Salvia is a genus of plants in the mint family, Lamiaceae. It is one of three genera commonly referred to as sage. When used without modifiers, sage generally refers to common sage (Salvia officinalis); however, it can be used with modifiers to refer to any member of the genus. This genus includes approximately 700 to 900 species of shrubs, herbaceous perennials, and annuals with almost world-wide distribution. The center of diversity and origin appears to be Central and South Western Asia.¹ Different species of sage are grown as herbs and as ornamental plants.² The ornamental species are commonly referred to by their scientific name Salvia.

The closely related genera Perovskia and Phlomis are also known as sage. Some species of the unrelated genus Artemisia are also referred to as sages, a shortened version of sagebrush. Smudge bundles are made with various grey-leaved species of Artemisia and are misrepresented as "whitesage" smudges. The true whitesage is Salvia apiana.

Description

Salvia species include annual, biennial, or perennial herbs, and a few woody based sub-shrubs. The stems are typically angled like other members in Lamiaceae. The flowers are produced in spikes, racemes, or panicles, and generally produce a showy display with flower colors ranging from blue to red with white and yellow less common. The calyx is normally tubular or bell shaped, with out bearded throats, and divided into 2 parts or lips, the upper lip entire or 3-toothed, the lower 2-cleft. The corollas are often claw shaped and are 2-lipped with the upper lip entire or notched and spreading. The lower lip typically has 3 lobes with the middle lobe longest. The stamens are reduced to two short structures with anthers 2-celled, the upper cell fertile, and the lower imperfect. The flower styles are 2-cleft. The fruits are smooth nutlets and many species have a mucilaginous coating.

Salvia species are used as food plants by the larvae of some Lepidoptera (butterfly and moth) species including (but not limited to) the bucculatricid leaf-miner Bucculatrix taeniola which feeds exclusively on the genus and the Coleophora case-bearers C. aegyptiacae, C. salviella (both feed exclusively on S. aegyptiaca), C. ornatipennella and C. virgatella (both recorded on S. pratensis).

Classification

The defining character of the genus Salvia is the unusual pollination mechanism which consists of two stamens (instead of four as in other plants in the tribe Mentheae) and the way the two stamens are connected to form a lever. When a pollinator goes into the flower to get nectar, the lever causes pollen to be deposited on the pollinator. When the pollinator withdraws from the flower, the lever returns the stamens to their original position. As the pollinator enters another flower of the same species, the stigma is placed in a general location that corresponds to were the pollen was deposited. It is believed that this is a key factor in the speciation of this large group of diverse plants.³ However, it now appears that somewhat different versions of this lever mechanism have evolved several times in the tribe Mentheae, and that Salvia is not monophyletic.⁴⁵

Cultivation and uses

History

The sage species used as herbs come from the Mediterranean and Asia Minor.

The genus name Salvia is derived from the Latin salvare, meaning “to heal” or “to save”.⁶

Sages are also used by several Native American cultures.

Medicinal uses

Several types of Salvia are used medicinally:

• aromatic varieties (usually strongly scented leaves, also used as herbs)
• non-aromatic varieties (not considered medicinal, but many still have a scent)
• Chia sages
• S. divinorum (Diviner's sage) contains a diterpenoid used for spiritual and recreational purposes.
• Research has shown that Salvia officinalis improves cognitive function in Alzheimer's disease patients over a period of several months.⁷⁸⁹¹⁰

The aromatic sages strengthen the lungs and can be used in teas or tinctures to prevent coughs. Less aromatic species of Salvia are run-of-the-mill mint-family anti-inflammatories, which means that they can be used for pretty much any infection or inflammation, and will give at least some relief.

Common sage (Salvia officinalis) drunk as a cold tea will stop sweating, while the same tea drunk hot will produce sweating. Cold and hot teas will also either stop or enhance milk production. The essential oil is used in aromatherapy and medicine.

White sage (Salvia apiana) is a very strong general anti-inflammatory, used as tea or tincture. The tincture has a very nice scent and can be used as a perfume. This species is the famous whitesage of smudge sticks.

Pineapple sage (Salvia elegans, old: S. rutilans) is a tender perennial with pineapple-scented leaves. Medicinally, this is perhaps closest to the scented geraniums, a sweet-smelling Pelargonium species.

Red sage (Salvia miltiorrhiza) is used medicinally in Traditional Chinese medicine.

Chia sages. The seeds of these species are used as bulk laxatives, much like the seeds of Psyllium (Plantago spp.) or linseed. Chia has been important in the diet of desert Indians. It is still used for its mucilaginous qualities by Mexican natives.

Diviner's sage (Salvia divinorum) also called Yerba de la Pastora or sometimes just Salvia, is a plant that differs from all the other sages. It is a Mexican visionary herb and there is some evidence it is a true cultivar. It is known to have strong psychoactive (specifically psychedelic) properties.
