Juniper berry oil: gin-like freshness, massage and what the EMA says

Common juniper in a bottle: what is in the berry oil, how to dose it, what to blend it with and what the European Medicines Agency monograph says about it.

In brief: Juniper essential oil is distilled from the berries of common juniper and smells fresh, peppery and coniferous, a little like gin. For a diffuser 2–3 drops are enough; on the skin use a dilution of 1–2%. The European Medicines Agency does not recommend it during pregnancy, breastfeeding or on the skin of children under 12, and as a conifer it is risky for cats.

Latin name	Juniperus communis (common juniper)
Plant part and extraction	ripe berries (cones), steam distillation (our oil: India)
Main components	α-pinene 24–55%, myrcene 7–22%, sabinene up to 29%, limonene, terpinen-4-ol
Scent	fresh, coniferous, peppery, slightly sweet
Dilution	1–2%: 2–4 drops per 10 ml, 6–12 drops per 30 ml
Safety in one word	not in pregnancy

You know juniper from gin, from sauerkraut and from game, but also from heathland, where it grows as a low prickly shrub. The essential oil from its berries is one of the freshest coniferous oils. It smells cleaner than pine and has a peppery note that other conifers lack.

Juniper oil is also one of the few aromatherapy oils for which an official monograph of the European Medicines Agency (EMA) exists. Thanks to that we know fairly precisely what it has traditionally been used for and when to leave it out. We summarise both below.

Berries or twigs? It matters

Juniper oil is made in two ways: from berries, and from twigs with needles. The berry oil is milder, and it is the one described by the European Pharmacopoeia and the EMA monograph. Our BIO common juniper oil is a distillate of ripe berries (Juniperus communis), which corresponds to the quality the EMA works with.

According to the EMA assessment report, the berry oil contains around 105 components. The most abundant are:

Component	Range in the literature	Ph. Eur. limit
α-pinene	24–55%	20–50%
β-myrcene	7–22%	1–35%
sabinene	1–29%	up to 20%
limonene	2–11%	2–12%
terpinen-4-ol	0.7–17%	0.5–10%

Beware of confusion with the "cedar" oil from Juniperus virginiana, which is botanically also a juniper but smells completely different. The difference is explained in the article cedar oil: which cedar is which.

What to combine juniper with

Lemon, grapefruit and bergamot – gin-like freshness for the diffuser.
Cypress and Himalayan cedar – a dry woody blend.
Lavender and rosemary – massage after sport.
Pine and fir – winter forest, for the sauna.

How to dose juniper oil

Use	Adult dose	Remark
Diffuser	2–3 drops per 100 ml of water	it is pronounced, start with 2
Aroma lamp	3 drops	kitchen, hallway, study
Massage of muscles and joints	2%: 4 drops per 10 ml, 12 per 30 ml	intact skin only
Bath	3–4 drops in a spoonful of carrier oil or cream	35–38 °C, 10–20 minutes, only from 12 years of age
Sauna	2 drops in 1 l of water for pouring over the stones	mix well, never onto the stones directly
Cleaning	5 drops in 500 ml of vinegar solution	shake before each use

For medicinal bath products the EMA states 1–1.5 g of juniper oil per full bath. That is roughly 40–60 drops, and it is a dose for registered medicinal products with an emulsifier, not for a home bath with oil from a dropper bottle. At home 3–4 drops mixed into a carrier are more than enough.

Massage blend after a hike or the gym

Add 6 drops of juniper, 4 drops of lavender and 2 drops of rosemary (2%) to 30 ml of jojoba oil.
Mix and test on the forearm for 24 hours.
Massage into calves, thighs or shoulders after a shower.
Use it a few times a week at most and for no longer than 2 weeks at a stretch. If the pain persists, see a doctor.

Three more blends

Gin and tonic (diffuser): 2 drops of juniper, 2 drops of grapefruit.
Kitchen after cooking (aroma lamp): 2 drops of juniper, 2 drops of lemon.
Forest sauna (1 l of water): 1 drop of juniper, 2 drops of pine.

For cleaning with essential oils we have a separate guide in the article cleanliness without chemicals.

What the European Medicines Agency says

The EMA/HMPC monograph from 2010 classes juniper oil among traditional herbal medicinal products, that is, products whose use rests on long tradition, not on clinical studies. For external use it states an indication as a supplement for minor muscle and joint pain. The internal use that the monograph also describes concerns registered medicinal products with a precise dose, not an essential oil from an online shop. Do not swallow our oil.

The monograph also yields what is essential for safety:

Pregnancy and breastfeeding: safety has not been established, use is not recommended.
Children: use on the skin (bath) is not recommended for children under 12 because of insufficient data.
High blood pressure: use a whole-body bath with caution.
Skin: allergic skin reactions have been reported.
Overdose with internal use may irritate the kidneys. That is why you should never swallow the oil and should keep it out of the reach of children.

Other safety rules

Oxidation: α-pinene, myrcene and limonene oxidise in air into substances that can cause a skin allergy. Use up an opened oil within 12 months and store it closed, in a cool and dark place.
Children: no oils under 3 months, for smaller children only briefly in a diffuser with 1 drop, and on the skin and in the bath only from 12 years of age according to the EMA. The general rules are in the article essential oils and children.
Cats: juniper is one of the conifers that are risky for cats. Do not use it in a room with a cat that cannot leave. More in the article essential oils and pets.
Kidney disease: even though this is external use, consult a doctor if you have serious kidney disease.

How to choose a good juniper oil

Look for the Latin name Juniperus communis and the word "berries" (fructus). Oil from twigs is cheaper and sharper. Beware of "cade oil" (Juniperus oxycedrus), which is a tar oil with a completely different use. You can also grow juniper yourself; see the article juniper in the garden.

In a diffuser for a fresh gin-like scent, in massage blends after sport and for cleaning. The EMA recognises it as a traditional product for external use against minor muscle and joint pain.

Can I use juniper oil during pregnancy?

No. The European Medicines Agency does not recommend use during pregnancy and breastfeeding because safety has not been established.

No oils under 3 months. For smaller children only briefly in a diffuser, and on the skin and in the bath only from 12 years of age.

How does juniper berry oil differ from twig oil?

Berry oil is milder and corresponds to the European Pharmacopoeia. Twig oil is sharper and cheaper. Pěstík sells berry oil.

Is juniper oil safe for cats?

No, as a conifer it is among the oils risky for cats. Do not use it in a room the cat cannot leave.
