Botanical Overview
Bearberry (Arctostaphylos uva-ursi) is a flowering plant in the Ericaceae family. Traditional medicine systems have documented several valuable applications for this species, supported by its observed therapeutic effects. The heath family (Ericaceae) includes shrubs and small trees with simple, often evergreen leaves that are typically thick and leathery. The flowers are urn-shaped or bell-shaped with fused petals. Many species grow in acidic soils and form mycorrhizal associations, and several produce berries used in traditional medicine.

Traditional Uses
Bearberry has been traditionally used for digestive health, respiratory conditions, and urinary tract health, among other applications.
Digestive health.
- Ache(Stomach)
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.
- Cough
- 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.
Urinary tract health.
- Cystitis
- Diuretic
Urinary tract applications typically involve drinking the herb as a mild tea, which increases urine production and helps flush the urinary system. It may be combined with other demulcent herbs to soothe irritated tissues.
