Reduce the solids to a moderately coarse (No. 40) powder, moisten this with a sufficient quantity of a mixture of two (2) volumes of alcohol and one (1) volume of water, and percolate it in the usual manner, with this menstruum, until seven hundred and fifty cubic centimeters (750 Cc.) [25 fl℥, 173♏] of percolate are obtained. Add to this the glycerin, and set it aside. Then continue the percolation until the drugs are practically exhausted. Evaporate the new percolate to one hundred and twenty-five cubic centimeters (125 Cc.) [4 fl℥, 109♏], and add it to the reserved portion. Each fluid drachm represents 15 grains of zedoary, 71 grains of aloes, and 3 3/4 grains, each, of the other 2 drugs. Note.—The above preparation is not identical with the Tinctura Zedoariae Composita (also known as Tinctura Carminativa, Tinctura Wedelii), which was formerly official in some continental pharmacopoeias"—(Nat.
