This inexpensive and safe to use as directed oil is also backed by science highlighting its many benefits. In this article, we will go over the many everyday uses for tea tree oil as well as give you the proper guidance to use the oil effectively and safely.

What Is Tea Tree Oil?

Australia is home to the Melaleuca Alternifolia tree, the source of Tea tree oil. These trees native to New South Wales, and Queensland Australia have provided Aborigines with Tea tree oil for centuries. The Aborigines crush the leaves from the tree to extract the oil, using it for their traditional medicine. By inhaling the oil the Australian natives would treat colds and coughs or apply it directly to their skin for healing ailments. 

100% undiluted or “neat” Tea tree oil is widely available. Products designed for the skin are available in diluted forms ranging from 5-50% in strength. Tea tree oil has many compounds such as terpinen 4-ol, that have been tested to kill certain viruses, bacteria, and fungi. Terpinen 4-ol has been found to increase the activity of white blood cells, helping to fight germs and foreign invaders in the body. These valuable properties make tea tree oil a natural remedy for treating fungal and bacterial skin conditions, promoting healing, and preventing infection. 

Natural Hand Sanitizer

Tea tree oil has been tested to prove it makes an ideal hand sanitizer that is natural and effective. Killing bacteria and viruses that are responsible for E.coli, S. pneumoniae, and H. influenzae, make this a great choice for natural hand sanitizer. 

Other studies have been done testing several types of cleansers with tea tree oil added, boosting their effectiveness to fight E. coli and other viruses. You can easily make your own tea tree oil hand sanitizer from home.  Natural Insect Repellent

Studies have shown that tea tree oil may help keep pesky bugs away. In these studies, they found that 24 hours after being treated with tea tree oil, cows had 61% fewer flies than cows not treated with the oil. These studies have proven that tea tree oil has a greater ability to repel mosquitoes than DEET, the most common ingredient in commercial repellents. 

Natural Deodorant

With tea tree oils antibacterial properties it may be an effective use to help control underarm odor. Sweat itself does not have a smell, however, when the sweat combines with the bacteria on your skin, an odor is produced. 

The underarm area is home to a large concentration of sweat glands, and mainly responsible for what we refer to as “body odor”. The antibacterial properties in tea tree oil are what make it an ideal natural deodorant. 

Local Antiseptic 

Tea tree oil can be used to disinfect and treat minor cuts and scrapes, killing S. aureus and other bacteria that may cause infection in open wounds. Injuries that cause broken skin make it an easy entrance for germs to get in the bloodstream, which may lead to infection. 

To disinfect a cut or scrape, follow these steps:

  • Clean the cut thoroughly with plain soap and water
  • Mix one drop of tea tree oil with one teaspoon of coconut oil 
  • Apply a small amount of the mixture to the injury and cover with a bandage
  • Repeat this process once or twice daily until a scab has formed

Wound Healing

Along with preventing infection, tea tree oil can also be used to speed up the healing of wounds. Studies have shown that tea tree oil may help reduce inflammation and encourages the activity of white blood cells that are essential to the healing process. 

In another small study using 10 people with wounds, by adding tea tree oil to their normal wound treatments, the healing time in all but one of the participants was decreased. You can add a few drops of tea tree oil to the new wound dressing every time it is applied.

Acne Defence 

Studies have shown that tea tree oil is a powerful fighting agent against acne. It reduces the amount and overall intensity of acne, in one study using 5% tea tree gel was three times as effective at reducing the number of lesions than a placebo. Found in another study it reduced the severity of acne by six times that of the placebo, showing that tea tree oil is as effective as benzoyl peroxide, the most common anti-acne medication.

Nail Fungus Defense 

Nail fungus is quite common, it can be unsightly but is not dangerous. Medications are available to help treat nail fungus but a more natural approach may be preferred. Using tea tree oil alone or mixed with other natural remedies has been shown to be an effective way to get rid of nail fungus. 

In a study, people with nail fungus used tea tree oil undiluted or an antifungal medication for six months. By the end of the six months, 60% of people in each group had partial or full healing of the fungus. To use it as an antifungal you can use a few drops alone or mix it with an equal amount of coconut oil and apply it to the affected areas. Wash your hands afterward to prevent spreading the fungus. 

Natural Mouthwash

Tea tree oil has research suggesting that it may fight germs that cause tooth decay and bad breath. One study showed that tea tree oil was more effective against plaque-causing bacteria than chlorhexidine, a common disinfectant, and oral rinse. The taste was also found to be more tolerable.

A controlled study of 158 people compared the effects of athlete’s foot medication with tea tree oil. 72% of the tea tree oil users had significant improvement, whereas the placebo group only had 39% improvement. However, the studies also show that even though tea tree oil helps to reduce the symptoms of athlete’s foot, it was not as effective at getting rid of the fungus.

To treat athlete’s foot naturally here is a treatment:

  1. Combine 1/4 cup arrowroot powder, 1/4 cup baking soda and 20–25 drops of tea tree oil

There is one case where an 18-month-old boy suffered from serious injuries after accidentally ingesting the oil. Therefore you should keep the oil out of reach of children. 

Test a drop or two on a small area of your skin and wait 24 hours to see if there is a reaction, before using the oil for the first time. This is important because some people develop contact dermatitis from the oil, one of the conditions that tea tree oil can help treat. 

People with sensitive skin may also experience skin irritation using undiluted tea tree oil. If you have sensitive skin, try diluting the oil with olive oil, coconut oil, or almond oil it is best to mix it with equal or greater parts.
