Potentiation of ethanol by Coprinus atramentarius in mice

Abstract
Assessment of toxic manifestations and sleeping times in mice shows that the mushroom Coprinus atramentarius potentiates the action of ethanol when administered orally from 3 to 16 hr before a sub-lethal dose of ethanol. Administration of this mushroom 24 hr before, immediately after or 3 hr after the ethanol causes no potentiation. No similar effect was observed with Coprinus comatus.
