Wintergreen (Gaultheria procumbens)

Wintergreen (Gaultheria procumbens) is a low-lying evergreen shrub, reaching about 6 in (15 cm), with oval leathery leaves, small bell-shaped flowers, and bright red berries. Known primarily for its oil containing methyl salicylate—a natural anti-inflammatory and analgesic compound—it has long been used for topical pain relief.

Analgesic & Anti-Inflammatory: Methyl salicylate in the oil is effective for muscle, joint, and nerve pain; used in liniments and ointments. Traditional Internal Use: Historically taken as a tea for back pain or rheumatism, though less common now. Aromatic & Cooling: The herb soothes local inflammation and pain; often employed in sports rubs and chest balms.

Essential Oil (Topical Only): Undiluted, it can trigger dermatitis; do not ingest. Aspirin Sensitivity: Those allergic or sensitive to aspirin should avoid wintergreen (it contains salicylates). Children: Exercise caution applying the oil topically to young children (under professional advice).

Indigenous to North American woodlands and mountainous regions, wintergreen prefers acid, moist soils. Leaves and fruit are gathered in summer. The essential oil is obtained by steam-distilling leaves and small twigs.
