In recent years, Tamanu oil has gained global recognition in skincare, haircare, and holistic wellness circles.

In this guide, we will explore everything you need to know about Tamanu oil—its nutrition profile, science-backed health benefits, side effects, usage methods, dosage, storage, and precautions—so you can decide if it’s right for you.
What Is Tamanu Oil?
Tamanu oil is a thick, dark green oil extracted from the nuts of the Calophyllum inophyllum tree, commonly known as the Tamanu tree. This tree is native to Southeast Asia, the South Pacific islands, parts of Africa, and India’s coastal regions.
The oil is traditionally obtained by cold-pressing sun-dried Tamanu nuts. Unlike many other oils, Tamanu oil has a strong, earthy, nutty aroma and a slightly sticky texture. While the smell may be intense at first, it’s a sign of the oil’s potency and purity.
Tamanu oil is unique because it contains calophyllolide, a rare compound known for its anti-inflammatory and wound-healing properties. This makes it especially valuable for skin repair, scar healing, and managing chronic skin conditions.
Traditionally, Tamanu oil has been used to:
- Heal cuts, burns, and insect bites
- Treat eczema, psoriasis, and fungal infections
- Reduce joint pain and inflammation
- Promote hair and scalp health
