There are more than 700 species of Eucalyptus, with most varieties native to Australia. A small number of species are found in adjacent areas such as New Guinea, Indonesia, and The Philippines. Just 15 species occur outside of Australia, and only 9 do not occur in Australia. The Philippines boasts just one species itself, so it’s safe to say most eucalyptus originates from way down under. That said, like most small plants and scrubs, Eucalyptus has found its way around the world over the years and is now cultivated throughout many tropical regions.
Eucalyptus has many benefits and has been of interest to global development researchers for sometime due it being a fast growing source of wood. The trees tend to be very water hungry which has led to some controversy as to environmental impact.
Another main interest is of course its essential oil. Eucalyptus Essential Oil is great for many things, but in aromatherapy it is primarily known for its ability to help with sinus issues, as it causes the release of mucus by stimulating nerve receptors in the mucus membranes. Eucalyptus oil has even shown in laboratory studies to have an antibacterial effect against strains of streptococcus (strep throat). The major constituent of Eucalyptus Leaf is Eucalyptol, or 1,8-cineol, found in the stem of the leaf, which makes up 70% of Eucalyptus Globules, the most common form of Eucalyptus Essential Oil.
