Tea tree oil may help treat infected skin wounds
In 2009, researchers found that mixing tea tree oil with silver significantly increased their antimicrobial activity against bacteria that causes skin infections. Separately, both agents are also effective in treating bacterial infections, but the scientists found they were much more effective when used together. Combining the two agents also minimized side effects that occur when each was used by itself.

Tea tree oil can be used to treat acne
In the 1990s, researchers studied the efficacy of 5 percent tea tree oil in treating acne, compared to 5 percent benzoyl peroxide lotion, and found that both significantly improved acne in study participants. Though the tea tree oil takes longer to work, it has fewer side effects than the benzoyl peroxide.

Tea tree oil, combined with butenafine hydrochloride, has also been found to effectively treat a fungal nail infection. Researchers created a cream with 2 percent butenafine hydrochloride and 5 percent tea tree oil, and then treated 40 of 60 participants with the cream. They found that 80 percent of patients using the medicated cream were cured.

Researchers have found that tea tree oil is an effective treatment for athlete’s foot, or tinea pedis. One study looked at 104 patients divided into three groups – a treatment of 10 percent tea tree oil group, a 1 percent tolnaftate group and a placebo group. The tea tree oil group and the tolnaftate group showed equal improvements in athlete’s foot symptoms.
