Description Blue juniper is the edible round berry of an evergreen shrub with a distinct, aromatic odor. Traditionally used in northern/central European and Scandinavian cuisine to give a sharp, clear flavor to meats. Juniper is also used to flavor gin and also for sauerkraut. In herbal medicine, juniper berries are most often used as a diuretic. For soap use simply adorn the top of your soaps for a natural beautiful look.
