Keynotes

Characteristics
Clarke
  • P.
  • amer.
  • , the American Mountain Ash (the British is P.
  • aucuparia), was

proved by Gatchell on himself, a married woman, and two lads. Gatchell's only symptom was

"irritation of the eyes." Another prover had a similar symptom. By far the greatest number were

induced in the woman; though hers were largely confirmed by those of the boys. Neuralgic,

rheumatic, and gouty symptoms were very severe. The emotional balance was disturbed and a

kind of clairvoyance induced. Labour-like or spasmodic pains were frequent—in uterus; in

bladder like prolapse; constrictive at base of lungs and round waist; like spasm of heart; as if left

leg drawn up. Peculiar Sensations are: As if full of cold water; as if stomach full of cold water;

coldness extends up cesophagus under sternum. As if she were outside of herself and could see

into herself. As if rectum were shrunken and dried up. As if left leg drawn up and would never

straighten again. The symptoms were < by moving about (pains and chilliness); < by exposure to

cold.
