Also Known As: Salvia officinalis, Sage, Common sage
Salvia officinalis (garden sage, common sage) is a small, perennial, evergreen subshrub, with woody stems, grayish leaves, and blue to purplish flowers. It is a member of the family Lamiaceae and is native to the Mediterranean region, though it has naturalized in many places throughout the world. It has a long history of medicinal and culinary use, and in modern times as an ornamental garden plant. The common name "sage" is also used for a number of related and unrelated species.
Common sage is grown in parts of Europe for distillation of an essential oil, though other species, such as Salvia fruticosa may also be harvested and distilled with it.
As a kitchen herb, sage has a slight peppery flavor. In British cooking, it is used for flavoring fatty meats, Sage Derby cheese, poultry or pork stuffing, Lincolnshire sausage, and in sauces. Sage is also used in Italian cooking, in the Balkans, and the Middle East. It is one of the major herbs used in the traditional turkey stuffing for the Thanksgiving Day dinner in the United States. Despite the common use of traditional and available herbs in French cuisine, sage never found favour there.
Salvia and "sage" are derived from the Latin salvere (to save), referring to the healing properties long attributed to the various Salvia species. It has been recommended at one time or another for virtually every ailment by various herbals. Modern evidence shows possible uses as an antisweating agent, antibiotic, antifungal, astringent, antispasmodic, estrogenic, hypoglycemic, and tonic. In a double blind, randomized and placebo-controlled trial, sage was found to be effective in the management of mild to moderate Alzheimer's disease.
The strongest active constituents of sage are within its essential oil, which contains cineole, borneol, and thujone. Sage leaf contains tannic acid, oleic acid, ursonic acid, ursolic acid, cornsole, cornsolic acid, fumaric acid, chlorogenic acid, caffeic acid, niacin, nicotinamide, flavones, flavonoid glycosides, and estrogenic substances.
Investigations have taken place into using sage as a treatment for Alzheimer's disease patients. Sage leaf extract may be effective and safe in the treatment of hyperlipidemia.
