What is Tamanu oil?

Tamanu oil is pressed from nuts of either Calophyllum inophyllum or Calophyllum tacamahaca , tropical trees belonging to the Calophyllaceae family. The nuts yield 70–75% the greenish-yellow inedible oil. The oil originates in Polynesia, where it continues to play an important cultural role. Commercial uses of tamanu oil are predominantly for skin care. The oil has both medicinal value and use as a fuel. Calophyllum inophyllum oil is rich in antioxidants and contains UV-absorption properties that can be used within the dermatology field. Tamanu oil has been found to have wound healing and antibacterial properties in low concentration, but is cytotoxic in high concentration.
