what effect does salvia leaf have on the human body?

Answer 1

There are several plants in the salvia family. Sage, for example. Or Salvia divinorum, a plant used for its psychoactive effects.

Answer 2

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.
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) drank as a cold tea will stop sweating, while the same tea drank 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
