Australian tea tree
Quick Summary
The Australian tea tree, primarily Melaleuca alternifolia, is a shrub or small tree native to eastern Australia. It belongs to the myrtle family and has aromatic evergreen foliage. Historically, Australian Aboriginal peoples used the plant medicinally, employing crushed leaves for respiratory issues and infusions for skin conditions.12
Today, tea tree oil, extracted from the leaves via steam distillation, is commonly used topically for various skin ailments like acne and athlete's foot, though scientific evidence for its effectiveness is limited. The oil is strongly aromatic, containing over 100 compounds, with terpinen-4-ol being a major component. While generally safe for topical use, it can cause skin irritation in some individuals and is not intended for ingestion.2
