According to T. F. Allen (Hand-book of Materia Medica, p. 19.), "Agaricus acts energetically upon the circulation, respiration, peristalis and secretion.  It irritates and excites the cardiac filaments of the pneumogastric, causes tonic contractions of arterioles and smooth muscle fibre (intestines, bladder, iris), increases secretions from the salivary glands, liver, pancreas, mucous membranes of intestinal canal, etc., and causes contraction of the pupil and spasms of accommodation.  Paralysis results as a reaction from prolonged spasm or as the primary effect of large doses.  Numerous effects (motor and sensory) may be referred to anaemia of nerve centers (brain and spine), caused by persistent spasm of blood vessels."

From the motor centers we obtain tremors, chorea, convulsions, etc., and from the sensory pain in the spinal cord and nerves, and tenderness of the spine to the touch, especially in the lumbar region.

Agaricus has been found chiefly useful in the treatment of chorea, neuralgia and epileptiform spasms, due to spinal irritation or anaemia. It is especially useful in muscular twitchings of a choreic nature, but where chorea has not fully developed.  The drug is of very little use in true epilepsy. Headaches of those subject to chorea; also when resulting Trom prolonged desk work, and in drunkards. According to T. F. Allen it is an exceedingly valuable remedy in asthenopia from prolonged strain spavin of accommodation (Physos.), twitching of eyes and lids; weakness of the muscles, with swimming of the type; myopia; with chronic choroditis.  Dr. Allen also mentions spasms of the muscles of the pinna of the ear, especially of the attoliens, persistent spasms, so that they attracted attention. (Op. cit.).  Hering recommends Agaricus in the delirium of typhus, and also in delirium tremens. Farrington says that in delirium the drug seems to stand between Stramonium and Lachesis, having some similarities to both. (Clin. Mat. Med., p. 382). Agaricus may be indicated in a primary diarrhoea or dysentery, but its gastro-enteric symptoms are usually asso- ciated with nervous complaints. Neuralgic dysmenorrhea.  Rheumatism.  Spasmodic nervous cough.  Allen says Agaricus is a valuable remedy for irregular tumultous palpitation of the heart, "especially for the irritable heart of tea and coffee drinkers, and of tobacco smokers."  It has proved an excellent remedy, both internally and locally, for chilblains, and complaints from frost-bites.
