Oodh - ഊദ് :
Formation of agarwood occurs in the trunk and roots of trees that have been infected by a parasitc ascomycetous mold, Phaeoacremonium parasitica adematiaceous (dark-walled) fungus. As a response, the tree produces a resin high in volatile organic compounds that aids in suppressing or retarding the fungal growth, a process called tylosis. While the unaffected wood of the tree is relatively light in colour, the resin dramatically increases the mass and density of the affected wood, changing its colour from a pale beige to dark brown or black. In natural forest only about 7% of the trees are infected by the fungus. A common method in artificial forestry is to inoculate all the trees with the fungus.

Commercially used fragrant-resinous agar wood is formed in the interior of the old tree. The tree contains plenty of oleoresin and has irregular dark patches. The wood burns with a bright flame giving off a pleasant smell .
