Is eucalyptus oil flammable?

In this blog post, we will answer the question, “Is eucalyptus oil flammable?”. We will also discuss what eucalyptus oil is, the uses of eucalyptus oil, the flammability of the eucalyptus tree, and how to handle eucalyptus oil safely.

Is eucalyptus oil flammable?

Yes. Eucalyptus oil is flammable. Its flash point is 45.5oC. In hot conditions, evaporated Eucalyptus oil might appear as a blue mist. 

Eucalyptus oil is highly combustible (some trees have been known to combust), and fire spreads quickly. Also, dead branches and twigs can readily catch fire.

After a fire, Eucalyptus flourishes. After the 2003 Canberra Forest Fires, acres of imported tree species died. However, the Eucalyptus trees sprung fresh seedlings within a few weeks.

What is eucalyptus oil?

Eucalyptus oil is extracted from eucalyptus leaves that have been dried, crushed, and distilled. The oil must be diluted after extraction before it may be used medicinally. Eucalyptus oil is frequently used to treat many health issues, including coughing.

What are the uses of eucalyptus oil?

To relieve coughs

Eucalyptus oil has long been used to treat coughs. In fact, eucalyptus oil is now one of the active constituents in specific over-the-counter cough treatments.

A 2012 research on children discovered that applying an ointment containing the oil of the Australian tree helps ease coughs and nasal congestion at night, allowing them to sleep better.

Not only does eucalyptus oil ease coughs, but it may also assist clear mucus or phlegm from the chest. Try eucalyptus oil if you cough but can’t get the phlegm out of your chest.

In a container, combine a cup of hot water and 12 drops of eucalyptus oil, then inhale the steam thrice daily. This approach can thin the mucus, making it simpler to expel when coughing. 

Applying Eucalyptus oil-containing topical medicine to the chest has the same effect.

Not only can eucalyptus oil aid with coughing, but it can also help with other respiratory issues, including bronchitis, flu, sinusitis, and asthma. This is due to the presence of cineole (cineole and eucalyptol), which is responsible for the strong scent and has therapeutic effects.

According to a 2010 analysis, eucalyptus oil has high antibacterial, antiviral, and antifungal effects, which might explain why it is used as traditional therapy for respiratory disorders.

Eucalyptus oil can help with the following respiratory issues:


Eucalyptus tea or oil has long been utilized in traditional herbal therapy, either by drinking or applying it to the chest. The German Commission E, a team of specialists assessing herbal medicine, has authorized both approaches for treating bronchitis. 

It is a common inflammation in the tube lining that transports air to and from the lungs that are frequently caused by the flu.

According to 2013 research, persons suffering from bronchitis can benefit from oral cineole therapy.

Two hundred forty-two individuals were given either 200 mg of cineole three times each day or a placebo for ten days. 

After four days of therapy, the cineole-treated group improved more significantly in acute bronchitis symptoms, particularly the number of coughing bouts.


Although further study is needed to validate its advantages, eucalyptus oil is commonly used via inhalation to help ease cold symptoms.

When breathed, the vapor of the essential oil that enters the respiratory system is thought to prevent muscular spasms that can restrict the airway and make breathing difficult.


The cineole in Eucalyptus can also aid in the treatment of acute sinusitis, which frequently begins as a cold and escalates to a bacterial infection.

Double-blind research conducted in 2004 looked at 150 persons with acute sinusitis who did not require antibiotic therapy. 

The researchers discovered that those who took 200 milligrams of cineole orally three times a day healed quicker than those who received a placebo.


Early study shows that the eucalyptol in eucalyptus oil can help persons with asthma break down phlegm. At the same time, some persons with severe asthma can reduce their steroid prescription dose and replace it with eucalyptol. 

However, it would be best if you did not try this treatment without the guidance and supervision of a doctor.

Is the eucalyptus tree flammable?

When it’s hot, the trees soon burn like torches, slathering our neighborhood with fires. Eucalyptus, often known as the gum tree in Australia, may survive in fire-prone environments. 

The fallen eucalyptus leaves make a dense, combustible carpet on the ground. The dried bark generally peels off, falls to the ground, and fuels the fire.

The eucalyptus tree’s oil has a distinctive pungent scent and is combustible. The mix of oil, leaf litter, and dry, peeling bark may quickly convert a tiny fire into a raging flame. 

In New South Wales, eucalyptus trees are widely cultivated, particularly the blue gums variety (Eucalyptus globulus), sometimes known as the “gasoline tree.”

Eucalyptus trees cope better than other plants after a fire. Eucalyptus seeds are capsules that open when burnt and develop quickly in the fertile soil that remains after the fire.

Allow one area to burn extensively, and the Eucalyptus will take over after the fire. The tree can outperform other plants by growing quickly in a few years.

Eucalyptus is classified as an invasive species. Because of its quick expansion and capacity to supplant native plants and repel local wildlife, Eucalyptus is considered a major hazard by the California Invasive Plants Control Agency (Cal-IPC)

Fighting flames is still tough since Eucalyptus has spread over the planet.

How to handle eucalyptus oil safely?

Avoid breathing vapors, mists, aerosols, and skin and eye contact. Keep out from the reach of children. Combustible vapor mixes may be formed with air. 

Vapor may travel a considerable distance to the ignition source and then flashback to its inception. 

There must be no open flames, furnaces, pilot lights, spark-producing switches, or electrical equipment anywhere in the work area since these are all potential ignition sources. 

Do not smoke when handling eucalyptus oil. Avoid static discharges by taking the necessary measures.
