Niaouli is a large evergreen tree widely found in Asian countries. The trees have five-inch long leaves and yellow-tinted flowers that flourish in tight spikes at the ends of the branches. The flakey look of the tree gave it various nicknames such as paperbark or paper bark tea tree, and bottle brush. A relative of Tea Tree, Niaouli has a sweeter, yet woody aroma. Niaouli essential oil has a stimulating aroma due to its eucalyptol content and composition of monoterpenes. It has been used in a variety of cosmetics such as lotions, creams and soaps. Due to its limonene content, Niaouli essential oil may help keep skin looking healthy. It may also be beneficial as part of a relaxing massage.
