Tea tree essential oil is antiseptic, antibiotic, antiviral, and antifungal — making it useful for a wide range of conditions. It’s used in the treatment of various infections, including candida, ringworm, and athlete’s foot, as well as for toothache, sunburn, cuts and grazes, and various skin conditions, including acne. It could also be incorporated into mouthwashes and hair shampoos.
Tea tree oil is widely used as an insect repellent and to treat insect stings. Although the aroma is not to everyone’s taste, it can easily be disguised with other essential oils for use in room diffusion methods when someone in the household has a contagious airborne infection.
