Preparation.—Formulary number, 174: "Senna; in No. 60 powder, one thousand grammes (1000 Gm.) [2 lbs. av., 3 ozs., 120 grs.]; alcohol, water, each a sufficient quantity. Moisten the senna with three hundred and fifty cubic centimeters 350 Cc.) [11 fl℥, 400♏] of alcohol, pack it firmly in a percolator, and percolate it with alcohol until it is practically exhausted by this menstruum. The alcoholic percolate thus obtained is rejected, and the alcohol may be recovered therefrom by distillation. Then take out the moist powder, dry it, and prepare a fluid extract by the process and menstruum below mentioned: Process A (see F. 135), Menstruum: Diluted alcohol"—(Nat. Form.).
This preparation is intended to carry the laxative qualities of senna without the griping constituents. These are removed by the preliminary percolation by means of alcohol.
