Botanical Overview
Cowberry (Vaccinium vitis-idaea var. minus) 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
Cowberry has been traditionally used for urinary tract health, pain and inflammation, and nervous system disorders, among other applications.
Urinary tract health.
- 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.
Pain and inflammation.
- Rheumatism
For pain and inflammation, preparations are applied both topically as compresses and taken internally. A warm poultice draws blood to the area and promotes healing, while internal preparations address systemic inflammation.
Nervous system disorders.
- Nervine
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.
