Section 1: The Origins & Science of Tea Tree Oil
1.1 A Healing Legacy: Aboriginal Roots & Global Adoption
For over 60,000 years, Bundjalung Aboriginal people in Australia crushed tea tree leaves to:
- Treat wounds and prevent infection
- Relieve coughs and colds
- Soothe skin irritations
Western medicine took notice in the 1920s when Australian chemist Arthur Penfold documented its antiseptic properties 11 times stronger than phenol (a common disinfectant).
1.2 How Modern Tea Tree Oil Is Produced
High-quality tea tree oil undergoes:
- Sustainable harvesting – Leaves hand-picked from pesticide-free trees
- Steam distillation – Releases oil while preserving active compounds
- GC/MS testing – Verifies purity (look for ≥30% terpinen-4-ol, the key antimicrobial component)
Pro Tip: Avoid oils labeled “fragrance” or “perfume”—these are diluted synthetics.
