Quick Summary

The tea tree, scientifically known as Melaleuca alternifolia, is a shrub or tree native to Australia. It belongs to the myrtle family and has aromatic, evergreen foliage. Historically, Australian Aboriginal peoples used the plant's crushed leaves and inhaled oils for medicinal purposes, treating respiratory and skin conditions.12

The essential oil derived from the tea tree's leaves, commonly called tea tree oil, is extracted through steam distillation. This oil has a strong, camphor-like scent and is used topically for various skin issues like acne, dandruff, and athlete's foot, though scientific evidence for its effectiveness is limited. Tea tree oil can cause skin irritation in some individuals and is not safe for ingestion.1
