Aromatic Cascara Fluidextract
»Prepare Aromatic Cascara Fluidextract as follows:
Mix the Cascara Sagrada with the Magnesium Oxide, moisten it uniformly with 2000 mL of boiling water, and set it aside in a shallow container for 48 hours, stirring it occasionally. Pack it in a percolator, and percolate with boiling water until the drug is exhausted. Evaporate the percolate, at a temperature not exceeding 100, to 750 mL, and at once dissolve in it the flavoring agent(s). When the liquid has cooled, add the Alcohol, in which the sweetening agent(s) and oils have been dissolved, add sufficient water to make the Aromatic Fluidextract measure 1000 mL, and mix.
