The uses and benefits of tea tree oil have expanded as more has become known about the plant and its oil, which is why it is so commonly listed as an ingredient in shampoos, skin creams, shampoos, disinfectants, detergents and much more.

Whilst research continues into the medicinal effectiveness of tea tree essential oil, countless studies have already published positive results that indicate it could provide a sustainable alternative to some traditional treatments.

With that in mind, we’ve put together 10 tea tree oil benefits and uses to give you a better understanding of its history, how it works, how to use it and how it can work as a natural remedy.

What is tea tree oil?

Tea tree oil is an essential oil produced through the steam distillation of leaves taken from the Melaleuca alternifolia plant. It has a camphor-like fragrance (spicy, cooling, herbal and woody) and its appearance can range from being completely colourless to pale yellow.

People use it to treat a wide range of minor ailments, relying on its natural properties to improve various skin conditions, ward off insects and to sanitise household surfaces.

As we explain below, there are lots of different ways you can use tea tree oil to potentially benefit your body, all of which are backed by scientific research.

How does tea tree oil work?

Tea tree oil has a high amount of terpene, which is ideal for combatting fungus and bacteria and also reducing allergic skin reactions.

Because the oil is extracted from the Melaleuca plant using a steam distillation process, it is able to retain the sesquiterpenes, monoterpenes and terpene hydrocarbon compounds that can provide antiviral, antifungal and antibacterial protection.

These hydrocarbons help the scent of the oil to travel and enter skin pores to deliver aromatic treatment benefits. Many people use the oil topically (when diluted with a carrier oil), although the benefits of tea tree oil can also be effective when diffused or mixed into a warm water bath.
