Active Ingredients. - These are probably chirettine, C26H48015, a bitter, neutral, resinoid substance, discovered by Hohn (which does not reduce an alkaline solution of a copper salt), and ophelic acid, C13H10 O10. The latter forms a yellowish brown syrup, tasting, at first, sour, and then persistently bitter, having also a peculiar gentianaceous odor.
Physiological Action. - The physiological effects of chiretta are much the same as those of gentian.
Therapeutic Action. - Chiretta is an excellent tonic, and is held in high estimation by the European practitioners in India, who employ it for the same purposes as cinchona when the last-named drug is not procurable. The effects, like those of gentian, appear to be relaxing to the bowels rather than constipating. It strengthens the stomach, obviates flatulency, and diminishes the tendency to acidity. As a stomachic, chiretta appears to be especially serviceable in the dyspepsia of gouty subjects.
