HERBAL ENCYCLOPEDIA
ARNICA Mountain Tobacco Arnica montana, Linn.* Compositae Arnica is mainly noted for its medicinal properties, but is seldom used internally. Though it has stimulant and diuretic properties, it can be an irritant to the stomach and there have been cases of fatal poisoning. It is mostly used externally on bruises, wounds, and swellings. Arnica spreads rapidly by division and can be grown from seeds. The flowers are collected and dried as the bloom and the roots are collected and dried in the fall season. Arnica montana is a European native, but there are several species native to America. The American Indians used an arnica-based salve on stiff muscles and a tincture to gashes or open wounds. This was taught to early colonists. Applications of the tincture on wounds has been very helpful, but it may cause inflammations with repeated usuage. The European species was the variety used as an official drug plant until the mid 1940's. The Amercian variety was then added. Both have been used as pharmaceutical preparations for oral, intravenous, and external use. * System of nomenclature previous to Linnaeus ** System of binomial nomenclature devised by Linnaeus |
