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 ( EXTRACT A 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 pre ; again macerate the pre ed marc with the remainder of the water for 6 hours, strain and pre , mix the strained liquors, heat to 212° F., strain, and evaporate to a pill consistence.— Dose , 1 ⁄ 2 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 pre ; again macerate the pre ed marc with the remainder of the water for six hours, strain, and pre . 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 di olved 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 , .) 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. 2. ( Hard e. of l. , Spanish juice , S. liquorice , Glycyrrhizin , Black sugar ; Extractum glycyrrhizæ simplex , E. g. durum , Succus g. , S. g. spi atus , L.) This is seldom prepared by the English druggists, being principally imported in the dry state from Spain and Italy. That from Solazzi ( Solazzi juice ) is the most esteemed. A great deal of the foreign extract is mixed with fecula, or the pulp of plums, hence its inferior quality. It also frequently contains copper, derived from the boilers in which it is prepared. The extract prepared from the fresh root is usually preferred to the best foreign, as the latter has a le sweet and agreeable taste. Refined juice is prepared by di olving the foreign juice in water, filtering and evaporating. See Liquorice , and above .
