Understanding the material
Biolandes documents both distilled and CO₂ agarwood products from Aquilaria crassna. The fragrant wood forms as the tree produces resin in response to damage or infection. Species, source and processing influence the supplied material. A perfume marketed as oud may instead use a constructed accord, so its name cannot establish natural agarwood content or traceability.
Compare an oud-described fragrance with a dry woody perfume. Separate resin, leather and smoke associations: the material need not foreground all three.

Continue with Labdanum, Sandalwood, Guaiacwood. These connections are comparisons for studying finished fragrances, rather than mixing instructions.
Technical references
Supplier references describe their specific materials. The botanical image is illustrative and does not certify species, provenance, grade or ingredients in a finished perfume.
