Its leaf oil is rich in citral — a geranial–neral mixture making up 65–85% — which gives the signature fresh-citrus note; the oil is a cornerstone of the fragrance industry and is being studied clinically for oral health and for controlling bacterial–fungal biofilms.

The leaves contain 1–2% oil; under standard ISO 4730, commercial tea tree oil must have at least 30% terpinen-4-ol and no more than 15% 1,8-cineole. The oil is used as an antiseptic, for skin and acne care, hair care, as an antifungal and as a natural cleaner. IUCN lists it as Least Concern (LC).
