Είναι βότανο. Το κανονικό όνομα είναι Aquilaria agallocha.

There are several plants in Asia that are rare and endangered as well. A few of them include Agarwood, Aquilaria crassna, Paphiopedilum delenatii orchid and the Rafflesia arnoldii,

The wood is used in traditional Chinese medicine. Trees of the genus, not just of this species, when wounded and infected with certain fungi produce a resin-rich wood called aloeswood or oud, which is used in incense and perfumery. People often damage the trees in the hopes that they will produce such wood, which puts them at further risk.

Some of the tropical species of the genus are being cultivated in large numbers, but even so their wild populations are endangered. There may nowadays be some cultivation of A. sinensis as well -- I don't know -- but even this would not prevent damage to and cutting of existing trees by people seeking an illicit profit.

Agarwood (or just Agar) is the resinous heartwood from Aquilaria trees, which are large evergreens native to southeast Asia. Formation of agarwood occurs in the trunk and roots of trees that have been infected by a parasitc ascomycetous mold, Phaeoacremonium parasitica, a dematiaceous (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. 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.
