A tree with a long story

  • The name comes from Latin cedrus, itself from Greek kedros, a catch-all word for several Mediterranean conifers including juniper.
  • Ancient writings link cedar with the gods well before Greek and Roman times; the Egyptians used it for divination, and Greek rituals burned the wood.
  • It was venerated in Asia too, appearing in sanctuaries tended by Japanese monks and in fenced sacred sites in parts of China.
  • It was brought to Europe as a reforestation tree on the slopes of Mont Ventoux, and spread across southern Europe from there.
  • Hardy through snowy winters and tolerant of drought, it grows slowly on deep, chalky, well-drained soil, which is why it turns up in so many public parks.

What it is credited with

  • Aromatherapy describes the oil as astringent, antiseptic and antifungal, and uses it mainly on skin and scalp.
  • Herbal cosmetics credit it with an anti-seborrhoeic and anti-dandruff reputation, for oily hair and oily, blemish-prone skin.
  • Traditional aromatherapy classes it as lymphotonic and draining, and it is popular in massage blends aimed at heavy legs, puffiness and the dimpled look of cellulite.
  • Its warm, grounding smell has given it a reputation as a relaxing oil, used in diffusion or in a chest and solar plexus massage at the end of a tense day.
  • In traditional aromatherapy the oil was also rubbed, well diluted, on the chest and back for the comfort of a winter-weary, tickly throat and stuffy breathing.
  • Cedarwood has a long-standing reputation as an insect deterrent: shavings and cedar-derived substances have been used to keep moths, mites and mosquitoes away from wardrobes and linen.

How to use it

The golden rule comes first: this oil is never applied neat and never used in large amounts. Dilute it to no more than one part oil in five parts carrier, that is roughly a 20% blend at the very most.

Massage blend

  • Mix 1 drop of cedar essential oil into 4 drops of a plain carrier oil (sweet almond, sunflower, jojoba) in the palm of your hand.
  • For the grounding, relaxing use: massage the solar plexus, the soles of the feet and along the spine, slowly, for two to three minutes in the evening.
  • For the draining use: massage one area at a time, working upwards from ankle to thigh, once or twice a day for a week or two, then pause.
  • For chest comfort in cold weather: a thin film over the upper chest and upper back, morning and evening, for a few days only.
  • Do a patch test on the inner forearm first and wait 24 hours before using a new blend more widely.

Oily hair and flaky scalp

  • Add 2 to 3 drops to a single dose of shampoo in your hand, not to the whole bottle.
  • Lather, leave one minute, rinse thoroughly, then massage the scalp with your fingertips for a minute.
  • Use it in one wash out of two or three, for a few weeks, rather than every single day.

Scenting and diffusion

  • A few drops in a diffuser for 15 to 20 minutes in a ventilated room fills the space with a dry, woody, fireside smell.
  • Two drops on a scrap of untreated wood or a cotton pad, tucked into a wardrobe, is the old-fashioned moth deterrent.
  • Avoid diffusing around babies, young children, pets and anyone with a sensitive chest.

Frequently Asked Questions

The one thing to remember: one drop of cedar essential oil in four drops of carrier oil, massaged in, is the safe everyday way to use it.

Can I put Atlas cedar essential oil on my skin undiluted?

No. It must always be diluted in a carrier oil, to no more than one part in five. Used neat or in large amounts it can cause skin rashes and other unwanted reactions. Patch test any new blend on the inner forearm and wait a day.

How do I use it for oily hair?

Add 2 to 3 drops to a single dose of shampoo in your hand, lather, leave a minute and rinse well, then massage the scalp with your fingertips. Herbal cosmetics credit the oil with an anti-seborrhoeic and anti-dandruff reputation. Use it every second or third wash rather than daily.

Who should avoid it completely?

Pregnant and breastfeeding women, children under 10, and anyone subject to epilepsy. People on regular medication or with a long-term condition should ask a healthcare professional before using it. It should not be swallowed, and any internal use needs a qualified therapist’s supervision.

What does it smell like, and what does it blend with?

Warm, dry and resinous, with a honeyed pencil-shaving note that most people find grounding. It pairs well with lavender, cypress, bergamot and rosemary in a massage oil. In a diffuser, 15 to 20 minutes in an aired room is plenty.

Is it really useful against moths?

Cedarwood has a long-standing reputation as an insect deterrent, and substances drawn from the tree have been used against moths, mites and mosquitoes. Two drops on a piece of untreated wood or a cotton pad in the wardrobe is the traditional trick. Refresh it when the scent fades.
