Definition

An oral tablet containing an extract of the plant Salvia officinalis (common sage) with reported antihydrotic, antibiotic, antihypertensive, anti-inflammatory, antioxidant, astringent, antispasmodic, estrogenic, and hypoglycemic properties. The primary biologically active component of common sage appears to be its essential oil which contains mainly cineol, borneol, and alpha- and beta-thujone. In addition, sage leaf contains numerous other substances including tannic acid; resins with oleic, ursonic, and ursolic acids; bitter substances with cornsole and cornsolic acid; fumaric, chlorogenic, caffeic and nicotinic acids; nicotinamide; flavones; flavone glycosides; and estrogenic substances. However, the mechanism(s) of action of common sage in the treatment of various disorders is unclear.
