Abstract

Amanita muscaria is considered to be one of the most remarkable and beautiful mushrooms. It has a red or orange cap covered with small white plaques and its distinctive appearance makes accidental and severe intoxication very rare. Its consumption is sometimes used as a means of suicide or it can be consumed for its psychedelic effects, and in some cases, it can be mistaken for edible species. In this paper, we will discuss a patient who fell into a coma after accidental Amanita muscaria poisoning. Rapid identification of the mushroom allowed the regression of symptoms and discharge from the hospital on the fourth day after consumption.
