SYNONYM: Fluid extract of broom.
Preparation.—"Scoparius, in No. 60 powder, one thousand grammes (1000 Gm.) [2 lbs. av., 3 ozs., 120 grs.]; diluted alcohol, a sufficient quantity to make one thousand cubic centimeters (1000 Cc.) [33 fl℥, 391♏]. Moisten the powder with three hundred and fifty cubic centimeters (350 Cc.) [11 fl℥, 401♏] of diluted alcohol, and pack firmly in a cylindrical percolator; then add enough menstruum to saturate the powder and leave a stratum above it. When the liquid begins to drop from the percolator, close the lower orifice, and, having closely covered the percolator, macerate for 48 hours. Then allow the percolation to proceed, gradually adding diluted alcohol, using the same proportions of alcohol and water as before, until the scoparius is exhausted. Reserve the first eight hundred and fifty cubic centimeters (850 Cc.) [28 fl℥, 356♏] of the percolate, and evaporate the remainder to a soft extract; dissolve this in the reserved portion, and add enough menstruum to make the fluid extract measure one thousand cubic centimeters (1000 Cc.) [33 fl℥, 391♏]"—(U. S. P.).
Description, Medical Uses, and Dosage.—(See Scoparius). This is a deep olive-hued liquid of the bitter taste and peculiar odor of broom. An unimportant precipitate may fall. This is intended as a diuretic, but is not so active in this respect as the infusion, and is inferior to that preparation. Dose, 15 to 60 minims.
