Oud is the fragrant resin produced by certain trees of the Aquilaria genus to protect themselves against the spread of a fungus named Philiaphora Parasitica. Used in India and the Arabian Peninsula since ancient times, oud appears in the Bible as a funeral perfume while in China, this "eagle wood" is still used in traditional medicine to activate the circulation of qi. Now threatened by overexploitation, its cultivation, sale and use are rigorously controlled. The oud we use has a CITES certificate, guaranteeing that its production and sale do not harm the conservation of biodiversity and is based on the sustainable use of wild species
