Evidence scores (1–10) are computed from the tier of each cited source. “Comparable” means the two scores are within one point. Follow a score to its detailed sources.
Key Constituents
Berry essential oil dominated by alpha-pinene, beta-pinene, sabinene and limonene, giving the characteristic aroma and the antimicrobial activity.
Antioxidant and astringent supporting constituents.
Antioxidant and anti-inflammatory constituents.
Aromatic constituents that drive the diuretic action but are toxic in large amounts.
Photosensitising constituents; the basis for the mild phototoxicity caution.
Pharmacological Actions
Carminative digestive and stomach tonic (bloating, indigestion)
Diuretic - reduces fluid retention/swelling and supports urinary and kidney function (traditionally used for urinary stones); animal studies attribute the effect to inhibition of the renal Na+/K+ pump, raising urine flow

Safety, Cautions & Contraindications
Avoid in pregnancy. Juniper is not recommended during pregnancy (EMA/HMPC, 2023; Health Canada, 2025).Avoid with kidney disorders / serious kidney disease. It’s not recommended if you have kidney disease (EMA/HMPC, 2023; Health Canada, 2025).Adults only (for medicinal use). Use in under-18s is not recommended due to lack of data (EMA/HMPC, 2023).Hydration matters. If you’re using it for urinary “flushing,” you need adequate fluid intake (EMA/HMPC, 2023).Stop and seek help if symptoms look serious. Fever, painful urination, cramps/spasms, or blood in urine = talk to a clinician (EMA/HMPC, 2023).Duration caution. If using it beyond a few weeks, talk to a health professional (Health Canada, 2025).If breastfeeding: ask a health professional first (EMA/HMPC, 2023; Health Canada, 2025).
Duke (2002) rates juniper as + (use with caution), noting diuretic, carminative, and aquaretic activities, primarily at the experimental level (score 1). Traditional use for urinary infections is not supported by strong clinical evidence. The essential oil contains potentially nephrotoxic terpinen-4-ol, and juniper is contraindicated in kidney disease, urinary infections with inflammation, and pregnancy (emmenagogue and potential abortifacient properties). Commission E and PhEur do not recommend medicinal doses for prolonged use exceeding 4–6 weeks (Duke, 2002).
Culinary amounts are safe, but medicinal/seed doses and the essential oil (apiole, myristicin) can be toxic and stimulate the uterus - AVOID medicinal doses of parsley in pregnancy.

Botanical Description
Evergreen coniferous shrub or small tree, often low and sprawling, with sharp, needle-like leaves in whorls of three, each bearing a single white band on the upper surface. The plant is dioecious; female plants bear small, round, fleshy, berry-like cones ('juniper berries') that take two to three years to ripen from green to blue-black.[1]
Biennial herb (Apiaceae), usually grown as an annual, 20-60 cm tall, with a slender taproot. Leaves are bright green and finely divided, either flat or tightly curled ('crisped') depending on variety. In the second year, small yellow-green flowers are borne in compound umbels, followed by small, ridged fruit (the 'seed').[11]
Habitat
Grows on heath, moorland, rocky hillsides and open coniferous woodland on poor, often calcareous soils; one of the most widely distributed conifers, native across the Northern Hemisphere from Europe and Asia to North America.
Native to the central Mediterranean (Sardinia and southern Italy), long cultivated worldwide as a culinary and medicinal herb in gardens and as a field crop.[11]
Harvesting
The ripe, blue-black berry-like cones are hand-picked in autumn, typically in their second or third year of ripening (a mix of ages is often present on the same shrub); leaves and young stems can be gathered through the growing season.
Leaves are picked fresh throughout the growing season; the root (of root-parsley varieties) is lifted in autumn; the seed (fruit) is collected from second-year plants once ripe and dry - it is used mainly in medicinal/aromatic preparations rather than food, given its higher concentration of the toxic essential-oil constituents apiole and myristicin.[11]
Traditional Uses
Juniper berry has a long European tradition as a diuretic and urinary antiseptic for minor urinary complaints, a warming digestive carminative for indigestion and bloating, and a flavouring for gin and other spirits; the leaf and wood have also been burned or used topically for their antimicrobial properties.[1]
Preparations
Comminuted juniper cone berries infused in 150 ml boiling water, 2.0-2.5 g as a single dose 1-3 times daily per the current revision of the EU herbal monograph. Educational reference only, not a prescription.
Steam-distilled from the berries; used in small internal doses for short periods or diluted for topical/aromatic use.
Dosage
The EU herbal monograph gives 2.0-2.5 g of the comminuted cone berries in 150 mL of boiling water as an infusion, 1-3 times daily (single dose 2-2.5 g, daily dose 2.5-6 g), for adults and elderly. Use is limited to short courses - if symptoms persist beyond 2 weeks a healthcare practitioner should be consulted - with adequate fluid intake; contraindicated in severe renal disease and not recommended in pregnancy. Educational reference only, not a prescription.
Culinary amounts of leaf are food-safe; medicinal use should stick to modest infusion amounts (roughly 2-4 g dried leaf or root per cup, a few times daily). Avoid concentrated seed extract or essential oil, which are toxic and uterine-stimulant at higher doses, and avoid medicinal doses entirely in pregnancy. Educational reference only, not a prescription.
