## Composition (GC-MS research aggregate)

Based on 12 GC-MS samples from 12 peer-reviewed papers (2021–2026); Strong evidence base. 58 compounds reported in total. Typical share of the oil (median, with interquartile range):

| Compound | Class | Median % | IQR % | Max % | Papers |
|---|---|---|---|---|---|
| 1,8-cineole | Oxygenated monoterpene | 50.28 | 11.11–65.15 | 78.2 | 10 |
| α-pinene | Monoterpene hydrocarbon | 7.3 | 3.6–11.4 | 18.15 | 9 |
| α-terpineol | Oxygenated monoterpene | 2.29 | 0.56–3.31 | 5.37 | 8 |
| γ-terpinene | Monoterpene hydrocarbon | 2 | 1.11–3.6 | 90.14 | 9 |
| p-cymene | Monoterpene hydrocarbon | 1.97 | 0.97–5.45 | 10 | 6 |
| limonene | Monoterpene hydrocarbon | 1.43 | 1.07–4.15 | 6.9 | 6 |
| terpinen-4-ol | Oxygenated monoterpene | 1.2 | 0.72–1.94 | 2.33 | 7 |
| β-pinene | Monoterpene hydrocarbon | 1 | 0.74–2.39 | 11.4 | 7 |
| α-phellandrene | Monoterpene hydrocarbon | 1 | 0.28–2.58 | 4.8 | 7 |
| myrcene | Monoterpene hydrocarbon | 1.33 | 1.01–1.56 | 1.7 | 5 |
| camphene | Monoterpene hydrocarbon | 0.49 | 0.38–0.73 | 1.01 | 6 |

Chemotypes seen in the samples: 1,8-cineole (58% of samples), spathulenol (8% of samples), γ-terpinene (8% of samples), linalool oxide (8% of samples), aromandendrene (8% of samples), 1,5,5-trimethyl-6-methylene-cyclohexene (8% of samples).

## Key constituents

- **1,8-Cineole (Eucalyptol)** (70-85%) — The dominant compound; responsible for the sharp, camphoraceous, clearing aroma
- **Alpha-pinene** — Adds a fresh, pine-like top note

## How to use it

- **In the diffuser:** 3–5 drops alone, or with peppermint and lemon for a sharper, energizing blend.
- **On skin:** Dilute generously in a carrier oil — this species is strong and can irritate skin or airways.

## Safety

- High in 1,8-cineole — avoid use near the face of infants and young children, and introduce cautiously around anyone with asthma.
- Maximum dermal use: Dilute well before topical use.
- Very high in 1,8-cineole: never apply near the face, nose, or chest of infants and young children — it can cause breathing problems.
- Never ingest; even small amounts can be toxic, especially to children.
- Not phototoxic. Keep out of reach of children.

## What the research says

- 1,8-cineole, the dominant constituent of E. globulus, has been studied for respiratory support — for example a randomized trial in acute bronchitis. Promising but specific to the isolated compound and single conditions, not proof the oil treats illness. — Fischer & Dethlefsen (2013), Cough (https://doi.org/10.1186/1745-9974-9-25)

## Evidence

- E. globulus is the highest-cineole common eucalyptus, overwhelmingly 1,8-cineole — the source of its strong, camphoraceous aroma. — Jerbi et al. (2017), Journal of Essential Oil Bearing Plants (https://doi.org/10.1080/0972060x.2017.1304832)
- Cineole-rich eucalyptus carries a documented safety caution around the faces of infants and young children. — Balacs (1997), International Journal of Aromatherapy (https://doi.org/10.1016/s0962-4562(97)80020-3)

## Frequently asked questions

### How is globulus different from other eucalyptus?

E. globulus (blue gum) is the strongest, highest-cineole type — punchy and camphoraceous. E. radiata is softer and gentler; E. citriodora is lemony. Globulus is the classic 'eucalyptus' smell but the most intense.

### Is eucalyptus globulus safe for young children?

Because it's so high in cineole, never apply it near the face, nose, or chest of infants and young children — it can trigger breathing problems. Keep it out of reach and never let a child ingest it.

### Is eucalyptus globulus phototoxic?

No — it isn't phototoxic. The main precaution is its high cineole content around young children, not sun exposure.
