Botanical Overview
Sage (Salvia officinalis) is a flowering plant in the Lamiaceae family. This plant has earned a place in traditional medicine through its consistent therapeutic benefits, recorded across multiple cultures. 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
Sage has been traditionally used for digestive health, respiratory conditions, and fever management, among other applications.
Digestive health.
- Carminative
- Stomachic
- Vermifuge
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.
- Cold
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.
Fever management.
- Fever
Febrifuge preparations are typically administered as hot teas to induce perspiration, which helps the body regulate temperature. The patient is kept warm and encouraged to rest while the herb promotes sweating.
