Tea tree oil benefits

If you thought tea tree oil was just another passing natural health fad, think again.

Sourced from the leaves of the Melaleuca alternifolia plant, indigenous to Australia, tea tree oil has long been used in traditional medicine. More recently, scientific studies have unearthed a slew of health benefits directly linked to the strong antibacterial and anti-inflammatory properties of terpinen-4-ol, the powerhouse behind the oil’s efficacy.

In fact, when it comes to treating conditions such as athlete’s foot, acne, and fungal infections, tea tree oil has been proven to be as effective as popular synthetic over-the-counter treatments. When used correctly, tea tree oil offers a safe and natural alternative to chemical-laden treatments.

However, the most appealing aspect of this essential oil lies in its sheer versatility. A single bottle of tea tree oil will readily serve an entire household. Whether you need to soothe skin irritation, disinfect wounds, ease respiratory issues, fight bad breath, remove mold, freshen laundry, or repel pests, you can count on tea tree oil to be up to the job.

Tea tree oil uses

Often referred to as a “miracle oil” and a “medicine cabinet in a bottle,” tea tree oil has a long list of scientifically backed benefits. Let’s delve a little deeper to find out more about some of its incredible uses.

Remarkably, the below list of tea tree oil uses only scratches the surface, and it’s easy to see why so many consider it the ultimate cure-all essential oil.


If you’re looking for a natural solution for acne, tea tree oil is a great option. Studies suggest that a 5% tea tree oil solution is as effective as a 5% dose of benzoyl peroxide, the active ingredient found in leading chemical-based acne treatments.

Tea tree oil: what to look for

Once you know the basics, selecting a top-notch tea tree oil is a breeze. Here's what to look for while you shop.


Purity is important. Some tea tree oils are pre-diluted with other essential oils such as eucalyptus or peppermint. While these oils may smell great, dilution unfortunately makes for a less-powerful product. For the best results, look for 100% pure tea tree/melaleuca oil.


Even if you have no interest in jumping on the organic lifestyle bandwagon, we strongly recommend that you consider an organic tea tree oil. This is for the simple reason that most organic tea tree oils are known to boast higher levels of purity and increased concentrations of bacteria-fighting terpinen-4-ol.

"Tea tree oil is in no way related to Camellia sinensis, the plant used to make black, green, and oolong teas."

Terpinen-4-ol concentration

While a number of compounds work together to make tea tree oil the natural wonder that it is, terpinen-4-ol is the undisputed star of the show. Much of the oil’s impressive antibacterial properties stem from terpinen-4-ol, and higher concentrations of this compound translate to improved overall efficacy.

Concentrations typically start out at around 10% and are capped at 45%, as this is the highest naturally occurring percentage of terpinen-4-ol. Brands claiming concentrations higher than 45% have most likely been chemically modified.

Bottle color

The manner in which tea tree oil is packaged can have an impact on its potency. In addition to air and heat, light has been shown affect the stability of essential oils, speeding up oxidation and in some cases rendering it completely useless. Furthermore, light exposure has been shown to increase levels of para-cymene, a known skin irritant.

For the best results, choose a dark brown glass bottle, and store your tea tree oil in cool, dark, and dry conditions.

A four-ounce bottle typically costs anywhere between $10 and $30. While many excellent tea tree oils are priced somewhere in between, budget options are more likely to be mixed with other oils and, in some cases, even chemicals.

Regardless of the price, it's best to inspect the label before you buy.

Expert Tip
It may be tempting to buy tea tree oil in bulk, but keep in mind that it has a shelf life of approximately six months.


There are hundreds of great tea tree oil recipes and concoctions to try out, but that doesn't mean you have to purchase a long list of ingredients before you open the bottle. These simple tea tree oil tips can be used immediately.

  • Use tea tree oil to clear the air. Coughs and sneezes can often leave a lot of nasties floating around. Using tea tree oil in a diffuser or diluted with water in a spray bottle will help eliminate airborne bacteria.

  • Use tea tree oil to rejuvenate your skin. Sprinkle a drop or two of tea tree oil into your bath water to revitalize your skin and fight off infections.

  • Give your toothpaste an antibacterial boost with tea tree oil. Adding just a drop to your toothpaste each time you brush can improve oral hygiene and promote the healing of mouth ulcers.

  • Create an effortless antibacterial hand and body soap using tea tree oil. You can make your own chemical-free sanitizing soap by adding a few drops of tea tree oil to liquid Castile soap.

Q. What's the best way to use tea tree oil for acne?

A. Everyone's skin is unique, and when trying out any new remedy for the first time, it's safest to test a small amount on a localized area first. With that in mind, here are two easy ways to use tea tree oil as an acne treatment.

  1. Spot treatments: Dip a Q-tip into one or two drops of undiluted tea tree oil. Gently dab onto pimples and bumps, taking care not to rub or spread it over larger areas. Repeat two to three times per day. Alternatively, you could dilute the oil with water before dabbing it onto skin.

  2. Cleanser: Dilute one part tea tree oil in nine parts water and mix well. Use a cotton ball to apply the solution to affected areas. Leave on for 15 to 20 minutes before rinsing. Repeat twice a day.

Q. I heard that tea tree oil can be used to treat head lice. Is this true?

A. While tea tree oil is not a cure for lice, it can be used as a deterrent if there has been an outbreak near you. To use tea tree oil as a preventative measure, you can apply a few drops (no more than that) directly to the scalp. Alternatively, you can mix about 10 drops of tea tree oil with another oil, such as olive oil, and allow it to sit for several hours on the hair before washing it away.

Notably, tea tree oil should not be applied to the skin of babies, young children, and pregnant women. If you or someone in your household is battling lice, we encourage you to speak with your physician before using tea tree oil as a preventative measure.
