Amanita muscaria - Fly Agaric
"Muscarine is used in the night sweats of phthisis, in a manner similar to the agaricin. Also in diabetes insipidus. Scudder gave as specific indications for the fly agaric, involuntary twitchings of the face, forehead and eyes, pressing pain in the occiput, with a lack of muscular control. It seems indicated in the typhoid conditions where there is tremor and great restlessness, with a desire to get out of bed."
