As an immunostimulant, eucalyptus oil boosts immunity and provides antioxidant protection to improve respiratory circulation. Even more, eucalyptus activates the nose’s cold receptors making it easier to breathe when feeling congested (3,4

An animal study also showed that eucalyptus could reduce chronic bronchitis’s inflammatory effect and inhibit airway mucins’ hypersecretion.

More research published in Evidence-Based Complementary and Alternative Medicine looked at treating upper respiratory tract infections with aromatic use essential oils. The study treated participants with a blend of eucalyptus, peppermint, oregano, and rosemary essential oils. The study compared the placebo group results and the experimental group who applies the oil as a spray five times a day for three days.

Research shows that eucalyptus oil’s antimicrobial properties can stand up against various strains of bacteria, fungi, and viruses. 

study showed that eucalyptus oil has an antiviral effect on the herpes simplex virus. 

Additionally, the Asian Pacific Journal of Tropical Biomedicine published a study that showed eucalyptus oil’s inhibitory effects against Escherichia coli and Staphylococcus aureus, which cause staph infections. 

Furthermore, eucalyptus has potent antifungal properties that can combat common fungal infections like candida and toenail fungus (6).  

Wound Care 

Eucalyptus oil’s antimicrobial, antiviral, antifungal, and antiseptic properties make it a great natural remedy for wounds, cuts, sores, burns, and insect bites. 

A 2017 review looked at the effects of eucalyptus essential oil on dermatological conditions and found it effective against cold sores, insect bites, sores, ulcers, wounds, blisters, boils, and athlete’s foot, and bacterial dermatitis! 

Combine 1-2 drops of eucalyptus with a skin-loving carrier oil like coconut oil and apply to the area of concern. 

Alleviates Earaches 

As an expectorant, eucalyptus oil clears the respiratory tract of mucus and, in many cases, can unclog fluid build up in the ear canal. To use eucalyptus to improve ear infection symptoms due to nasal congestion, bacterial infections, allergies, or the common cold, diffuse five drops! 

Reduce Pain and Inflammation 

Topical use of eucalyptus oil can aid in pain relief for muscle soreness due to its analgesic and anti-inflammatory properties and its cooling effects. Dilute 1-2 drops of eucalyptus with a carrier oil and apply to the area of discomfort. 

In addition to topical pain relief, a study published in Evidence-Based Complementary and Alternative Medicine evaluated the effects of aromatic use of eucalyptus oil. The trial looked at the pain and inflammatory responses of patients after total knee replacement surgery. During rehabilitation for three consecutive days, patients either inhaled eucalyptus oil or almond oil for thirty minutes. Researchers looked at pain, blood pressure, and heart rate and found that the eucalyptus group showed significantly lower blood pressure groups on the second day. More research needs to be done to study the inhalation effects of eucalyptus on pain relief, but this study is promising.
