Thallium. A Rare Metal. Tl. (***A. W. 203.7). Trituration. Solution of the Sulphate.
Clinical
Baldness. Conjunctivitis. Locomotor ataxy. Paraplegia.
Characteristics
*Thallium is a rare metal discovered by Crookes in the residuum left from the distillation of *Selenium and named Thallium from the green it gives in the spectrum (*H. W., xxxiii. 242). It has been experimented with by Lamy and Marme. Some symptoms of *Thal. *sul., which is an energetic poison, are included (and distinguished) in the Schema. The symptoms observed on animals were from the sulphate, with which Lamy experimented (*H. W., xxxiv. 82). Combermale, of Lille, used *Thal. with success in the night-sweats of phthisis, but this treatment had the effect of causing profuse falling of the hair, so serious as to contraindicate its use. Huchard had patients become quite bald in several days. Hansen says *Thal. relieves the violent pains of tabes dorsalis.
Relations
*Thal. belongs to the Lead group of metals, and approaches Plumb. closest in its symptoms. *Compare: Baldness, Jabor., Pilo., Petroleum Baldness and phthisis, Phosphorus
