Botanical Overview
Rusty-Leaved Alpenrose (Rhododendron ferrugineum) belongs to the Ericaceae family. While not among the most extensively documented medicinal plants, this species has recorded uses that warrant attention from researchers and practitioners. 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.
