Tea Tree Essential Oil kills bacteria, viruses, and fungi on surfaces and in the air1 making this oil a great cleaner.

Eases Congestion

While you’re killing microbes in the air, this oil will also help break down mucus due to sinus tissue inflammation2. When you’re feeling stuffed up, this oil will help soothe your congestion. 

Fights Acne

Tea Tree oil for acne scars? Heck yes! Acne happens when bacteria get clogged into our pores. Our skin reacts by creating inflamed bumps also known as pimples. Since Tea Tree is really good at killing germs and is also anti-inflammatory, it can be used to prevent and fight acne3.

This oil is so good for the skin that it’s included in our “Best Essential Oils for Clear Skin.”

Kills Microbes in the Air

Tea Tree Essential Oil promotes respiratory health by killing microbes in the air4. It also wards off molds and mildew that can cause breathing problems. One of the best ways to get these benefits is by diffusion.

Prevents Lice

Tea Tree oil for hair lice? Yep! The main naturally occurring chemical in Tea Tree Essential Oil is known to kill lice5. So if you are concerned about the spread of lice in your workplace or children’s school, you can add a few drops of Tea Tree Oil to your shampoo to help prevent lice from making a home in your hair.

For the best results, use our all-natural shampoo base! It’s safe to use and very effective in cleaning your hair.

Relieves Pain

As mentioned above, Tea Tree Essential Oil is good at fighting inflammation6. Inflammation happens when our bodies rush to heal or protect an area of our body. In some situations like joint discomfort, our body is creating inflammation even though there is nothing for the body to fight. Tea Tree helps soothe and break up inflammation to help soothe the discomfort.

We know how essential oils work and what their benefits are by looking at their natural chemical makeup. Tea Tree Essential Oil is made up of several different chemicals created by the plant, but it’s mostly made up of terpinene-4-ol (42.27%).

Terpinene-4-ol is a naturally occurring chemical known to kill germs, fungi, and viruses, support the work of white blood cells (fight inflammation), block the sensation of pain, and stimulate the immune system. It’s also known to kill lice.
