ALTERATIVES.
Alteratives are a class of medicines which in some inexplicable manner, gradually change certain morbid actions of the system, and establish a healthy condition instead. They stimulate the vital processes to renewed activity, and arouse the excretory organs to remove matter which ought to be eliminated. They facilitate the action of the secretory glands, tone them up, and give a new impulse to their operations, so that they can more expeditiously rid the system of worn-out and effete materials. In this way they alter, correct, and purify the fluids, tone up the organs, and re-establish their healthy functions. Alteratives may possess tonic, laxative, stimulant, or diuretic properties all combined in one agent. Or we may combine several alteratives, each having only one of these properties in one remedy. We propose to enumerate only a few alteratives, and give the doses which are usually prescribed; the list which we employ in our practice is very extensive, but it cannot be made available for domestic use.
Mandrake (Podophyllum Peltatum), also called May-apple, is a most valuable alterative. The root is the part used. Dose—Of decoction, one to two teaspoonfuls; of tincture, six to eight drops; of fluid extract, three to five drops; of its active principle, Podophyllin, one-twelfth to one-eighth of a grain.
Poke (Phytolacca Decandra), also called Skoke, Garget, or Pigeon-berry, is a valuable alterative. The root is the part used. Dose—Of decoction, one to three teaspoonfuls; of fluid extract, three to ten drops; of concentrated principle, Phytolaccin, one-fourth to one grain.
Yellow Dock (Rumex Crispus), The part used is the root. Dose—Of the infusion, one to three fluid ounces three times daily; of fluid extract, ten to thirty drops; of tincture twenty to forty drops.
Tag Alder (Alnus Rubra), This is otherwise known as the Smooth, Common, or Swamp Alder. The bark is the part used. It is excellent in scrofula, syphilis, cutaneous and all blood diseases. Dose—Of decoction, one or two tablespoonfuls from three to five times daily; of tincture, one or two teaspoonfuls; of fluid extract, one-half to one teaspoonful; of concentrated principle, Alnuin, one-half to one grain.
Black Cohosh (Macrotys or Cimicifuga Racemosa) The part used is the root. Its other common names are Black Snake-root, or Squaw-root. Black Cohosh is an alterative stimulant, nervine, diaphoretic, tonic, and a cerebro-spinal stimulant. It is a useful remedy. Dose—Of decoction, one-fourth to one ounce; of tincture, ten to fifteen drops; of fluid extract, five to ten drops; of the concentrated principle, Macrotin, one-eighth to one-half grain.
