a few hours. Has a nice zing. The pantherinas have another NMDA compound that adds some nice depth as well.
But IME even massive doses of musc or musc/ibo have not produced a delirious / hallucinatory experience. i STILL feel that muscimol is an S-Tier psychedelic, because in sufficient dose it produces a state very similar to the most
profound LSD or mescaline experiences i have had - total understanding and acceptance of myself, a delusional feeling of sobriety. But without the overwhelming stimulation/body feels.
I HAVE had weird experiences, along with drooling when eating single mushrooms from batches that were much more wild than the extracts I get.
