Tea tree oil, derived from the leaves of Melaleuca alternifolia, has a long history of use in traditional Australian medicine and has become one of the most widely studied essential oils in modern research. Studies indicate that its naturally occurring compounds, particularly terpinen-4-ol, demonstrate notable antimicrobial and anti-inflammatory properties, which may help explain its traditional applications for skin concerns. Research suggests that topical tea tree oil formulations show promise for mild to moderate acne, minor wound care, and supporting nail health, with several clinical trials reporting outcomes comparable to some conventional topical treatments. As with all essential oils, tea tree oil is intended for external use only and is typically diluted in a carrier oil, since undiluted application may cause skin irritation in sensitive individuals.
