Niaouli has a slightly sweet, fresh, camphoraceous aroma. Because of its strong antiseptic and antibacterial properties, it is useful during the cold season to treat head and chest colds and can help relieve skin conditions like psoriasis and acne, as well as help quickly heal wounds and burns. As a disinfectant, it is useful for washing wounds, clearing up ulcers, blemishes, acne, boils, cuts, burns, insect bites, and acting as a decongestant on oily skin. Niaouli is also said to help in increasing concentration and clearing the head while lifting spirits.
