New berries appear on mature trees in the fall, and by spring they ripen to blue.
Because the berries take between two to three years to fully ripen, the same plant can have unripe green and ripe blue berries at the same time. In addition to their use in herbology, the berries are used as a flavoring agent in gin and luncheon meats. The berries nutritional profile and volatile oil make them particularly supportive of the genitourinary system. They contain vitamin C and other nutrients. Each capsule contains 400 mg juniper berries.
