![58 CATHARTICS.^' ^ f# fi/ULtU^, oil, are commonly employed to adulterate olive oil. The best test for ^v^ ascertaining its purity is that of Poutet, adopted in the last edition of the Edin. Phar. ; mix with a twelfth of its volume of solution of nitrate of mercury, prepared by dissolving with a gentle heat |iv. of mercury in fgixss. of nitric acid (density 1380 to 1390) ; if pure it be- comes in three or four hours like a firm fat, without any separation of liquid oil. For ordinary purposes the presence of other fixed oils may be more readily ascertained, by shaking the oil in a bottle half filled, when if it be pure the surface of the oil soon becomes smooth by repose, but if it be adulterated, a number of air bubbles, beads, remain. Therapeutical Effects.—It is seldom given by the mouth as a cathartic, but forms an admirable addition to laxative enemata, in in- flammation or spasms of the intestines, in dysentery, or in irritation of the urino-genital organs. Dose and Mode of Administration.—f§i. to f§ij. by the mouth ; f§ij. to f§iv. in an enema with decoction of barley. ■ \ [Podophyllum, [U. S.] May apple. The rhizome of Podophyllum Peltatum. An indigenous herb belonging to the Natural family Berberidacece, and to the Linnaean class and order Polyandria Monogynia. Botanical Characters.—Root, perennial, creeping, jointed, the radicals at the joint; Stem about [a foot high, smooth, two leaved, flower, white solitary, nodding, growing from the insertion of the petioles. Physical Properties.—The dried root comes in pieces of the thickness of a writing quill, wrinkled, jointed, brown externally, in- ternally of a lighter colour. The taste is first sweetish, and then bit- ter and slightly acrid ; when powdered it has a faint odour, but has no smell when whole. Chemical Properties.—Mr. Hodgson has discovered in Podophyllum a peculiar principle Podophylline. It is in shining, pale brown, scales, having a bitter taste. Therapeutical Effects.—Podophyllum has long been known as an active purgative, and has been much used in some sections of our country. It bears considerable resemblance to Jalap, like it produc- ing free, watery, evacuations, but is thought by some to produce more griping than that article. Dose and Mode of Administration.—In powder gr. x. to 9i. Ex- traction Podophylli U. S. prepared in the same manner as the ex- tract of Cinchona. 1 PoTASSiE acetas, [U. S.] D. L. E. Acetate of Potash. Preparation.—Dub.— Add gradually to any quantity of carbonate of potash prepared from crystals of Tartar, about five times its weight of dis- tilled vinegar of a medium heat; when the effervescence shall have ceased, and the liquor have given off vapours for some time, add by degrees dis- tilled vinegar, until all effervescence shall cease; the dry salt produced by evaporation, is to be liquefied by cautiously raising the heat; dissolve the cooled salt in water, filter and evaporate, until it becomes on cooling a white crystalline mass; keep in well-closed bottles. The London and Edinburgh Colleges direct it to be prepared by dissolving; the former, Ibj. of carbonate of potash in, acetic acid, fgxxvi., and distilled water, fgxij.; the latter, gvij. or a sufficiency of dry carbonate of potash in Oiss. of](https://iiif.wellcomecollection.org/image/b21143602_0110.jp2/full/800%2C/0/default.jpg)
