Eucalyptus globulus, also known as Blue gum or Tasmanian blue gum, is a popular essential oil. It has been used traditionally for years and for good reason.

Eucalyptus Globulus Tree

There are so many species of eucalyptus that we tend to just call them by their Latin binomial, and the oil chemistry is different for each species. E.globulus is native to Tasmania, but is also around the globe. The tree makes good pulp but not lumber, and is considered an invasive species. It grows quickly, displaces other species, and it’s strong allelopathic chemicals (essential oil) can stop undergrowth development. It takes a lot of water and quickly establishes a monoculture and alters the ecosystem. So it’s not great if you’re looking to protect your gardens, but it makes a wonderful essential oil.

Eucalyptus Globulus Essential Oil

Those allelopathic chemicals are Eucalyptus globulus essential oil. They exist to protect the tree. In the case of E. globulus, it allows the tree to repel other species and insects so that it can protect itself and grow. While not ideal necessarily for the gardener with an escaping tree, it is pretty fascinating how the plant uses the essential oil naturally. is high in 1,8-cineole, or eucalyptol, making it a fantastic expectorant. Coughs and colds, and lung support is the key way we use this oil. This is an ancient traditional use of the plant. But the eucalyptol also helps aches and pains, so it is effective for sore muscles and joints, as well as headaches.

 

 

Safety Considerations of Eucalyptus Essential Oil

Because of it’s 1,8-cineole, it’s not recommended on or near the face of children under 6 years. I like to focus on the lung area on the back in this case. Apply diluted to children, or make a chest rub to use on the back.

1,8-cineole can be irritating to the skin, so make sure to dilute the essential oil before applying. A minimum 1:1 recommendation is suggested, but more carrier oil may be needed, especially for children. Start with:

  • 0-1 years: 8 drops carrier oil to 1 drop essential oil. If no reaction occurs, move to 7 drops carrier oil to 1 drop essential oil.
  • 2-6 years: 3 drops carrier oil to 1 drop essential oil. You may need more carrier oil. Add as required.
  • 7-11 years: 1 drop carrier oil to 1 drop essential oil. You may need more carrier oil. Add as required
  • 12+ years: 1 drop carrier oil to 1 drop essential oil. You may need more carrier oil. Add as required. Some may be able to tolerate neat application, however, start always start with dilution.
