Species
see List of Salvia species

Salvia is a genus 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 shrubs, herbaceous perennials, and annuals. Different species of sage are grown as herbs and as ornamental plants. The ornamental species are commonly referred to by their scientific name Salvia.

The closely related genera Perovskia and Phlomis are also known as sage; Russian Sage (Perovskia atriplicifolia), native to the Crimea east to Afghanistan and Pakistan, is grown as an ornamental plant, because of its blue-violet sprays of flowers and its adaptability to either sun or part shade. It has a pleasant smell and is also grown as a bee plant, but is not consumed by humans. Jerusalem Sage refers to Phlomis fruticosa and other species of Phlomis.

Some species of the unrelated genus Artemisia are also referred to as sages, a shortened version of sagebrush, which is a more appropriate term for them. They generally taste vile and are not used in food preparation, although many of them are used medicinally. Smudge bundles are made with various grey-leaved species of Artemisia and are misrepresented as "whitesage" smudges. The true whitesage is Salvia apiana, which has a delightful scent when burned.

Salvia species are used as food plants by the larvae of some Lepidoptera species including the (but not limited to) 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).

Cultivation and uses

History

The sage species used as herbs come from the Mediterranean and Asia Minor. Sage has also been grown in central Europe since the Middle Ages.

The name Salvia derives from the Latin 'salveo', which means 'to heal'. Indeed this herb is highly regarded for its healing qualities. An ancient proverb states, "Why should a man die who has sage in his garden?". The ancient Greeks used it to treat consumption, ulcers and snake bites.

The Ancient Romans considered sage to be a sacred herb and followed an elaborate ceremony when harvesting it. A sage gatherer would use a special knife (not made of iron as it reacts with the sage), have to have clean clothes and clean feet and a sacrifice of food would have to be made before he could begin. The Romans would use it for toothpaste; they also believed it to be good for the brain, senses and memory. Template:Fact

The Chinese also were quite partial to this herb. 17th century Dutch merchants found that they would trade one chest of sage leaves for three of their teas [1].

Sages are also used by several Native American cultures.


Medicinal uses

Template:Unreferenced 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
  • Divinorum (Diviner's sage) contains a diterpenoid used for spiritual and recreational purposes.
  • Alzheimer's disease, research has shown that it improves cognitive function over a period of several months [1].

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 properties.
