- About
- Cranberry (Vaccinium macrocarpon) is a small, low-lying evergreen shrub with dark green leaves, pink flowers, and bright red berries. Long valued as a nutritious fruit, cranberries also contain compounds (e.g., proanthocyanidins) that help prevent certain bacteria like E. coli from adhering to the walls of the urinary tract. As a result, cranberry juice or extracts are widely used to prevent and manage urinary tract infections (UTIs). It also provides antioxidants and vitamin C.Uva-ursi is a low-lying evergreen shrub growing to 20 inches tall with long trailing stems, dark green leaves that are glossy on the upper side, bell-shaped pink flowers, and small glossy red berries. The name means 'bear's grape' in Latin, as bears are fond of the fruit. Native to Europe and naturalized throughout the northern hemisphere up to the Arctic, it grows in damp undergrowth, heathland, and grassland conditions. The plant was first documented in The Physicians of Myddfai, a 13th-century Welsh herbal text.
