Eucalyptus has many applications, from purifying skin by removing dirt, to warming, toning, and refreshing skin, to promoting a sense of well-being. It can be diffused to reap its benefits through scent. When diffused, Eucalyptus energizes and creates an uplifting atmosphere. Traditionally, some varieties of Eucalyptus have even been used in mosquito repellent sprays, while others continue to be used to relax with massages and provide soothing feeling.
