Arisaema atrorubens, Blume, Rumphia, i. 97; Arum triphyllum, Linn.; Dragon-root; Indian Turnip; Wake Robin.—A native of the United States of America. Its properties agree closely with Arum maculatum, and, like the latter, it yields a pure white fecula. The tuber is used in the United States as a stimulant to the secretions in chronic bronchial affections, rheumatism, &c, in doses of from ten grains to a scruple. The powder, made into a paste with honey, has been beneficially applied to the mouth and throat of children in aphthae.
