Agarwood is created when Aquilaria trees, which were traditionally planted around villages for their Feng Shui properties, are damaged, allowing a mould to attack the timber. When harvested, the infected, dark, resinous wood is pared away from the healthy, scentless, cream-coloured wood. The resin is especially coveted for its use in perfume and incense. Agarwood resin is distilled to create Oud oil, which is an essential ingredient in high-end perfumes.
