According to researchers, this is one of the chief ways aromatherapy has a direct effect on the immune system. For instance, essential oils stimulate the hypothalamus. The hypothalamus is where hormones are produced and are one of the most important parts of the limbic system.

Cytokines are also responsible for building new blood cells and how, for example, cancer cells migrate which promotes further growth. If they were not present, it could lead to immune diseases such as asthma and arthritis.
In a study undertaken in January 2019, titled “Essential oils and its bioactive compounds modulating cytokines” on how essential oils may help with asthma, it was concluded that essential oils’ main benefit was the regulation of cytokines.

Essential oils increase phagocytosis
Using essential oils can increase phagocytosis by white blood cells to fight off invaders.
Phagocytosis is a process where large particles are engulfed by a cell so they can be destroyed and eliminated from the body.
In simple terms, essential oils send signals through transporters which prompt damaged cells to repair.
Essential oil transporters
Cells also get the added benefit of receiving essential oils through essential oil transporters that help oils get into the cells quickly and efficiently.
Essential oils are transmitted into the cells where they act as a messenger, warning the cells of impending danger or damage.
Chemical messages
They then send essential oils-specific information so the oils know what type of help is needed. They respond by sending chemical messages with essential oil-specific instructions on how they need to be repaired. This helps the cells to continue functioning in areas where the oils are present.
This happens even if there is significant damage to the cells.These chemical messages also tell essential oils what the body is lacking so they can provide assistance. Essential oils act like this for all cells in the body, including lymphocytes and other essential immune systems.

The blood-brain barrier
According to scientific studies, essential oils can also assist with crossing the blood-brain barrier. This means they can pass essential nutrients to the brain and help essential cells function better.
Essential oils provide a nutrient delivery system
The essential oils provide an efficient delivery system for essential nutrients.
As essential oils are directed around the body by essential receptors they can deliver essential acids directly to where they’re needed.
In this way, essential oils work symbiotically with the immune system to boost health and kickstart immunity.
