The best essential oils for boosting the immune system
These oils can support our natural defence system and keep us healthy.

Essential oils can provide a helpful boost to our immune response.
Whether you use them in cleaning sprays, massage blends, or simply in your diffuser, the right essential oils can strengthen our body’s natural defences and offer an extra layer of protection to our health. We’ve collected some of our top picks for immune-boosting essential oils that you can use to guard your wellness.

Bergamot oil
Research has suggested that bergamot oil encourages the production of white blood cells in the body. White blood cells are a key part of the immune system and play an important role in neutralising infections, so bergamot’s ability to boost our white blood cell count can speed up recovery overall. As well as stimulating the immune system, bergamot can protect it against factors which may weaken it. A highly relaxing, de-stressing oil, it can prevent the lowered immune activity that serious stress can cause. Bergamot also has strong cleaning properties, allowing it to prevent harmful microorganisms infecting us in the first place and reducing the strain on the immune system.

Eucalyptus oil
Immune cells ‘ingest’ cells via a process called phagocytosis. Eucalyptus can enhance phagocytosis, allowing immune cells to work faster at eradicating infections and speeding up recovery times. Eucalyptus is also an anti-inflammatory oil, reducing inflammatory cytokines and relieving the swelling often cause by the initial response of the immune system.

Lemon oil
Lemon oil’s powerful antioxidant abilities are highly beneficial to the immune system, helping to reduce the destructive work of free radicals. Lemon oil can also encourage the production of white blood cells, an effect which is though to be due to the presence of the component d-limonene. It has even been suggested that lemon oil plays a role in protecting the health of the liver, which is an important part of the immune system.
Tea tree oil
Tea tree oil has strong cleaning properties and can aid the immune system in the task of guarding our health by reducing our exposure to harmful microorganisms. The oil can also reduce inflammation caused by cytokines, lessening strain on the body.
You can put a few drops of immune-boosting essential oil into a diffuser.
Lavender oil
The powerful stress-relieving properties of lavender oil can help to ensure that severe stress does not have an immunosuppressant response on our defence system, and remove obstacles to our quick recovery. Lavender oil has also been found to enhance phagocytosis and reduce bacterial growth, and exposure to this floral oil has even caused increased levels of IgA in saliva – a marker of immune response.
Clove bud oil
Research has found that clove oil can boost the immune response of antibodies and proteins, speeding up the process by which hostile entities are discovered and neutralised. An anti-inflammatory and antimicrobial oil, clove also has the ability to reduce inflammation in the body and protect us from infections.
Frankincense oil
Frankincense essential oil demonstrates strong immuno-stimulant activity, encouraging an increased immune response. The oil facilitates a quick recovery from all kinds of conditions and has been investigated for its role in combatting gingivitis.

Niaouli oil
Niaouli oil is said to stimulate blood circulation, metabolic processes, and the secretion of hormones and enzymes, all of which are though to support an effective immune response. The oil also promotes cellular immunity by encouraging T-cells to attack infected cells.
Many of these oils may do their best immuno-stimulant work when paired with other immune-boosting scents. Not sure where to start? Try an expertly-formulated combination of bergamot, eucalyptus, lemon and tea tree in our Immune Boost Pure Essential Oil Blend.
