Extract of Jabor′and i (Fluid)

(F. V. Greene, ‘Amer. Journ. Pharm.,’ 1877.) Prep. Jaborandi leaves in moderately fine powder, 16 troy oz.; alcohol (50 per cent.), a sufficient quantity. Moisten the powder thoroughly with the menstruum, pack in a conical gla percolator, place a layer of two inches of well-washed sand on the top of the cloth covering the material, add menstruum until the liquid begins to drop from the percolator, when the lower orifice is to be closed with a cork, and the percolator securely covered; set aside in a moderately warm place for four days. At the expiration of this time remove the cork, and add more menstruum by degrees until the material is exhausted. The first 14 ounces (old measure) of the percolate are to be reserved, and the remainder evaporated on a water bath, with constant stirring towards the close, to 2 fluid ounces (old measure), which are to be added to the reserved portion. If the percolation and evaporation have been properly performed the fluid extract will not be required to be filtered.
