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

Preparation.—"Calumba, in No. 20 powder, one thousand grammes (1000 Gm.) [2 lbs. av., 3 ozs., 120 grs.]; alcohol water each, a sufficient quantity, to make one thousand cubic centimeters (1000 Cc.) [33 fl℥, 391♏], Mix seven hundred and fifty cubic centimeters (750 Cc.) [25 fl℥, 173♏] of alcohol with two hundred and fifty cubic centimeters (250 Cc.) [8 fl℥, 218♏] of water, and, having moistened the powder with three hundred cubic centimeters (300 Cc.) [10 fl℥, 69♏] of the mixture, pack it 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 menstruum, using the same proportions of alcohol and water as before, until the calumba is exhausted. Reserve the first seven hundred cubic centimeters (700 Cc.) [23 fl℥, 321♏] of the percolate. Distill off the alcohol from the remainder by means of a water-bath, and evaporate the residue to a soft extract, dissolve this in the reserved portion, and acid enough menstruum to make the fluid extract measure one thousand cubic centimeters (1000 Cc.) [33 fl℥, 391♏]"—(U. S. P.).
