Muscimol was first described in 1964 as a constituent
of Amanita pantherina. Muscimol is the
decarboxylated product of ibotenic acid and is
considered to be more psychoactive than it. Some
15 to 20 mg is regarded as a psychoactive dosage
(Muller and Eugster 1965; Ott 1993,446*; Scotti et
al. 1969).
Muscimol is an analog of the neurotransmitter
GABA (gamma amino butyric acid) and docks to
its receptor (Johnston 1971). Kavapyrones (cf.
Piper methysticum) also bind to the same receptor.
Ibotenic acid as well as muscimol were detected
in the urine of people who had eaten fly agaric
mushrooms (Amanita muscaria) about an hour
earlier. An experiment with mice conducted by the
same team of researchers found that the amount of
active constituents in the urine passed by one
inebriated animal was not sufficient to inebriate
another animal (Ott et al. 1975).</td>
