Eucalyptus is a beautiful, giant tree with aromatic leaves, one that many people are familiar with because of its popular essential oil. Eucalyptus globulus is a tree native to Australia, and it has many other aromatic (and medicinal) relatives. In fact, around 20 different eucalyptus species are aromatic enough to be medicinal, and can be used similarly to E. globulus, with some differences depending on species and chemical profiles. This species, however, is the most commonly used in Western herbalism, and the species we will primarily be discussing.

You can now find towering eucalyptus trees in Southern California and parts of costal Mexico, easily harvestable.
