Background

According to the U.S. Department of Agriculture, Melaleuca leucadendron and Melaleuca quinquenervia refer to the same plant.

Cajeput (Melaleuca quinquenervia leucadendron, Melaleuca leucadendron) is a tree native to Australia. Cajeput oil is extracted from the leaves and twigs of the plant. Cajeput leaves may be useful for high blood pressure, herpes simplex, and Helicobacter pylori inhibition. They may also have hypoglycemic effects and may be able to lower blood sugar levels. However, currently there is not enough scientific evidence in humans to support the use of cajeput oil for any indication.

Evidence

DISCLAIMER: These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.

Safety

DISCLAIMER: Many complementary techniques are practiced by healthcare professionals with formal training, in accordance with the standards of national organizations. However, this is not universally the case, and adverse effects are possible. Due to limited research, in some cases only limited safety information is available.

Allergies

Avoid in individuals with a known allergy or hypersensitivity to cajeput. Cajeput pollen is a known allergen and may cause positive skin test reactions. In addition, there is a high cross-sensitivity between cajeput, Paspalum notatum, and Callistemon citrinis pollen.

Side Effects and Warnings

There are very few reported adverse effects associated with cajeput. Nonetheless, use cautiously in patients with diabetes, hypoglycemia (low blood sugar), or high or low blood pressure. Leaves harvested from certain areas of the world may contain carcinogenic (cancer-causing) chemicals.

Pregnancy and Breastfeeding

Cajeput oil is not recommended in pregnant or breastfeeding women due to a lack of available scientific evidence.
