Eucalyptus (Eucalyptus globulus) essential oil is one of the most popular essential oils as it’s easy-to-use and very effective. So, what is eucalyptus oil good for? Eucalyptus leaves have a naturally sweet aroma but through proper distillation, the essential oil becomes brisk and camphoraceous, so using a diffuser provides multiple benefits. This essential oil is especially good in salves, muscle rubs and clarifying diffusions. Aura Cacia Eucalyptus Essential Oil typically comes from a village in the Yunnan mountain area of southern China. It was planted in China to reforest the area nearly 100 years ago. Distillers use the small pieces of wood on which the eucalyptus leaves are attached to supply the heat necessary to create the steam for distillation. Note: Usage should be guided by a healthcare practitioner for children under the age of 3.
