What Is Eucalyptus Oil?

Eucalyptus oil is extracted from the leaves of a variety of eucalyptus trees. The trees are members of the Myrtaceae plant family, found in Australia, Tasmania, and adjacent islands. There are around 500 species of eucalyptus, but the essential oils of Eucalyptus salicifolia and Eucalyptus globulus (commonly known as fever tree or gum tree) are harvested for therapeutic purposes.

The bark of the eucalyptus tree is used for papermaking, while the wood is utilized as fuel and lumber in Australia and extracting essential oils.

Eucalyptus oil has traditionally been used as an analgesic to treat pain and was prized for its ability to reduce inflammation and improve respiratory ailments. Today, the advantages and applications of eucalyptus oil are many, and the oil is widely utilized in therapeutic ointments, fragrances, vapor rubs, and cleaning goods.

Eucalyptol, also known as 1,8-cineole, is an antioxidant, anti-inflammatory, and pain reliever that makes up 70–90 percent of the content of eucalyptus oil. Eucalyptus is also renowned for its capacity to combat bacterial, viral, and fungal diseases and clear mucus from the respiratory system. Eucalyptus is one of the most helpful and adaptable essential oils to have in your medicine cabinet for these reasons.

Remember that cold extraction, which typically employs CO2, is the greatest approach for preserving the range of beneficial chemicals found in essential oils. Conversely, steam distillation and other processes that use a lot of heat or volatile chemicals won’t produce as many useful molecules.


1. Enhances Respiratory Health

Eucalyptus essential oil is thought to be one of the most beneficial essential oils for various respiratory problems, including chronic obstructive pulmonary disease (COPD), asthma, bronchitis, sinusitis, the common cold, cough, and flu.

Eucalyptus essential oil may aid with various respiratory issues by stimulating the immune system, providing antioxidant protection, and improving respiratory circulation. Because it triggers your nose’s cold receptors, eucalyptus makes it easier to breathe when you’re feeling stuffy and your nose is running, and it also acts as a natural sore throat treatment. Plus, when you’re feeling clogged and hard to breathe, eucalyptus might help you sleep.

In animal experiments, Eucalyptus globulus, which contains the active component cineole, has been shown to help lessen the inflammatory effects of chronic bronchitis and block the hypersecretion of airway mucins.

Aromatic herbs were used to treat upper respiratory tract infections in randomized research published in Evidence-Based Complementary and Alternative Medicine. Participants were treated with an essential oil combination that contained eucalyptus, peppermint, oregano, and rosemary essential oils in six primary care clinics in northern Israel. The experimental group sprayed the essential oil combination five times per day for three days and compared the effects to those of a placebo spray.

Researchers discovered that individuals in the essential oil group reported a higher reduction in symptom intensity 20 minutes after applying the spray than those in the placebo group. Sore throat, hoarseness, and cough were among the symptoms assessed.

2. Cough Relief

Eucalyptus oil is one of the most beneficial essential oils for cough because it acts as an expectorant, clearing your body of the bacteria and toxins that cause you to cough and feel ill. Eucalyptus oil makes breathing easier when you feel stuffy, and your nose runs.

The effectiveness of cineole, one of the primary components of eucalyptus oil, on patients with acute bronchitis was studied in placebo-controlled double-blind research done in 2014. When patients were given 200 mg of cineole three times a day for ten days, their bronchitis symptoms improved significantly compared to those who were given a placebo. In addition, after four days of therapy, those who received cineole had considerably fewer cough episodes.

3. Relieves Allergies During the Seasons

Eucalyptus oil has anti-inflammatory and immunomodulatory components, such as eucalyptol and citronellal, which is why it is often used to treat seasonal allergy symptoms.

Eucalyptus oil not only has antiseptic, antibacterial, and anti-inflammatory qualities, but it may also have immunoregulatory effects, according to animal research published in BMC Immunology. When the body comes into touch with an allergen, this may change the immunological response.

4. Defends Against Infections

Several studies have shown that eucalyptus oil and its primary component, eucalyptol, have antibacterial properties against a wide range of bacteria, viruses, and fungi.

Eucalyptus may be used aromatically or topically to combat the bacteria that make you ill. This is why one of eucalyptus oil’s advantages is its potential to strengthen your immune system. For example, eucalyptus oil was discovered to have inhibitory effects against Escherichia coli and Staphylococcus aureus (which may cause staph infection) in lab research published in the Asian Pacific Journal of Tropical Biomedicine.

Another lab research found that eucalyptus oil had a direct antiviral impact against the herpes simplex virus, which may cause genital herpes and other illnesses.

Eucalyptus essential oil may also be used to treat fungal illnesses such as candida and toenail fungus.

5. Reduces Inflammation and Pain

The capacity of eucalyptus oil to ease pain and reduce inflammation is a well-known advantage. In addition, eucalyptus may assist in relieving muscular discomfort, soreness, and swelling when applied directly to the skin.

The benefits of breathing eucalyptus oil on pain and inflammatory reactions following total knee replacement surgery were studied in a randomized clinical study published in Evidence-Based Complementary and Alternative Medicine. Three days in a row, patients breathed either eucalyptus or almond oil for 30 minutes during therapy. After that, pain, blood pressure, and heart rate were recorded. The eucalyptus group had considerably reduced pain ratings on all three days and systolic and diastolic blood pressure values on the second day. This implies that inhaling eucalyptus oil may be used as a “nursing intervention for pain alleviation.”

6. Helps with Headaches

One of the finest essential oils for headaches is eucalyptus oil, which may help relieve sinus pressure and create a lot of discomfort and stress. It also contains energizing effects that may improve mental clarity and induce face muscle relaxation, which is beneficial when you have a headache caused by stress or weariness. When eucalyptus oil is mixed with peppermint oil and a carrier, the effects seem to be the most prominent.

Eucalyptus oil possesses anti-inflammatory and analgesic properties, according to randomized research published in 2011. In addition, it may assist persons with respiratory disorders in alleviating headache tension produced by sinus pressure by inhibiting the development of mucus in the airways and improving breathing.

7. Wound Care for Aids Patients

I’m often asked whether eucalyptus oil is beneficial to the skin. Eucalyptus is an excellent treatment for skin irritations such as wounds, cuts, burns, blisters, and even bug bites due to its antibacterial and antiseptic characteristics.

According to the following, Eucalyptus oil is effective against blisters, boils, cuts, cold sores, insect bites, shingles, sores, ulcers, wounds, abscesses, athlete’s foot, and bacterial dermatitis a 2017 review that evaluated the use of essential oils as an alternative medicine for dermatological conditions. In addition, it possesses antibacterial, antiviral, and antifungal effects, making it an effective treatment for various skin problems. This is why eucalyptus oil has been used as a medicinal treatment for centuries.

8. Helps with Earaches

Eucalyptus oil may be used to relieve ear infection symptoms and earaches because it is an expectorant that helps unclog your respiratory system and has antibacterial characteristics that assist in removing an infection that may cause fluid to build up in your ear canal.

Earaches or discomfort caused by the typical cold or cough, nasal congestion, a bacterial infection, seasonal allergies, or any other illness that causes the accumulation of fluids in your ear canals may be relieved with eucalyptus oil.

9. Improves mental acuity 

Eucalyptus oil enhances energy and mental clarity because of its energizing, calming, and cleansing characteristics. In addition, it may aid in clearing your airways, allowing more oxygen to enter your lungs, and alleviating brain fog.

A 32-person, double-blind, placebo-controlled, randomized cross-over trial indicated that when a mixture of eucalyptus oil, peppermint oil, and ethanol was applied to broad portions of the forehead and temples, the participants’ cognitive function improved. Muscle relaxation and mental relaxation were other benefits of the essential oil mix.

10. Keeps Rats Away

Did you know that eucalyptus oil may naturally help you get rid of rats? A 2014 research published in The Scientific World Journal reveals that eucalyptus oil may be used to defend an area against house rats, which may seem like an unexpected eucalyptus oil benefit.

The rats stopped eating in the area where the oil was sprayed in laboratory cages. Researchers found that food intake was much lower on the treatment side compared to the untreated side, indicating that eucalyptus essential oil had a considerable repelling impact.

Before applying eucalyptus oil to the skin, dilute it with a carrier oil (such as coconut oil) if you have sensitive skin. I also recommend diluting eucalyptus before applying it to your children’s skin and avoiding putting it on their faces since it may be unpleasant.

Eucalyptus oil toxicity has been reported in newborns and young children. Therefore, minors should not consume eucalyptus oil. If you’re going to use eucalyptus oil on kids, diffuse it at home or dilute it with a carrier oil before applying it topically.
