Characteristics
"The Mygale Cubensis, which may be called the Cuban Tarentula, also found in South Carolina and Texas, is a larger spider, of a dark brown colour, less poisonous, and covered with more hairs than the Tarentula Hispanica" (Hering). The chief uses to which Trn. c. has been put are: (1) Carbuncle, even to sloughing; with great prostration and diarrhœa. (2) Intermittent fever, with evening exacerbation. A keynote symptom is "atrocious pains." A case of chorea in a girl of twelve is reported (H. M., March, 1901) cured with Trn. c. 6. The movements were confined to the left side, and occurred chiefly at night, when Trn. c. was prescribed.
