Traditional Use & History

Sage has an ancient reputation - its Latin name 'salvia' derives from 'salvere', to be saved or healed - as a digestive, antiseptic and cognitive tonic. It has official European herbal-monograph use for dyspeptic complaints and excessive sweating, and as a gargle for inflammation of the mouth and throat; modern clinical trials support cognitive-enhancing effects in both healthy adults and people with dementia.[11, 12]

Preparations

Infusion (tea)[11]

Dried leaf steeped in hot water, for digestive complaints or excessive sweating.

Gargle/mouthwash[11]

A stronger infusion used topically for sore throat and mouth inflammation.

Standardised extract (capsule)[12, 14]

The form used in cognitive-function clinical trials.

Dosage

Infusion (tea)[11]

EMA herbal-monograph guidance suggests about 1-3 g dried leaf per cup as an infusion, up to three times daily for digestive complaints, or a stronger preparation used as a gargle. Avoid prolonged or high-dose (essential-oil) use given the neurotoxic thujone content, especially in pregnancy and epilepsy. Educational reference only, not a prescription.

Safety, Cautions & Contraindications

Safety note[11]Caution

The essential oil contains thujone, which is neurotoxic and can trigger seizures in high doses - do not exceed recommended doses and do not take the pure essential oil internally; avoid medicinal doses in epilepsy.

Safety note[11]Caution

Avoid medicinal and essential-oil doses in pregnancy and breastfeeding (thujone; sage may also reduce milk supply). Culinary amounts are safe.

Harvest Readiness

[13]
