The course of poisoning caused by all the three species is substantially the same: nausea is experienced between half an hour and three hours after consumption, accompanied by vomiting, headache, quickened heartbeat, and a persistent dilation of pupils occasionally leading to vision disturbances.
Often the condition of the affected person resembles alchoholic intoxication: the patient becomes talkative, shouts obscenities, sometimes laughs or weeps, strikes himself and keeps on running to and fro. The states of excitement may be dangerous for the sick person and must therefore be mitigated.
Subsequently the patient faints, recovers from time to time, hallucinates, screams, defends himself against invisable danger, etc, but finally falls into a profound sleep from which he usually awakens into a normal state, without remembering his previous behaviour. This poisoning comes to it's fortunate end on the second or third day. First aid consists in the stimulation of vomiting and in taking the patient to hospital; he must be
given neither milk nor alchohol.
The treatment starts with a stomach rinse, the excitement is controlled by remidies of the cholpromazine type, physostigmne (never atropine!) is administered as an antidote against mycoatropine.
