Best Immune Stimulant Essential Oil

Tea tree is one of my favourite immune essential oils, and, I think, generally overlooked for it’s germ fighting properties. The plant is native to Australia and the essential oil is steam distilled from leaves. It is widely used in cosmetics for its combative effect on the skin, but let’s learn why it’s one of the best for stimulating the immune system.



About Tea Tree

One of the main constituents in tea tree is called terpinen-4-ol, which is a monoterpenol (monoterpene alcohol). Studies show that terpinen-4-ol increases the activity of white blood cells. White blood cells are the part of the immune system that fight off germs.

White blood cells are produced in the bone marrow, as well as lymph nodes and the spleen, in response to the presence of abnormal organisms/invader organisms within the body. These white blood cells flow through your bloodstream to battle bugs and germs and foreign invaders that threaten the body. When a particular area of the body is under attack, the white blood cells rush in and attack the invader to help destroy it.

One of my favourite places to apply tea tree in consideration of this is over the spleen.

Dilute with carrier oil and apply over your spleen area front and back, located on your left side under up under your ribs.


One of the things to remember is that tea tree is widely available on the market. You can find tea tree essential oil at your local Walmart, drug store, and I’ve even seen it at cheap craft stores and dollar stores. These essential oils are extremely poor quality essential oils and should never be used for health purposes, or to treat the bodies.

As an aromatherapist in training, I am extremely picky about the essential oils I use. I’ve been using essential oil for close to 15 years and I choose only to use this brand because I’ve personally seen the farms, the distilleries, research labs, and warehouses.
