Uses
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.
In Britain sage has for generations been listed as one of the essential herbs, along with parsley, rosemary and thyme (as in the folk song "Scarborough Fair"). It has a savoury, slightly peppery flavor. It appears in many European cuisines, notably Italian, Balkan and Middle Eastern cookery. In British and American cooking, it is traditionally served as sage and onion stuffing, an accompaniment to roast turkey or chicken at Christmas or Thanksgiving Day. Other dishes include pork casserole, Sage Derby cheese and Lincolnshire sausages. 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.
