Belonging to the Myrtaceae family, Eucalyptus globulus, also known as Tasmanian blue gum, is a tall tree native to Australia that can reach a height of up to 35 meters. It is mainly found in Australia, Chile, China, India, Spain, Portugal, Provence, and Corsica.
Among the more than 800 species and varieties of eucalyptus identified, only a small portion contains exploitable essence and is used in therapy. The young branches of Eucalyptus globulus bear opposite, oval leaves, while older branches have alternate, lanceolate leaves. The flowers, visible in spring, have a calyx in the shape of a quadrangular pyramid topped with a "lid" that detaches during flowering, revealing numerous stamens. The fruits are capsules containing seeds.
This tree is particularly valued for purifying marshy areas (as in Italy) and in the production of paper pulp. The elongated leaves are harvested throughout the summer.
Eucalyptus essential oil is a clear liquid ranging from very pale yellow to light orange-yellow, with a fresh and invigorating scent.
