Overview:Juniper is a small evergreen tree/shrub found naturally around the globe in the cooler climate areas of the Northern Hemisphere. Juniper berries are rich in a pleasant tasting essential oil recognized for its digestive properties. Juniper berry tea is listed in the German Pharmacopoeia as a treatment for dyspeptic complaints including gas, heartburn, indigestion, and flatulence. It is noted by German authorities that the tea is also a powerful diuretic and urinary antiseptic. The diuretic action is thought to be largely due to the tea's content of terpinen-4-ol, a non-irritating terpene. Traditional Use/Benefits/Body Systems:Traditionally used in Herbal Medicine as a diuretic, as a urinary tract antiseptic to help relieve benign urinary tract infections, to help relieve digestive disturbances such as flatulent dyspepsia (carminative), and to aid digestion and stimulate appetite (stomachic).
