The powder of tin (tin filings) has been used as a vermifuge in cases of lumbricus and taenia.
Trousseau remarks that of all metals after mercury, tin has been in the highest repute as anthelmintic, and many secret vermifuges contain either the finely powdered metal or its sulphide: from 30 gr. to 1/2 oz. have been given in electuary. Alston gave 1 oz. at a time, but severely irritant effects sometimes followed. Professor Stille quotes several authorities in favor of the remedy, and Dr. Graves speaks well of it ("Lectures," ii., p. 248), but it is not now much used, because more dependable medicines have been found. It is supposed to act either mechanically or by disengagement of hydrogen or other chemical effects. Salts of di-stann-ethyl have a strong purgative action (Jolyet and Cahours).
In Epilepsy, Chorea, and allied forms of nerve-disorder, the chloride of tin has been given with benefit, according to the observations of Dr. Schlessinger (Medico-Chirurgical Review, October, 1838, and April, 1846).
In Chronic Skin Diseases, the same physician recommends it both internally and in lotion, but its real value is not ascertained.
