444. SABBATIA.—CENTAURY. (Centaurium, the dried flowering plant of Centaurium Contanrium, N.F.) Three species of this indigenous herb are more or less used in this country as tonic and antiperiodic. These are Sabba'tia angular'is Pursh (American centaury), S. paniculata Pursh, and S. Ellio'tti Steudel (quinine flower); the whole plant of the two first-named species is used, the root of the last-named; they probably all contain the same principle, erythrocentaurin, C₂₇H₂₄O₈. Dose: about 1 dr. (4 Gm.).
