## Composition (GC-MS research aggregate)

Based on 18 GC-MS samples from 2 peer-reviewed papers (2024–2026); Limited evidence base. 11 compounds reported in total. Typical share of the oil (median, with interquartile range):

| Compound | Class | Median % | IQR % | Max % | Papers |
|---|---|---|---|---|---|
| cis-thujopsene | Sesquiterpene hydrocarbon | 26.9 | 26.9–26.9 | 26.9 | 1 |
| α-cedrene | Sesquiterpene hydrocarbon | 19 | 19–19 | 19 | 1 |
| 1-epi-cubenol | Oxygenated sesquiterpene | 3.8 | 3.8–3.8 | 3.8 | 1 |
| β-elemene | Sesquiterpene hydrocarbon | 1.09 | 1.09–1.09 | 1.09 | 1 |
| γ-selinene | Sesquiterpene hydrocarbon | 0.81 | 0.81–0.81 | 0.81 | 1 |
| α-himachalene | Sesquiterpene hydrocarbon | 0.57 | 0.57–0.57 | 0.57 | 1 |
| δ-amorphene | Sesquiterpene hydrocarbon | 0.56 | 0.56–0.56 | 0.56 | 1 |
| junenol | Unclassified | 0.44 | 0.44–0.44 | 0.44 | 1 |
| α-calacorene | Sesquiterpene hydrocarbon | 0.36 | 0.36–0.36 | 0.36 | 1 |

Chemotypes seen in the samples: β-himachalene (11% of samples), δ-cadinene (11% of samples), 1-epi-cubenol (11% of samples), sandaracopimarinol (11% of samples), cis-thujopsene (11% of samples), 4.5% 6-camphenol (6% of samples), 42.2% himachalol (6% of samples), 7.1% himachalol, 4.4% deodarone (6% of samples), himachalol (6% of samples), abietadiene (6% of samples), β+α-eudesmol (6% of samples), germacrene d (6% of samples), (z)-β-farnesene (6% of samples).

## Key constituents

- **Alpha-cedrene** (25-30%) — One of the two dominant sesquiterpenes; contributes the dry, woody backbone of the aroma
- **Cedrol** (20-30%) — A sesquiterpene alcohol that adds the soft, powdery sweetness cedarwood is known for
- **Beta-cedrene** (10-15%) — Supports the woody depth alongside alpha-cedrene

## How to use it

- **In the diffuser:** 3–5 drops alone for a grounding evening atmosphere, or with lavender at bedtime.
- **On skin:** Dilute to 1–3% in a carrier oil — a frequent addition to scalp and hair-care routines.

## Safety

- One of the gentler oils, with low sensitization risk and no meaningful photosensitivity — still patch-test before regular topical use and keep out of reach of children.
- Maximum dermal use: Dilute in a carrier oil for skin.
- Generally gentle and well tolerated; dilute before topical use as with any essential oil.
- Not phototoxic.
- Keep out of reach of children and pets.

## What the research says

- Atlas cedarwood oil is defined by its himachalene sesquiterpenes; studies have examined its composition and antibacterial activity in the laboratory. These are chemistry and in-vitro findings, not health claims. — Chalchat & Garry (2004), Journal of Essential Oil Research (https://doi.org/10.1080/10412905.2004.9698793)

## Evidence

- Atlas cedarwood is a himachalene-rich oil (β-, α-, and γ-himachalene), chemically distinct from cedrol-dominant Virginia cedarwood. — Chalchat & Garry (2004), Journal of Essential Oil Research (https://doi.org/10.1080/10412905.2004.9698793)

## Frequently asked questions

### Is all cedarwood oil the same?

No. Atlas cedarwood (Cedrus atlantica) is himachalene-rich, while Virginia cedarwood (Juniperus virginiana) is cedrol-dominant. They smell related but differ in chemistry and aroma.

### Is cedarwood oil phototoxic?

No — it's a wood oil with no phototoxic constituents. Dilute it for skin as usual, but there's no sun-exposure restriction.

### What does cedarwood blend well with?

Its warm, grounding wood note anchors citrus, floral, and other conifer oils — a versatile base note in relaxing evening blends.
