Salvia officinalis (Sage, Common sage, Garden
sage, Kitchen sage, Culinary sage, Dalmatian sage,
Purple sage, Broadleaf sage, Red sage) is a small perennial
evergreen subshrub, with woody stems, grayish leaves, and blue
to purplish flowers. It is a member of the mint family, Lamiaceae. It is native to the Mediterranean region and
commonly grown as a kitchen and medicinal herb or as an ornamental garden plant.
The word sage or derived names are also used for a number of related and
unrelated species. Salvia officinalis has been used since ancient times for warding off
evil, snakebites, increasing women's fertility, and more. The Romans likely
introduced it to Europe from Egypt as a medicinal herb.Theophrastus wrote about two
different sages, a wild undershrub he called sphakos, and a similar
cultivated plant he called elelisphakos. Pliny the Elder said that the latter plant was
called "Salvia" by the Romans, and used as a diuretic, a local anesthetic for
the skin, a styptic, and for other uses. Charlemagne recommended the plant for cultivation
in the early Middle Ages and during the Carolingian Empire it was cultivated in
monastery gardens.Walafrid Strabo
described it in his poem Hortulus as having a sweet scent and being
useful for many human ailments—he went back to the Greek root for the name and
called it Lelifagus.
The plant had a high reputation throughout the Middle Ages, with many sayings
referring to its healing properties and value.
It was sometimes called S. salvatrix (Sage the Savior), and was one of
the ingredients of Four Thieves Vinegar, a blend of herbs
which was supposed to ward off the plague. Dioscorides, Pliny, and Galen all recommended sage as a diuretic,
hemostatic, emmenagogue, and tonic.
Common sage is also grown in parts of Europe, especially the Balkans for distillation of an essential oil, though other species, such as
Salvia
fruticosa may also be harvested and distilled with it.
As an herb, sage has a slight peppery flavor. In Western cooking, it is used
for flavoring fatty meats (especially as a marinade), cheeses (Sage Derby), and
some drinks. In the United States, Britain and Flanders, sage is used with onion
for poultry or pork stuffing and also in sauces. In French cuisine, sage is used
for cooking white meat and in vegetable soups. Germans often use it in sausage
dishes, and sage forms the dominant flavoring in the English Lincolnshire
sausage. Sage is also common in Italian cooking. Sage is sautéed in olive
oil and butter until crisp, then plain or stuffed pasta is added (burro e
salvia). In the Balkans and the Middle East, it is used when
roasting mutton.
The Latin name for sage, salvia, means “to heal". Although the
effectiveness of Common Sage is open to debate, it has been recommended at one
time or another for virtually every ailment. Modern evidence supports its
effects as an anhidrotic, 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.
Caution is indicated when used in conjunction with central
nervous system stimulants or depressants.
