In short
Agarwood oil, known as oud, is distilled from agarwood — resin-infused heartwood that forms in Aquilaria trees in response to infection. It is one of the most expensive and variable perfumery materials.
What Agarwood Oil (Oud) smells like
Oud (agarwood) oil is consistently described as woody, smoky and animalic: a perfume dictionary calls it animalic, earthy, dark and rich-woody; others add leathery and balsamic nuances and slightly sweet undertones. It smells different depending on age and origin, and grades range from sweet to smoky to animalic; a 'barnyard' character attributed to fermentation appears only in weaker sources.

How Agarwood Oil (Oud) is used
Used in traditional attars and in oriental, woody and leather compositions.
Typical role: backbone (used in large proportions as a structural material of an accord); fixative (slow to evaporate; helps a blend last and holds lighter notes).
How Agarwood Oil (Oud) differs from similar materials
- Cypriol Oil (Nagarmotha)
- Cypriol is a drier, cold-smoky earth often used to suggest oud; oud is more animalic and balsamic.
- Ambrocenide
- Ambrocenide is a mineral ambergris sometimes compared to oud; oud is the darker, animalic natural wood. (compared directly by a cited source)
- Black Agar Givco 215/2
- Black Agar Givco is an oud replacer built on olibanum and amber, brighter and without the animalic side.
An asterisk marks a difference that a cited source states directly. The others compare the published descriptions of each material. Smell varies with grade, supplier and dilution; compare them side by side on blotters before substituting one for another.
Formulation considerations
Aquilaria species are listed in CITES Appendix II, so international trade needs permits. Adulteration is common; buy from documented sources. No single CAS number is given because composition varies so widely.
