| Cascara, in No. 20 powder | 100.00 | | | 20 ounces |
| Glycerin | 20.00 | | | 4 fl. ounces |
| Solution of Potassium Hydroxide | 16.00 | | | 3 oz. 96 min. |
| Distilled Water ... | to 100.00 | | | to 20 fl. ounces |
Moisten the drug with 75 (15 fluid ounces) of the water, set the mixture aside for six hours, then exhaust by percolation with distilled water; next add the solution of potassium hydroxide to the percolate, evaporate the mixture on a water-bath until it measures 80 (16 fluid ounces), then add the glycerin and sufficient distilled water, if necessary, to produce 100 (20 fluid ounces). This preparation is an improvement upon, and more active than, so-called tasteless extracts of cascara, which are made by mixing lime or magnesia with the powdered bark before percolation.
Dose.—2 to 4 mils (1, to 1 fluid drachm).
