Read on to learn more about eucalyptus oil and how you can apply its benefits to everyday well-being.

History & Origins of Eucalyptus Oil

Native to Australia and mainly noted as being the preferred food source of koala bears, the use of eucalyptus leaves by Australian Aborigines has been recorded. These people used the oil-containing leaves as a traditional medicine for a multitude of ailments such as fever, pain, wounds, infections, and respiratory illnesses.

Learning such uses from the Australian natives, a story has it that an early English settler used eucalyptus leaves to bandage his stitched thumb, which was nearly severed by an ax. A doctor who later treated the man was amazed at how well the wound had healed, and remarked at how there was no sign of infection whatsoever.

Such occurrences caused botanists, scientists and pharmacists to study the various species and parts of the eucalyptus tree in the late 1700’s, with an interest in the potential healing effects that its leaves contained. Many experiments yielded promising results, leading to the eventual extraction of the oil.

Its reputation spread in various countries such as Germany, England and the US. Soon after, eucalyptus oil was being used in hospitals and homes to treat respiratory ailments like bronchitis, coughs, asthma and flu. Its antiseptic properties also served well for treating skin ailments like wounds and burns, and for cleaning hospital apparatus like urinary catheters.

In Europe, the original eucalyptus oil introduced was extracted from the Eucalyptus peperita species, and was known as “Sydney peppermint.” It was remarked to be more effective than the more well-known peppermint oil at that time for respiratory ailments, as it was “less pungent and more aromatic,” and was able to relieve congestion more quickly.

Even scientists from China and India took to studying the oil. In Traditional Chinese Medicine, eucalyptus is an excellent remedy for promoting breathing and “clearing lung-phlegm.”

Eucalyptus takes its name from the Latin words “eu” meaning “well,” and “calypto” meaning “concealed or covered.” This refers to the flower of the eucalyptus tree, which is covered by a tiny cap before budding.

Today, eucalyptus trees can be found in many different countries for various purposes. Yet its main value lies in its essential oil, where simply rubbing two leaves together will give you that pungent, cooling aroma reminiscent of a refreshing gush of air.

Source and Composition of Eucalyptus Oil

Eucalyptus oil is extracted from the fresh or partially-dried leaves of the eucalyptus tree, also known as “blue gum tree” or “fever tree.” There are many species of eucalyptus, but this camphoraceous oil is obtained in particular from Eucalyptus globulus of the plant family Myrtaceae.

This colorless aromatic oil is obtained from the tree’s oval-shaped leaves using steam distillation. It contains over a hundred different compounds, including 1,8-cineole, pinene, limonene, and terpineol. Its main constituent is 1,8-cineole, also known as eucalyptol, and is responsible for most of the oil’s useful healing and antiseptic properties.

The tall, evergreen, eucalyptus tree was originally native to Australia, but today is grown all over the world for its valuable essential oil.

What are some Benefits of Eucalyptus oil?

Be it for treating skin problems, respiratory ailments or simply getting your home clean and fresh, a bottle of eucalyptus oil is a must-have. In aromatherapy, its cooling and cleansing properties have associated it as an herb of purification. This may be true, as eucalyptus oil’s antiseptic and disinfectant properties can kill off disease-causing microbes during infections and chase away nasty molds and germs from any surface in the home.

Eucalyptus oil’s wide range of beneficial effects is due to its active component, cineole, which has been studied extensively. Even now, its astounding potential in killing off leukemia cells is being further investigated.

It is commonly useful in congestion and relief of respiratory conditions, and can also help boost immunity and circulation.

3.) It helps in relieving cough and colds

A nasty cough and cold can easily be soothed by eucalyptus oil’s cool, menthol-y scent, which is the trademark scent in a lot of vapor-rub formulations. This is because of the oil’s expectorant properties, whereby it loosens up mucus and phlegm for you to more easily cough up or expel. The best ways to use the oil for this purpose are as a rub on the chest or breathing in the oil using a diffuser. You can also rub a few drops between your palms and cup your hands over your nose for easy inhalation. Alternatively, a steam inhalation session containing eucalyptus oil also makes for an effective remedy. Simply pour a cup or two of boiling water onto a bowl or small wash basin. Mix in 10-12 drops of eucalyptus oil, and inhale the vapors deeply with a towel draped over your head. When doing this, be sure to keep your eyes closed as the oil’s cooling effect can make your eyes sting a bit.

A variety of studies have looked into eucalyptus oil’s effectiveness for asthma relief.

You can use the same methods above for using eucalyptus oil to treat asthma. A side note when using this oil for treating asthma is to first check with your physician before doing so, as some anti-asthma medications do not interact well with eucalyptus oil. Also, this oil is not meant to take the place of anti-asthma medications that your doctor may have prescribed for asthma attacks.

A plus is that it gives a fresh, clean scent to your storage areas.

18.) It works for flea control

If your dog is a walking fleabag but you don’t want to use any of those flea collars or flea powders with harsh chemicals, eucalyptus oil is the answer! The oil is safe for dogs and can safely be added to pet shampoo. Place 3-4 drops on your shampoo mixture and bath your dog the usual way. You can also make an organic flea collar. Get a bandana or a similar piece of cloth, and place 8-10 drops of eucalyptus oil on various spots in the bandana. Fold into a triangle and tie onto your dog’s neck. Voila, you now have a happy, pest-free pet! Note that you may have to replenish the bandana with a few drops of the oil every few days as the oil evaporates into the air over time.

19.) It works like magic as a spot remover

Be it spots on your carpet, clothes, sofa, or other fabrics, eucalyptus oil works as an effective stain remover. Simply mix a small amount of liquid washing detergent with a few drops of eucalyptus oil to make a paste, then dab onto the stubborn stain. Leave this on for about ten minutes, then wash as usual or wipe off the mixture with a wet washcloth if you’re treating larger materials like a carpet or couch. Before trying it on the stain though, be sure to test it first in an unnoticeable area on the item to check that the oil doesn’t react strangely to the fabric you intend to treat. Eucalyptus oil also removes most sticky material that has stuck to fabric like gum, wax and sticky tape. It also helps dissolve heavy oil stains on clothing.

20.) It can be used on head lice

Eucalyptus oil is a great alternative to chemical lice treatments, and can help keep a lice problem at bay. If it works for fleas, then it can be useful for a headful of lice as well. As an all-natural treatment for lice, place several drops of eucalyptus oil diluted with a carrier on hair and scalp. Comb the oil through the hair for a few minutes and leave on. You can repeat this procedure throughout the day, and rinse off the oil after a few applications. You can also opt to leave the oil on the hair overnight and rinse it off the next day.

21.) It can be used to help cool a fever

Eucalyptus oil’s cooling effect can help reduce the discomfort and heat that a fever brings. This is probably one of the reasons why eucalyptus oil is also named “fever tree oil.” Spritzing a few drops on your body can help your temperature cool down a bit. It’s also great as a cooling spray when you simply want a relief from hot weather. Try making our “Eucalyptus-peppermint cooling spray” recipe below for a freshly-scented temperature reducer.

Things to keep in mind when using eucalyptus oil

Eucalyptus oil is generally safe to use, but as with all essential oils, precautions need to be taken to prevent any adverse reactions. The oil should not be taken by mouth except under the supervision of a physician. When used topically on the skin, eucalyptus oil is safe to use. Avoid using the oil or any eucalyptus salve or chest rub on the face and nose for children under the age of two. For babies and small children, its best to avoid using the oil, but if necessary, use only half the adult dose in preparations intended for a child. If you are pregnant, breastfeeding, have hypertension or epilepsy, it’s best to avoid using the oil. If you have any other conditions and are not sure whether it’s safe to use the oil, ask your doctor about this.

If you have sensitive skin, it’s best to do a skin patch test first to check if you are allergic to the oil. When applying directly on the skin, make sure that the oil has been diluted properly with a carrier oil to prevent any burning or stinging. Excessive use of the oil my cause toxic effects on both adults and children. In all cases, avoid getting eucalyptus oil or its vapor in contact with the eyes, lips, and mucous membranes.

Eucalyptus oil is highly flammable, so be sure to keep it away from excessive heat and open flames like stoves and fireplaces. Make sure that it is stored in an area that children and pets cannot access.
