## Composition (GC-MS research aggregate)

Based on 2 GC-MS samples from 2 peer-reviewed papers (2022–2025); Limited evidence base. 32 compounds reported in total. Typical share of the oil (median, with interquartile range):

| Compound | Class | Median % | IQR % | Max % | Papers |
|---|---|---|---|---|---|
| 1,8-cineole | Oxygenated monoterpene | 48.16 | 39.87–56.46 | 64.75 | 2 |
| viridiflorol | Oxygenated sesquiterpene | 9.46 | 7.36–11.55 | 13.65 | 2 |
| α-terpineol | Oxygenated monoterpene | 7.44 | 7.44–7.44 | 7.44 | 1 |
| α-pinene | Monoterpene hydrocarbon | 7.08 | 7.08–7.08 | 7.08 | 1 |
| ledol | Oxygenated sesquiterpene | 2.73 | 1.81–3.64 | 4.55 | 2 |
| caryophyllene oxide | Oxygenated sesquiterpene | 2.23 | 2.23–2.23 | 2.23 | 1 |
| β-pinene | Monoterpene hydrocarbon | 2.04 | 2.04–2.04 | 2.04 | 1 |
| β-caryophyllene | Sesquiterpene hydrocarbon | 1.79 | 1.79–1.79 | 1.79 | 1 |
| terpinen-4-ol | Oxygenated monoterpene | 0.8 | 0.79–0.8 | 0.8 | 2 |
| viridiflorene | Sesquiterpene hydrocarbon | 1.56 | 1.56–1.56 | 1.56 | 1 |
| m-cymene | Monoterpene hydrocarbon | 1.54 | 1.54–1.54 | 1.54 | 1 |
| α-terpinyl acetate | Oxygenated monoterpene | 1.43 | 1.43–1.43 | 1.43 | 1 |

Chemotypes seen in the samples: 1,8-cineole (100% of samples).

## Key constituents

- **1,8-Cineole** (40-60%) — The dominant compound; gives niaouli its fresh, camphoraceous aroma
- **Viridiflorol** (5-15%) — A sesquiterpene alcohol contributing to the softer, sweeter edge versus tea tree
- **Alpha-terpineol** (5-10%) — Adds a mild, lilac-like floral undertone

## How to use it

- **In the diffuser:** 3–5 drops for a clean, camphoraceous scent, especially with citrus or eucalyptus.
- **On skin:** Dilute to 1–3% in a carrier oil — many find it gentler than tea tree for daily use.

## Safety

- For topical use, dilute to 1–3% in a carrier oil and patch-test first.
- Maximum dermal use: Dilute in a carrier oil for skin.
- Cineole-rich: avoid applying near the face or nose of infants and young children.
- Dilute before topical use. Not phototoxic.
- Keep out of reach of children.

## What the research says

- Niaouli oil has been studied for antimicrobial activity in the laboratory, in line with its cineole and viridiflorol content. These are in-vitro findings, not clinical proof of benefit. — JEOR study (2008) (https://doi.org/10.1080/10412905.2008.9700007)

## Evidence

- Niaouli (M. quinquenervia) is a cineole-rich Melaleuca oil with notable viridiflorol — fresher and softer than tea tree, another Melaleuca. — JEOR study (2008) (https://doi.org/10.1080/10412905.2008.9700007)

## Frequently asked questions

### How is niaouli different from tea tree?

Both are Melaleuca oils, but niaouli (M. quinquenervia) is cineole-rich and fresh/clearing, while tea tree (M. alternifolia) is terpinen-4-ol-rich. Niaouli is often described as softer-smelling.

### Is niaouli safe around children?

Because it's cineole-rich, avoid applying it near the faces or noses of infants and young children. Diffuse in a ventilated room and keep it out of reach.

### Is niaouli phototoxic?

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