Preparation.—"Belladonna leaves, in No. 60 powder, one hundred and fifty grammes (150 Gm.) [5 ozs. av., 127 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.).
Action, Medical Uses, and Dosage.—This tincture possesses all the virtues of belladonna, when prepared from the leaves, recently dried. The dose is from 5 to 10 drops. The imported leaves are of such uncertain strength that a tincture made from the alcoholic extract would be more trustworthy. Its uses are those of belladonna.
