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.

Plant Description :
A large evergreen tree about 21 m in height and 1.5-2.4 m in girth with somewhat straight and fluted stem; leaves linear-lanceolate to ovate-oblong, 5-9 cm long, silky glossy and faintly parallel nerved; flowers small, greenish on very slender pilose petioles in shortly peduncled umbels, on younger branchlets, perianth about 5 mm long, slightly hairy outside, stapens alternate the perianth, filaments red at the apex, ovary tawny-tomentose; fruits slightly compressed, yellowish tomentose capsules. 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 .

Chemical Composition : 
The normal wood yields and essential oil which contains selinene, dihydroselinene, two unidentified sesquiterpene-hydrocarbons. agarol, a sesquiterpene alcohol, a hydroxy ketone. five isomeric decenes and rhombic as S-isopropyl-7-methyl- 5,5.5a, 6.7. 8-hexahydro-3H-naphtho.
