1 DEFINITION
Prepare Licorice Fluidextract as follows (see Pharmaceutical Compounding-Nonsterile Preparations 〈795〉). To 1000 g of coarsely ground Licorice, add about 3000 mL of boiling Purified Water, mix, and allow to macerate in a suitable, covered percolator for 2 h. Allow the percolation to proceed at a rate of 1–3 mL/min, gradually adding boiling Purified Water until the Licorice is exhausted. Add enough diluted ammonia solution to the percolate to impart a distinctly ammoniacal odor, and boil the liquid actively under normal atmospheric pressure until it is reduced in volume to about 1500 mL. Filter the liquid, evaporate the filtrate on a steam bath until the residue measures 750 mL, cool, gradually add 250 mL of Alcohol and enough Purified Water to make the product measure 1000 mL, and mix.
