Usage/Utilisation : Tea tree oil is one of the best essential oils for antimicrobial uses. It fights a wide range of bacteria, yeasts, and fungi, helping to get rid of infections and treat a range of conditions caused by bacterial or fungal overgrowth.


Treat athlete’s foot. Athlete’s foot is caused by a fungal infection, and tea tree oil’s antifungal activity is particularly effective against it. In one study, a 25 percent tea tree oil cream was far more effective than placebo at reducing infection and getting rid of symptoms.[1] Try a footbath with a few drops of the oil in a bucket of warm water.

Clear up acne. Tea tree oil is commonly found in many natural products aimed at treating acne, as it helps to fight bacteria associated with acne and helps reduce inflammation. Products with 5 percent tea tree oil can help to reduce the number of acne lesions by 24% to 62% when applied twice daily for one to two months.[2]

Get rid of lice. Lice can be especially hard to get rid of, particularly with natural products. But laboratory studies show that tea tree oil can kill lice in only thirty minutes, suggesting that it may be an effective natural alternative to conventional lice treatment.[3] Try mixing a few drops of tea tree oil with a few drops of lavender oil and adding it to a small amount of mild shampoo. Lather into the scalp, leave on for thirty minutes, rinse, and repeat as necessary. Be sure to follow other lice treatment strategies, including using a lice comb and thoroughly cleaning your home and clothing.

Fight bad breath. Bad breath is caused by bacterial overgrowth in the mouth. Tea tree oil has antimicrobial activity against many of the bacteria responsible for bad breath symptoms, which may help to keep your breath free of bad odors.[4-6] Mix a few drops of tea tree oil in water to make a mouthwash, or try tea tree oil infused toothpicks as breath fresheners.

Treat toenail fungal infection. Fungal infections on toenails (onychomycosis) are quite common. Topical application of tea tree oil seems to be effective at eradicating this kind of fungal infection, and it may be as effective as prescription medications for the condition.[7-9] Try applying tea tree oil to a cotton ball and dabbing it on your toenails until the infection goes away.

Prevent dandruff. Studies show that tea tree oil can also be effective in treating dandruff. In one study, 5 percent tea tree oil applied daily for four weeks reduced symptoms of dandruff by 41 percent.[10] Try mixing tea tree oil with coconut oil, massaging it onto your scalp, and letting sit for a few hours (or overnight). Wash out using mild shampoo.
