The juniper berry comes from an evergreen shrub or tree with dark green to blue-green leaves which grows to 20 feet in height.1,2 The native habitat of the juniper berry is the temperate area of the northern hemisphere in Europe, Asia, and North America.1,2 The dried, mature female cone is called the berry and is blue or reddish in its second year.3 The berry is steam distilled after fermentation or without fermentation to extract the essential oil. The berry and the oil extracts from the berry are the parts used.1
Juniper berry has been used as a diuretic,4,5,6 to battle bad breath5 and to enhance appetite.2 Juniper berries are used as flavoring agents in teas, gin, and alcoholic bitters.1,3 The extracts or oils are used in alcoholic and non-alcoholic beverages, baked goods, candy, frozen dairy desserts, gelatins, meat products, and puddings.1,3
Juniper berry oil is used as a fragrance component in creams, detergents, lotions, perfumes, and soaps.1 It is also used externally to ease discomfort.4
The German Commission E approved the use of juniper dried fruit or oil to relieve dyspepsia, disturbed digestion or indigestion.2,7
