Overview

Cajeput oil is produced by steam distillation of fresh leaves of the cajeput tree (Melaleuca leucadendra). Cajeput oil is used in food and as a medicine.

People use cajeput oil for colds and congestion, headaches, toothache, skin infections, pain, and other conditions, but there is no good scientific evidence to support these uses.

Don't confuse cajeput oil with tea tree oil (Melaleuca alternifolia) or niauli oil (Melaleuca viridiflora).

How does it work ?

Cajeput oil contains a chemical called cineole. When applied to the skin, cineole can irritate the skin, which relieves pain beneath the skin.
