History & Botany

From Australia to New Caledonia : A Tree in the Service of Medicine for Millennia

Niaouli is a large tree native to Australia and New Caledonia, where Pacific populations have used it for millennia as a disinfectant, healing agent, and febrifuge. Its name comes from the Kanak language of New Caledonia. Australian Aborigines used its leaves in poultices for wounds and skin infections; the bark was used for building shelters and canoes.


Discovered by European explorers in the 18th century, it is now cultivated in Madagascar, Australia, and Papua New Guinea. Its essential oil is included in the composition of several French pharmaceutical specialties under the name "gomenol", from the port of Gomen in New Caledonia, from where it was exported. During World War I, its production was requisitioned by military doctors for its exceptional sanitizing properties. In the 20th century, Dr. Valnet made it a reference pulmonary antiseptic.

Morphology

Evergreen tree that can reach 20 to 30 meters in height. Characteristic trunk covered with white, spongy, layered bark, hence its nickname "paperbark tree." This bark allows it to resist fires. Alternate, lance-shaped leaves, intense green, and very fragrant. Dense white flowers in spikes.

Active Ingredients & Biochemistry

A Composition Dominated by Terpene Oxides and Monoterpenols

1,8-cineole (eucalyptol) (40 to 65%) Major molecule. Terpene oxide with powerful anticatarrhal, expectorant, and respiratory anti-infectious properties. Thins bronchial secretions, facilitates their elimination, and sanitizes the airways.
Viridiflorol (6 to 15%) Sesquiterpenol, signature of niaouli. Properties: venous and lymphatic decongestant, anti-inflammatory, and mildly estrogen-like. Responsible for the unique radioprotective property of this oil.
Alpha-terpineol & alpha-pinene Monoterpenols and monoterpenes with complementary antibacterial, antiviral, and immunostimulant properties. Alpha-pinene enhances the bronchodilatory action.
D-limonene Monoterpene with antioxidant properties, skin tonic, and enhancer of the percutaneous absorption of other active molecules.
