I've never heard of that brand, but Eucalyptus globulus is know as the Blue Gum and is grown in plantations in Aus for paper and hardwoods. If it is distilled using the steam method its likely to be pretty good. Depends on what water is used and any pollution on the leaves of the trees. Eucalyptus trees need a dry environment and hot weather to really produce large amounts of oil.
There are soooo many uses for Eucalyptus oil that it would take pages to write about them all.
