SYNONYM: Tincture of rhatany.
Preparation.—"Krameria, in No. 40 powder, two hundred grammes (200 Gm.) [7 ozs. av., 24 grs.]; diluted alcohol, a sufficient quantity to make one thousand cubic centimeters (1000 Cc.) [33 fl℥, 391♏︎]. Moisten the powder with two hundred cubic centimeters (200 Cc.) [6 fl℥, 366♏︎] of diluted alcohol, and macerate for 24 hours; then pack it firmly in a cylindrical percolator, and gradually pour diluted alcohol upon it, until one thousand cubic centimeters (1000 Cc.) [33 fl℥, 391♏︎] of tincture are obtained"—(U. S. P.). This forms a strongly astringent, brownish-red tincture, liable to precipitate rhatany-red, and sometimes gelatinizing. Prepare it in small amounts, and keep it in well-filled bottles. Glycerin, as a part of the menstruum, will aid in preserving it.
Action, Medical Uses, and Dosage.—This is useful in chronic diarrhoea, and other cases where an astringent is required. It likewise forms an excellent local application to the gums, where they are tender, spongy, and bleed. The dose is 1 or 2 fluid drachms, in sweetened water or wine, if not contraindicated, 3 or 4 times a day.
