The immune system is our body’s defense against a wide variety of pathogens, viruses, and diseases. A properly functioning immune system helps our bodies fight off disease and keeps us happy and healthy. Getting quality sleep, maintaining a healthy diet, exercising regularly, and reducing our toxin load have a big impact on our immunity. However, another way we can support the immune system is by adding essential oils to our daily regimen. Scientific studies demonstrate that the diffusion of essential oils can purify and cleanse the air, providing added protection.

What are essential oils?

Essential oils are pure essences extracted from different parts of fruits, trees, flowers and stems. Pure essential oils are those that have no additives at all — no fillers, extenders, synthetic materials. Small amounts of immune boosting essential oils can go a long way in helping get rid of bacteria and viruses in our bodies and in our environment.

How to use them?

The most common way to use essential oils is to inhale them, either directly out of the bottle or by using a diffuser or humidifier. You can also dilute essential oils with a carrier oil and apply it directly your skin. Or you can get creative and add the mixture to a body wash, shampoo, or bath.

Tea tree, also known as melaleuca, is highly regarded for its outstanding anti-microbial properties and its ability to stimulate the immune system, which helps fight off infection and disease. Tea tree is also one of the more gentle essential oils that you can use, making it easy to incorporate into your daily routine.


Lavender is one of the most widely used essential oils across the world. Lavender has anti-viral, anti-microbial, and anti-bacterial properties that make it a great addition to our body’s natural defense system.

Along with relieving stress, lavender is filled with antioxidants that remove free radicals from our system which are often associated with cell damage, illness, and aging.


Lemon is a great oil to use for detoxification of the body because of the abundance of vitamins and minerals it contains.
