Botanical Overview
Clary Sage (Salvia sclarea) belongs to the Lamiaceae family. While not among the most extensively documented medicinal plants, this species has recorded uses that warrant attention from researchers and practitioners. The mint family (Lamiaceae) includes aromatic herbs and shrubs with square stems, opposite leaves, and two-lipped flowers. Many species produce essential oils in glandular trichomes on their leaves and stems. This family is one of the most important sources of culinary and medicinal herbs worldwide.

Traditional Uses
Clary Sage has been traditionally used for digestive health, respiratory conditions, and nervous system disorders, among other applications.
Digestive health.
- Stomachic
For digestive complaints, the herb is typically prepared as a tea or decoction taken before meals. The bitter compounds stimulate digestive secretions and improve nutrient absorption. Some traditions use the powdered root or leaves in small doses as a stomachic tonic.
Respiratory conditions.
- Catarrh
Respiratory conditions are addressed through steam inhalation of the herb’s vapors or internal use as a warm tea. The hot infusion acts as an expectorant, helping to loosen phlegm and clear congestion. Some traditions combine it with honey for coughs.
Nervous system disorders.
- Spasm
Nervous system support involves taking the herb as a warm tea, often in the evening or before bed. The calming compounds interact with neurotransmitter systems to promote relaxation and restful sleep.
