A plain-language guide to agarwood, oud, and why this resinous wood is so valued.

Agarwood is resin-infused heartwood. Many people think it is a tree species you can simply cut and sell. It is not. It is what happens when a tree of the Aquilaria genus is wounded — by weather, insects or a deliberate, controlled process — and defends itself by producing a dark, fragrant resin. Pale wood is just wood. Wood carrying enough resin becomes agarwood.
That single fact explains most of the trade: why every piece differs, why photos and measurement matter, and why honest sellers state facts (gram weight, bead count, oil lines, sinking or not) instead of adjectives.
The tree lays down resin along its fibre as a defence response, guided by fungal activity. Over months and years the resin spreads, darkening the grain. The best material — dense, oily, layered in scent — comes from trees that were stressed early and left to mature. Induction can be encouraged in plantations; it cannot be rushed without cost to quality.
Mostly yes, with a regional accent. Agarwood is the common English term for the resinous wood and the tree. Oud (from Arabic) usually refers to the same material, and often specifically to the oil distilled from it or to the fragrance tradition around it. In a shop, "oud oil" and "agarwood oil" can mean the same product. English-speaking buyers searching "oud" and "agarwood" are looking at the same family of goods from two directions.
Three reasons, none of them marketing: it takes years to form, wild supply is scarce and regulated, and much of the volume weight is a natural material you cannot fabricate. Aquilaria species are listed in CITES Appendix II, so legal cross-border trade depends on cultivation and correct documentation. Plantation material is not a compromise — it is the sustainable, traceable route that the sustainable trade depends on.
A higher grade is not automatically the right one. For a first bracelet or for everyday heating, non-sinking or semi-sinking material often delivers the best experience per unit of budget.
We grow and process our own material in Hainan, China, including the Qinan No.1 cultivar selected from the Jianfengling lineage. Our Beijing flagship store in Songzhuang International Art District carries the traditional incense-shop name Liu Family Select Sandalwood & Agarwood, and our grading is stated in writing on every quotation.
Agarwood is resin-infused heartwood of Aquilaria trees. Resin forms as a defence response to wounding; the scent comes from the resin, not the pale wood.
Largely yes. Agarwood is the common English term for the wood and tree; oud (Arabic) often refers to the same material and especially the distilled oil or the fragrance tradition.
It forms slowly over years, wild supply is scarce and CITES-regulated, and the resinous portion cannot be manufactured. Cultivated, traceable material is the sustainable route.
