Biochemistry

Main article: Muscimol mushroom

As with other Amanita muscaria, the inzengae variety contains ibotenic acid, and muscimol, two psychoactive constituents which can cause effects such as hallucinations, synaesthesia, euphoria, dysphoria and retrograde amnesia. The effects of muscimol and ibotenic acid most closely resemble that of any GABAergic compound, but with a dissociative effect taking place in low to mid doses, which are followed by delirium and vivid hallucinations at high doses.^{[citation needed]}

Ibotenic acid is mostly broken down into the body to muscimol, but what remains of the ibotenic acid is believed^{[according to whom?]} to cause the majority of dysphoric effects of consuming A. muscaria mushrooms. Ibotenic acid is also a scientifically important neurotoxin used in lab research as a brain-lesioning agent in mice.^[1][2]

As with other wild-growing mushrooms, the ratio of ibotenic acid to muscimol depends on countless external factors, including: season, age, and habitat - and percentages will naturally vary from mushroom-to-mushroom.^{[citation needed]}
