Juniper is a common conifer species that can be found all over North America, Europe, and Asia. It has been a particularly successful species worldwide for its ability to thrive in both hot and cold, wet and dry, and sunny or shaded areas.
The berries are used as a medicine and have a distinctive pine fragrance and flavor. Juniper berries are high in many of the same volatile compounds that can be found in the pine tree and other conifers, and share a similar antimicrobial profile as well.
Juniper is mainly used for urinary tract infections, and for its antimicrobial actions.
New research is suggesting junipers use as a nootropic to enhance memory.
- As a diuretic
- As a tonic for the cardiovascular system (short term or low dose)
- Bacterial infections (topically and internally)
- Cystitis (acute or chronic)
- Gout* Arthritis
- Kidney infection
- Kidney inflammation
- Urinary Antiseptic
What is Juniper Used For?
The berries of juniper are high in antiseptic volatile oils, which makes it useful for microbial infection inclusinding topical and upper respiratory tract infections. It is also a popular urinary antiseptic and diuretic for treating lower urinary tract infections.
Newer use involves junipers antiacetylcholinesterase activity for enhancing memory.
Traditional Uses of Juniper Berry
The British herbal pharmacopeia lists juniper as a diuretic, antiseptic, carminative, stomachic, and anti-rheumatic useful for acute or chronic cystitis, flatulent colic, edema, and rheumatism. It is listed as a topical application for rheumatic pain in the joints and muscles .
It was frequently burned by the ancient Greeks to combat epidemics and was used by both the native Tibetans and Native Americans for ceremonial purposes .
Juniper is also a popular addition to cooking, especially game meat and fish.
Juniper berries and the essential oils are popular in the perfume, aromatherapy, food, and liquor industries .

Juniperus is a genus of conifers, containing between 50 and 67 species. It is a member of the Cupressaceae family or "cypress family" of plants. This family comprises 27-30 genera of mainly monoecious trees and shrubs. The other principal medicinal members of this family is Thuja spp. (incense cedar).
Juniper has a small (5-8mm) fruit with a smooth, dark purple colored, waxy shell. The taste resembles pine and has sweet overtones. .
It can grow up to 12 m tall but is generally much smaller. The berries take roughly 3 years to mature. .
Habitat Ecology, & Distribution:
Juniper is native to Europe, Asia, and North America .
The best Juniper is suggested to come from northern Italy, Austria, Czech Republic, Hungary, Croatia, Serbia, and France .
Harvesting Collection, & Preparation:
When extracting juniper berry, hexane was found to yield a higher amount than both super critical carbon dioxide, and hydrodistillation .
If terpene hydrocarbons are desired, extraction by hydrodistillation is best. If the resin is desired (including long-chain oaraffinic acids, and hexadecanoic acid) then the heaxane or supercritical CO2 is the best extraction method. These methods will also produce a more stable extract. If terpinen-4-ol is desired (diuretic), supercritical CO2 extraction is the best. .
Pharmacology & Medical Research
Juniper berries were found to possess powerful antioxidant activities.
It was shown to have heavy-metal chelating ability, active hydrogen donating ability, and acted as a strong scavenger of hydrogen peroxide, superoxide, and free radicals .
Antiacetylcholinesterase (Nootropic & Anti-Alzheimer's Disease)
Juniper berry (Juniperus communis) volatile oil (via hydrodistillation) was found to inhibit acetylcholinesterase and oxidative damage in the brain (rodent models) after inhalation in a dose-dependent manner . This shows an indication that the inhalation of the volatile oils from Juniperus communis can reduce the development and incidence of Alzheimers and dementia related to the buildup of amyloid-beta plaquing in the brain. More research is needed.
Clinical Applications Of Juniper:
Juniper is reliable as a mild urinary antiseptic for mild cases of urinary tract infection and is showing promise as a new nootropic agent. Its antimicrobial effects are well studied and can be applied both topically and internally.
Do not use if kidney disease or kidney inflammation, or during pregnancy (may cause uterin contractions).
