Agarwood actually originated from a tree species called Aquilaria.The treasured resin is formed as a result of a certain type of mold which infected the Aquilaria tree.
However, naturally only 7% of the Aquilaria trees that grow in the wild would be infected by the mold and turned into Agarwood. Today, this infection can be manipulated and synthesized via a biotechnology procedure called inoculation.
The wild Agarwood trees is an endangered species and protected worldwide by the Convention of International Trade in Endangered Species (CITES).
