Tea tree oil has strong anti-fungal, antiseptic and antibacterial properties, and is an important addition to every home’s medicine cabinet1,2. While there is some controversy over what it’s best for, there is little doubt about its usefulness. In popular practice it is used to ease many conditions: acne, fungal infections (athlete’s foot, nail fungus), minor skin abrasions, coughs and colds (as an inhalant), head lice, and as a topical disinfectant for skin and for household surfaces1,2,3,4,5,6.
