Lemon eucalyptus is a plant native to the Australian continent as well as Madagascar. The Aborigines had in fact always known its powerful antibacterial properties . Lemon eucalyptus was also used to dry out swampy areas in the subtropics.
The aborigines of Australia used the sap of the eucalyptus or “gum tree” in direct application on their wounds in order to accelerate the healing of their wounds . Due to its composition rich in anti-inflammatory active ingredients , lemon eucalyptus is thus traditionally known to calm rheumatic pain .
A little history
Trees with great ecological plasticity, eucalyptus in particular, were able to establish themselves outside Australia, in different areas of the world with similar climates.
In the middle of the 19th century, some eucalyptus species were therefore introduced into southern Europe . The craze is such that the cultivation of eucalyptus on both sides of the Mediterranean Sea borders on true passion.
On the Australian side, the craze took, however in a completely different way, because the colonists, after having cut down the aboriginal people, unfortunately did the same with the trees. This greatly threatened and then destroyed much of the traditional knowledge related to therapeutic eucalyptus trees.
