Aplopappus. Aplopappus (Haplopappus) Baylahuen Remy.—This composite herb is a native of Chili, where it is said to be relied upon as a stimulant in flatulent dyspepsia, and chronic inflammation with hemorrhage of the lower bowels. It has been analyzed by H. H. Rushy (A. J. P., 1890, 488), and later by H. Kahn (A. J. P., 1891, 377). The former found a volatile oil, a fatty oil which had the specific odor of the plant, a brown acid resin of sharp taste, and tannin. The latter determined the percentage of volatile oil as 6.65, and of resin as 21.15. He also considers that this resin is a mixture of four different resins. G. Baille asserts (B. G. T., Feb., 1889) that the remedy is valuable not only in dysentery, but in genito-urinary catarrhs, and also as a stimulating expectorant. Dose, one-half to one tablespoonful (7.5-15 mils) of a strong decoction, one part to five, may be given every two hours; or the fluid-extract, from five to twenty minims (0.3-1.3 mils). It has also been used in tincture form as an application to slowly healing wounds and ulcers.
