Preparation.—Tincture of Panax.
Dose.—From one drop to half a drachm.
Therapeutic Action.—Ginseng is feebly tonic, a pleasant stomachic and aromatic stimulant, a gentle nervine, slightly diaphoretic, and somewhat demulcent.
It promotes the appetite, facilitates digestion and invigorates the general system, and is considered beneficial in morbid states of the nervous system. Some are in the habit of employing it as a nervine and antispasmodic, either alone or associated with other agents belonging to that class, in cases of debility or irritability of the nervous system.
