Physiological Action.—Hydrastis is an astringent bitter, promotes appetite and digestion, increases the secretions of the gastro-intestinal tract, and the flow of bile. Long used, it deranges digestion and causes constipation. It is an antiperiodic, and a protoplasmic poison, arresting the movements of the white blood corpuscles.
- Therapeutics. Hydrastis is chiefly used as a stomachic tonic, an anti-periodic, a mild astringent, and an antiseptic. In—
- Catarrh,—of the stomach, duodenum, gall ducts, intestine, bladder, uterus, vagina; in gonorrhoea, gleet and chronic nasal catarrh, it is an excellent remedy, both locally and internally.
- Syphilitic Affections, of the mouth, throat and nares,—the fluid extr. locally
- Ulcers and Sores, of unhealthy character,—locally applied.
- Stomatitis, both mercurial and aphthous,—the fluid extract locally.
- Constipation,—when due to deficient intestinal secretion.
- Rectal Fissure and Hemorrhage,—the fluid extract locally.
- Intermittents,—here Hydrastine stands next after Quinine.
- Malarial Poisoning,—the fluid extract with Iron preparations.
