Ibotenic acid is a chemical compound that is naturally occurring in the mushrooms Amanita muscaria and Amanita pantherina, among others. Ibotenic acid is a potent neurotoxin that is used as a brain lesioning agent and has shown to be highly neurotoxic when injected directly into the brains of mice.[1]

When ibotenic acid is ingested, a small portion is decarboxylated into muscimol. Ibotenic acid evokes entheogenic effects in human beings at doses in range of 50-100mg.[2] Peak intoxication is reached approximately 2-3 hours after oral ingestion,[3] consisting of one or all of the following; visual distortions/hallucinations , loss of equilibrium, muscle twitching (commonly mislabeled as convulsions), and altered sensory perception. These effects generally last for 6-8 hours, varying with dose.[4]

[edit] Medical Uses

Ibotenic acid is used as a brain lesioning agent in the medical environment. When injected intracranially, ibotenic acid causes the development of lesions of the brain.[5]

[edit] Role in Shamanic Rituals

The ibotenic acid (coupled with other substances such as muscimol) found in Amanita muscaria and Amanita pantherina) is a common factor in shamanic rituals, used as a sacrament, of sorts. Muscimol is excreted in the urine, and there are stories of shamans "reusing" urine for intoxication purposes.[6]
