b. (P. Cod.) As ALCOHOLIC EXTRACT OF ACONITE.—P. Cod.

c. (Ph. Baden.) As EXTRACT OF FOXGLOVE—Ph. Baden. See Lactucarium.

Extract of Liq′uorice. Syn. Extractum glycyrrhizæ (B. P.), L. Prep. 1. (Soft e. of l.; Extractum glycyrrhizæ molle, L.)—a. (Ph. L.) From fresh liquorice root, as EXTRACT OF HOPS—Ph. L.

b. (Ph. E.) From the fresh root, cut into slices, dried, and powdered, as EXTRACT OF GENTIAN—Ph. E. The form of the Ph. Baden is very similar.

c. (Ph. D.) As ordered for simple extracts (EXTRACTA SIMPLICIORA—Ph. D.).

d. (B. P.) Liquorice root in coarse powder, 1; cold distilled water, 5; macerate the root in half the water for twelve hours, strain, and press; again macerate the pressed marc with the remainder of the water for 6 hours, strain and press, mix the strained liquors, heat to 212° F., strain, and evaporate to a pill consistence.—Dose, 12 to 1 dr.

e. (B. P. Extractum glycyrrhizæ liquidum.) Prep. Liquorice root in coarse powder, 1 lb.; distilled water, 4 pints. Macerate the liquorice with two pints of water for twelve hours, strain, and press; again macerate the pressed marc with the remainder of the water for six hours, strain, and press. Mix the strained liquors, heat to 212° Fahr., and strain through flannel; then evaporate by a water bath until it has acquired, when cold, a specific gravity of 1·160; add to this one eighth of its volume of rectified spirit; let the mixture stand for twelve hours and filter.

f. (U. S. Disp.) Crude liquorice (Spanish juice), q. s. is dissolved in water, and the solution filtered and evaporated. To produce a good article (EXTRACTUM GLYCYRRHIZÆ PURIFICATUM) in this way, the solution should be allowed some hours for defecation, and should not be decanted and strained until quite cold.

Obs. Soft extract of liquorice is often employed as a pill-basis, and the hard extract (Spanish juice, &c.) is used as a lozenge to allay tickling cough. The principal portion of the latter is, however, consumed by the porter brewers and brewers’ druggists. The product of the last formula, evaporated until it is quite solid when cold, and made into small pipes, sticks, or rolls, forms the BEST REFINED LIQUORICE or REFINED JUICE of the shops.
