Related entry: Bryonia (U. S. P.)—Bryonia

(Modern shorthand: 1:10 91 %)

Preparation.—"Bryonia, recently dried, and in No. 40 powder, one hundred grammes (100 Gm.) [3 ozs. av., 231 grs.]; alcohol, a sufficient quantity to make one thousand cubic centimeters (1000 Cc.) [33 fl℥, 391♏]. Moisten the powder with one hundred cubic centimeters (100 Cc.) [3 fl℥, 183♏] of alcohol, and macerate for 24 hours; then pack it firmly in a cylindrical percolator, and gradually pour alcohol upon it, until one thousand cubic centimeters (1000 Cc.) [33 fl℥, 391♏] of tincture are obtained"—(U. S. P.). This tincture should preferably be prepared with diluted alcohol, as the bitter principle is soluble in water. The tincture has a bitterish taste, and a brownish-yellow color.

Action, Medical Uses, and Dosage.—(See Bryonia.) The dose of this preparation, for its specific uses, should be small-from a fraction of a drop to 2 drops. By some it is employed as a purgative, in doses of from 20 to 90 drops. It is never used in the latter manner in Eclectic practice.
