Tea tree oil is a natural essential oil derived from the leaves of the Melaleuca alternifolia plant, native to Australia. It is known for its antimicrobial properties, making it popular in skincare and household products. People often use it to help treat acne, dandruff, and minor cuts or infections. This oil can be applied topically, but it should be diluted with a carrier oil to avoid skin irritation. Tea tree oil is also used in aromatherapy and can be found in various products, including shampoos, lotions, and cleaning supplies, due to its pleasant scent and potential health benefits.
