Common sage is grown in parts of Europe for distillation of an essential oil, although other species such as Salvia fruticosa may also be harvested and distilled with it. The essential oil contains cineole, borneol, and thujone. Sage leaf contains tannic acid, oleic acid, ursolic acid, carnosol, carnosic acid, fumaric acid, chlorogenic acid, caffeic acid, niacin, nicotinamide, flavones, flavonoid glycosides, and estrogenic substances.
Some research has suggested certain extracts of Salvia officinalis and S. lavandulaefolia may have positive effects on human brain function, improving memory and attention. These results have been seen laboratory research and in controlled clinical trials [Source].
