Parts Used & Where Grown
Juniper, an evergreen tree, grows mainly in the plains regions of Europe as well as in other parts of the world. The medicinal portions of the plant are referred to as berries, but they are actually dark blue-black scales from the cones of the tree. Unlike other pine cones, the juniper cones are fleshy and soft.
How It Works
The volatile oils, particularly terpinen-4-ol, may cause an increase in urine volume.1 According to some sources, juniper increases urine volume without a loss of electrolytes such as potassium.2 Juniper contains bitter substances, at least partly accounting for its traditional use in digestive upset and related problems.
