Essential Oil of the Month: Eucalyptus

This native Australian oil is probably the most well-known and often used essential oil after Lavender. Its use is so mainstream that you can find it in just about any grocery store, drug store or even department stores. You may find it in its essential oil form, in cough drops, muscle rubs, chest rubs, soaps or mouthwash.


Why so popular? Because of its refreshing scent and myriad benefits! Along with Lavender, you NEED this essential oil in your cabinet.


Eucalyptus’ properties include analgesic, antibacterial, antifungal, anti-inflammatory, antioxidant, antiseptic, antifungal and antiviral. And those are just the A’s!

Eucalyptus has a vast range of beneficial purposes, some of which are listed below:


  • May relieve nasal congestion and open sinuses

  • Clears the mind and improves focus

  • May relieve headache

  • Helps with athlete’s foot and ringworm

  • Helpful at reducing fevers

  • Stimulates the immune system

  • Helps eliminate airborne bacteria and viruses

  • May help repel insects

  • Eases sore muscle and joint pain

  • May Loosen mucus and clear respiratory complaints such as with coughs and colds

There are hundreds of species of Eucalyptus. While Eucalyptus globulus (aka Blue Gum) is most used and best known, some of its cousins such as Eucalyptus citriodora, Eucalyptus stageriana and Eucalyptus radiata offer similar properties with distinct and different properties of their own.


As far back as 1770, Australian Aboriginal tribes used Eucalyptus in their traditional medicine to treat colds, body aches, fungal infections and to reduce fever. This last use may have earned it the nickname “Fever Tree.” The moniker was probably solidified when Eucalyptus trees, whose roots soak up vast amounts of water, were planted in swamps to drain them during the malaria outbreak, destroying the mosquito’s habitat, thus halting the spread of malaria, or fever. Ultimately, the overall long term health of nearby inhabitants was said to have improved as well.


By the 1870s Eucalyptus globulus oil was being distilled and exported worldwide. Laboratory studies that followed showed that eucalyptus oil contains substances that kill bacteria and possibly some viruses and fungi.*1

By the 1880s, surgeons were using Eucalyptus oil as an antiseptic for cleansing wounds. *2

Eucalyptus oil became popular in World War 1 for use against respiratory infections, especially being valued when it quelled a meningitis outbreak and influenza during the 1919 epidemic.*3


Energetically, Eucalyptus is protective and purifying. It opens in us a space of freedom, “room to breathe,” transmuting a sense of suffocation and opening a pathway to new horizons and self-renewal. Indeed, if Eucalyptus has one message to convey, it is to BREATHE! That’s why you find Eucalyptus in steam rooms and saunas. It’s also why it is perfect for your home diffuser in kitchen, bathroom, or office to cleanse and purify your environment.



For a beautiful diffuser blend to open lungs and sinuses as well as cleanse and freshen air:


3 drops Eucalyptus globulus

3 drops Lavender vera

2 drops Lemon Peel

1 drop Cedar Himalayan

1 drop Rosemary officinalis (optional)


Mix the above recipe in a dark glass bottle. Use 3 to 5 drops of the blend in your diffuser, depending on the size of your room. Inhale, refresh, and BREATHE!

PRECAUTIONS: Never take eucalyptus orally. It can be toxic if taken orally and may interact with several medications, particularly those that are processed by the liver. Always speak with your physician before using eucalyptus or any essential oils, especially if you have an existing medical condition. Not for those who are pregnant, epileptic, or for children under 12 years of age. Not for use with pets.
