Niaouli is a large evergreen tree native to Australia. It has leaves nearly 13 cm long and yellow flowers that develop in narrow clusters at the ends of its branches. Its bark peels easily like paper, earning it the nickname “paperbark.” A close relative of tea tree, it offers a sweeter and more woody aroma. Due to its high content of eucalyptol and monoterpenes in its chemical composition, this essential oil is known for its stimulating properties. It is widely used in the production of cosmetics such as creams, lotions, and soaps, as it cleanses the skin and promotes a healthy complexion. It can also help relax tense areas of the body when used for massage.
