Common Name: American Columbo.
Principal Constituents.—Gentiopicrin, gentistic acid, and berberine. (?)
Preparation.—Specific Medicine Frasera. Dose, 5 to 60 drops.
Action and Therapy.—The recent root is reputed cathartic and emetic. When dried it is a simple, mild tonic to be used like the simple bitters. Scudder regarded it as a stimulant to the circulation and to the vegetative functions. Its persistent use in moderate doses is said to have overcome obstinate constipation; like the other simple bitters, it may be of some value in chronic catarrhal dyspepsia. From 5 to 60 drops of Specific Medicine Frasera, well diluted, may be given every four hours.
