Agarwood oil (oud oil)
Agarwood oil is distilled from agarwood, the resin-laden heartwood that forms in Aquilaria trees after wounding or fungal infection. A review puts natural formation at 25 to 30 years.
Sesquiterpenes are its key constituents, agarospirol among the characteristic ones. Much agarwood is now induced in cultivated trees by fungal inoculation or wounding.

The record
Each field carries its evidence: open a chip for the source, the quoted words and the confidence. A field with nothing behind it says so and stays empty.
- Name
- agarwood oil (oud oil)
documented
Agarwood’s essential oils are intricate blends of volatile substances, such as monoterpenes and sesquiterpenes, and aromatic substances, such as phenyl ethyl chromones.

confidence B
- Part
- agarwood: the resin-laden heartwood
documented
Agarwood, also known as oud, aloeswood, or gharuwood, is a fragrant dark resinous wood formed in the heartwood of Aquilaria trees, particularly when they are wounded or infected by a fungus.
