The poisonous fungi, known as Amanita pantherina, can produce hallucinogens which can make you feel depressed and very lethargic. The hallucinogenic compounds found in the mushrooms include, but are not limited to, muscimol and ibotenic acid.
Muscimol and ibotenic acid are found in the body of the mushrooms themselves, and are both natural compounds derived from amino acids. Ibotenic acid is a derivative of tyrosine, while muscimol is a derivative of GABA, an inhibitory neurotransmitter.
A. pantherina is commonly consumed as a wild dried pantherina mushroom, although the species has been cultivated for over 30 years. The mushroom produces its hallucinogenic effects within a few hours of ingestion, and the onset of the effects is delayed for about 2-10 days.
The psychedelic properties are mostly felt after the consumption of a small meal. These mushrooms are found in many European countries, such as Spain and Germany. There have been no reported deaths as a result of the consumption of this mushroom, although one death has been linked to the consumption of LSD.
