Fetau oil is a traditional remedy with a long history of use in the South Pacific. More commonly known as Tamanu oil, it's Greek name Calophylluyn means beautiful leaf.

Fetau oil is a significant topical healing agent with skin healing, anti-neuralgic, anti-inflammatory, antimicrobial and anti-oxidant properties.

Over the past few years, fetau oil has begun to infiltrate the European and US markets, primarily in cosmetic sectors.

For WIBDI, the interest came in 2008 from fair trade cosmetic retailer The Body Shop, who worked closely with the organisation on the virgin coconut oil project.

The fetau nuts are collected when they naturally fall from the tree. They are then gathered and laid out on racks to dry for the next two months. During this process, the kernels turn release a strong, rich oil.

The oil is then extracted via cold-pressing and filtration. It takes a large number of nuts to produce just a small quantity of oil, making the potency of the oil amazing.
