Savory 1836, p.92: “Tincture of Rhatany. Rhatany-root has long been employed by the Peruvians as an astringent in dysentery; they also used it as tooth-brush to give firmness to the gums and impart a fine red to their lips. In combination with charcoal, in the proportion of one part to three of charcoal, it forms an excellent tooth-powder. The tincture of rhatany has long been recommended, mixed with an equal quantity of rose-water, as an astringent wash for the gums.”
