In this guide, we will explore everything you need to know about Cajeput Oil — what it is, its science-backed health benefits, side effects, dosage, usage methods, precautions, and more.
What is Cajeput Oil?
Cajeput Oil is an essential oil extracted from the fresh leaves and twigs of the cajeput tree, scientifically known as Melaleuca cajuputi. The tree belongs to the Myrtaceae family, which also includes tea tree and eucalyptus.
The oil is obtained through steam distillation and is typically clear or pale yellow with a strong, camphor-like scent. Because of its active compounds such as cineole (eucalyptol), alpha-terpineol, and limonene, Cajeput Oil has been traditionally used as a natural antiseptic, expectorant, analgesic, and insect repellent.
Historically, it has been used in Indonesia, Malaysia, Vietnam, and other parts of Southeast Asia to treat respiratory infections, joint pain, digestive issues, and skin problems.
