Preparation.—"Take of lupulin, 4 troy ounces; alcohol, a sufficient quantity. Pack the lupulin in a cylindrical percolator, and gradually pour alcohol upon it, until 2 pints of tincture are obtained"—(U. S. P., 1870).
Action, Medical Uses, and Dosage.—Lupulin is the active principle of hops, and as the quantity of it varies in different specimens of hops, a tincture of it is decidedly preferable to one made of hops. It may be employed with advantage in coughs, after-pains, and in all cases where opium is inadmissible. (For further uses, see Lupulinum.) The dose is 1 or 2 fluid drachms, in mucilage, or sweetened fluid of some kind.
