Tea tree essential oil, derived from Melaleuca alternifolia, is a staple in aromatherapy and natural skincare and is valued for its powerful antibacterial, antifungal, and antiviral properties. Native to Australia, it deeply cleanses oily and acne-prone skin, reducing redness and swelling and promoting a clearer complexion. In cosmetics, it is often combined with carrier oils to balance sebum production and improve skin health. Its cleansing effects also extend to hair care, soothing irritated scalps and controlling dandruff. In addition to nourishing the skin, tea tree oil purifies the air, aids in oral hygiene by fighting canker sores, and is effective against fungal infections and athlete's foot. Its acaricidal and insecticidal properties also make it a natural repellent against ticks and lice.
