Therapeutic Action.—The Coptis acts as a tonic and stomachic. It is a mild, simple, and pure bitter, closely resembling Hydrastis, Columbo, Quassia, Gentian, etc., in its medicinal properties; and it may be used as a substitute for these medicines when they are not at command. It is a valuable tonic and stomachic in dyspepsia. In cases of anorexia, but few if any articles will be found superior to this in promoting the appetite; and but few to exceed it, when the digestive functions are enfeebled, in facilitating their restoration to a normal standard.
