About the Plant
The tamanu tree (Calophyllum inophyllum) is a tropical coastal tree known for producing seeds that yield tamanu oil, a deep green oil widely used in traditional medicine and skincare.
The oil is extracted from the kernels inside the fruit after they are sun-dried and cold pressed. Tamanu oil has long been valued for its ability to support skin repair and promote healthy-looking skin.
Because of its rich fatty acid profile and unique bioactive compounds, tamanu oil is often used in natural skincare formulations and healing balms.
