## Composition (GC-MS research aggregate)

Based on 22 GC-MS samples from 6 peer-reviewed papers (2018–2026); Moderate evidence base. 76 compounds reported in total. Typical share of the oil (median, with interquartile range):

| Compound | Class | Median % | IQR % | Max % | Papers |
|---|---|---|---|---|---|
| α-pinene | Monoterpene hydrocarbon | 39.4 | 27.05–41.6 | 55.76 | 5 |
| β-pinene | Monoterpene hydrocarbon | 10.02 | 6.31–13.4 | 19.63 | 6 |
| δ-3-carene | Monoterpene hydrocarbon | 10.9 | 6.99–15.25 | 16.6 | 4 |
| limonene | Monoterpene hydrocarbon | 7 | 2.6–9.74 | 14.3 | 5 |
| myrcene | Monoterpene hydrocarbon | 3.41 | 3.05–4 | 4.04 | 5 |
| camphene | Monoterpene hydrocarbon | 2 | 1.05–2.35 | 4.76 | 6 |
| bornyl acetate | Oxygenated monoterpene | 2.28 | 1.52–2.84 | 3.4 | 3 |
| β-caryophyllene | Sesquiterpene hydrocarbon | 1.5 | 1.06–3.52 | 8.4 | 4 |
| γ-cadinene | Sesquiterpene hydrocarbon | 1.86 | 1.68–3.13 | 4.4 | 3 |
| germacrene d | Sesquiterpene hydrocarbon | 1.24 | 0.72–1.5 | 1.75 | 3 |
| terpinolene | Monoterpene hydrocarbon | 0.64 | 0.45–0.97 | 1.45 | 4 |
| caryophyllene oxide | Oxygenated sesquiterpene | 0.7 | 0.5–0.7 | 0.7 | 3 |

Chemotypes seen in the samples: α-pinene (59% of samples), δ-3-carene (23% of samples).

## Key constituents

- **Alpha-pinene** (20-50%) — The dominant monoterpene, giving pine its sharp, resinous forest scent
- **Beta-pinene** — Adds green, woody depth alongside the alpha isomer
- **Limonene** — Contributes a brighter, faintly citrus edge

## How to use it

- **In the diffuser:** 3–5 drops freshens workspaces and shared rooms, cutting through stale or stuffy air.
- **In massage blends:** Small, well-diluted amounts (2–4%) suit blends for tired muscles after activity.

## Safety

- Pine oxidizes with age — store it capped away from heat and light, replace older bottles, and dilute to 2–4% and patch-test before skin use.
- Maximum dermal use: Dilute in a carrier oil for skin.
- Store cool and sealed — oxidised pinene-rich conifer oils are more likely to irritate or sensitise skin.
- Dilute before topical use. Not phototoxic.
- Keep out of reach of children.

## What the research says

- Pine needle oil has been studied for antimicrobial activity in the laboratory, in line with its pinene-rich chemistry. These are in-vitro findings, not health claims. — The Scientific World Journal study (2007) (https://doi.org/10.1100/tsw.2007.36)

## Evidence

- Scots pine needle oil is a coniferous monoterpene oil dominated by α- and β-pinene with δ-3-carene, giving it a fresh, sharp, forest aroma. — The Scientific World Journal study (2007) (https://doi.org/10.1100/tsw.2007.36)

## Frequently asked questions

### What does pine oil smell like?

Crisp, fresh, and unmistakably 'forest' — a sharp, resinous, coniferous scent driven by its high pinene and carene content. It's a classic clean, invigorating aroma.

### Does pine oil go off?

Its pinenes oxidise over time, and oxidised conifer oil is more likely to irritate skin. Store it cool, sealed, and out of light, and replace it if the aroma turns sharp or 'off'.

### Is pine oil phototoxic?

No — pine isn't phototoxic, so there's no sun-exposure restriction. Just dilute it and store it well to prevent oxidation.
