"Cascara Sagrada, in No. 40 powder, one thousand grammes [or 35 ounces av., 120 grains]; Alcohol, two hundred and fifty mils [or 8 fluid-ounces, 218 minims]. Prepare a Fluidextract by Type Process D. Evaporate the aqueous percolate to seven hundred and fifty mils [or 25 fluidounces, 173 minims] and when cold gradually add the alcohol and, if necessary, sufficient water to make the product measure one thousand mils [or 33 fluid-ounces, 6 ½ fluidrachms]." U. S. "Cascara Sagrada, in No. 20 powder, 1000 grammes; Alcohol (90 per cent.), 250 millilitres; Distilled Water, sufficient to produce 1000 millilitres. Exhaust the Cascara Sagrada with the Distilled Water by the percolation process; evaporate the percolate to six hundred millilitres; add the Alcohol previously mixed with one hundred and fifty millilitres of the Distilled Water, or with sufficient to produce the required volume." Br.

This fluidextract is a good preparation, but the aromatic fluidextract is more largely used.

The emodin strength of this and similar preparations of cascara, which has been arbitrarily set by most manufacturers at 1.50 grammes in each 100 mils of the fluidextract, may be estimated by the method of Vanderkleed. and. Ewe (Proc. Pa. Pharm. Assoc., 1913, p. 325.)

Dose, fifteen minims to one fluidrachm (0.9—3.75 mils).
