Infusum Gentianae Compositum.—Compound Infusion of Gentian.

Botanical name:

Related entry: Gentiana (U. S. P.)—Gentian

Preparation.—"Gentian, in moderately coarse powder, 1/2 troy ounce; bitter orange peel, in moderately coarse powder, coriander, in moderately coarse powder, of each, 60 grains; alcohol, 2 fluid ounces; water, a sufficient quantity. Mix the alcohol with 14 fluid ounces of water, and, having moistened the mixed powders with 3 fluid drachms of the menstruum, pack them firmly in a conical percolator, and gradually pour upon them, first, the remainder of the menstruum, and afterward water, until the filtered liquid measures a pint"—(U. S. P., 1870).

The following accords with the Br. Pharm.: Infuse, in a closed vessel for 30 minutes, 55 grains each of sliced gentian root and bitter orange peel (cut small), and 1/4 ounce (av.) of fresh lemon peel (cut small) in 10 fluid ounces (Imp.) of boiling distilled water. Strain.

The formula of the U. S. P., 1870, is to be preferred to that of the latter, as it is a more efficient product, and, on account of the alcohol it contains, is much more easily preserved.

Action, Medical Uses, and Dosage.—Stomachic and tonic. Dose, 1/2 to 1 fluid ounce, 3 times a day.
