Fluid Extract of Sumach

Take 4 pints 76 per cent. alcohol, and 1 pound of the recently dried bark of Rhus Glabrum (sumach) in coarse powder. Moisten the powdered bark with sufficient alcohol and let it macerate for 24 hours, then percolate with the remainder of the alcohol, returning the first that passes until it runs clear. Reserve the first 4 clear fluid ounces of tincture, evaporate the remainder to 4 fluid ounces, and set aside. Then percoiate the residuum nearly to exhaustion with hot water, evaporate this aqueous solution to 1/2 pint, then add to it 4 ounces white sugar, evaporate to 8 fluid ounces, and, while warm, mix it with the reserved 8 ounces of tincture to make 1 pint of fluid extract.
