Common sage

Common sage (Salvia officinalis) is a small evergreen subshrub, with woody stems, grayish leaves, and blue to purplish flowers native to southern Europe and the Mediterranean region.

It is much cultivated as a kitchen and medicinal herb, and is also called Garden sage, Kitchen sage, and Dalmatian sage. In southern Europe related species are sometimes cultivated for the same purpose, and may be confused with the common sage. Although this plant was the one originally called by this name sage, a number of related species are now also called by it, and are described in more detail in the article on sage.

The uses and benefits ascribed to it are many and varied, and are often shared with related species. Uses of common sage include:

• infusions, which are considered to have a calming effect, to soothe a sore throat and as a digestive agent^{[citation needed]}
• preservative flavourings, for instance of cheese
• as a cooking flavouring, such as in sage and onion stuffing
• as a deodorizer preparation used from the extracts of the herb

Common sage is also grown in parts of Europe, especially the Balkans for distillation of the essential oil, though other species, such as Salvia triloba may also be harvested and distilled with it.

A number of cultivars of the plant exist. The majority of these are cultivated more often for ornament than for their herbal properties. All these are valuable as small ornamental flowering shrubs, and for low ground cover, especially in sunny dry situations. They are easily raised from summer cuttings. Named cultivars include

• 'Purpurascens', a purple-leafed cultivar, considered by some to be strongest of the garden sages,
• 'Tricolor', a cultivar with white, yellow and green variegated leaves,
• 'Berggarten', a cultivar with huge leaves,
• 'Icterina', a cultivar with yellow-green variegated leaves,
• 'Alba', a white-flowered cultivar,
• 'Extrakta', has leaves with higher oil concentrations.
• 'Lavandulaefolia', a small leaved cultivar.

Culinary uses

As a herb, sage is considered to have a slight peppery flavour. In Western cooking, it is used for flavouring fatty meats (especially as a marinade), cheeses (Sage Derby), and some drinks. In 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 flavouring in the English Lincolnshire sausage. Sage is also common in Italian cooking. Sage is sauteed 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.

Modern evidence supports its effects as an antihydrotic, antibiotic, antifungal, astringent, antispasmodic, estrogenic, hypoglycemic, and tonic.[1]. 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.^[1]
