Other confusions have distinguished the history of this so-called remedy. The species which Linnæus selected as the medicinal sarsaparilla and which he named _Smilax sarsaparilla_, happens to be about the only one of some two hundred species which has never been employed in medicine at all. It is only found in North America and not further south than Virginia. Jamaica sarsaparilla has the reputation of being the best, and that comes from Central America. The sarsaparilla which actually grows in Jamaica is not valued in European markets. The origin of the name of sarsaparilla is not agreed upon. Some authorities attribute it to sarsa--red, and parilla--a little vine. Littré derives it from zarza--a bramble, and Parilla--a hypothetical Spaniard who helped to introduce it. The native Indians call it salsa, and the French follow this origin and call it salsepareille. STRAMONIUM may have been known to the ancients as a poison. Dioscorides included it among the henbanes, and Avicenna is supposed to have described it under the name of the Methel nut. Some species of Datura were frequently used in Eastern countries by thieves and sorcerers to induce delirium and subsequent coma, and the herb had the worst of reputations when Störck, of Vienna, experimented with it first on himself about 1765. In consequence of its action on the brain he gave it in cases of mania and epilepsy, and he and some practitioners who followed him claimed to have administered it in such diseases with much success. Its action as an asthma remedy was, however, a popular Indian tradition which was made known to Europeans through a General Gent about 1802. It had been recommended to him by a native, and he found so much relief from it that he introduced it to Dr. Anderson who was practising at Madras. It was stated that General Gent used it so freely and so frequently that it caused his death. XX FAMILIAR MEDICINES AND SOME NOTES OF THEIR HISTORIES. Morbi, non eloquentia sed remediis, curantur.
