See also:COLOCYNTH, COLOQUINTIDA Or See also:BITTER See also:APPLE, Citrullus Colocynthis, a plant of the natural See also:order See also:Cucurbitaceae. The See also:flowers are unisexual; the male blossoms have five stamens with sinuous anthers, the See also:female have reniform stigmas, and an ovary with three large fleshy placentas. The See also:fruit is See also:round, and about the See also:size of an See also:orange; it has a thick yellowish rind, and a See also:light, spongy and very bitter pulp, which yields the colocynth of druggists. The seeds, which number from 260 to 300, and are disposed in See also:vertical rows on the three parietal placentas of the fruit, are See also:flat and ovoid and dark-See also: Colocynthein also occurs as such in the drug, together with at least two other resins, citrullin and colocynthiden. Colocynthin has been used as a hypodermic purgative—a class of drugs practically non-existent, and highly to be desired in numberless cases of See also:apoplexy. The dose recommended for hypodermic injection is fifteen minims of a 1 % See also:solution in See also:glycerin. The See also:British Pharmacopeia contains a See also:compound See also:extract of colocynth, which no one ever uses; a compound pill—dose 4 to 8 grains—in which oil of See also:cloves is included in order to relieve the griping caused by the drug; and the Pilula Colocynthidis et Hyoscyami, which contains 2 parts of the compound pill to i of extract of hyoscyamus. This is by far the best preparation, the hyoscyamus being added to prevent the See also:pain and griping which is attendant on the use of colocynth alone. The See also:official dose of this pill is 4 to 8 grains, but the most effective and least disagreeable manner in which to obtain its See also:action is to give four two-See also:grain pills at intervals of an See also:hour or so. In See also:minute doses colocynth acts simply as a bitter, but is never given for this purpose. In See also:ordinary doses it greatly increases the secretion of the small See also:intestine and stimulates its See also:muscular coat. The See also:gall-See also:bladder is also stimulated, and the biliary See also:function of the See also:liver, so that colocynth is both an excretory and a secretory cholagogue. The action which follows hypodermic injection is due to the See also:excretion of the drug from the See also:blood into the alimentary See also:canal. Though colocynth is a drastic hydragogue cathartic, it is desirable, as a See also:rule, to supplement its action by some drug, such as aloes, which acts on the large intestine, and a sedative must always be added. Owing to its irritant properties, the drug must not be used habitually, but it is very valuable in initiating the treatment of See also:simple chronic See also:constipation, and its pharmacological properties obviously render it especially useful in cases of hepatitis and congestion of the liver. Colocynth was known to the See also:ancient See also:Greek, See also:Roman and Arabic physicians; and in an Anglo-Saxon herbal of the 11th See also:century. (Cockayne, Leechdoms, &c., vol. i. p.
