The plant of Hepatica americana.—U. S.
Preparation.—Tincture of Hepatica.
Dose.—From five drops to one drachm.
Therapeutic Action.—The Hepatica or Liverwort is said to be tonic, astringent, demulcent, pectoral and deobstruent.
The several species of this plant are not very active remedial agents, notwithstanding the high reputation which they at one time enjoyed. It is feebly tonic, slightly astringent, and somewhat demulcent and pectoral. Its employment has been, to a great extent, empirical; and the high praises bestowed upon it by many botanical physicians, it is believed, are to be received with caution and much allowance.
