What turns wood into oud?

Oud is fragrant, resin-rich wood from certain trees, notably the genera Aquilaria and Gyrinops. Resin develops as part of the tree’s response to stress or injury. Ordinary wood and resin-rich agarwood are therefore not the same material.

Agarwood-producing trees occur across parts of South and Southeast Asia. Each species has its own range, so a country name alone does not identify the tree.

Natural, cultivated or enhanced?

Cultivated describes trees that were planted; resin formation may be induced. Enhanced is a commercial term that can refer to treatments applied after harvest. These descriptions address different stages.

Natural also needs clarification. Does the seller mean unperfumed wood, or a wild tree? Ask separately about cultivation, resin induction and subsequent processing.

Read the name. Then look further.

“Royal”, “Triple” and “VIP” help retailers distinguish selections, but do not offer a reliable comparison across sellers on their own. Find out what the term means for the product in front of you.

Ask about the batch, not just the name.

Look for actual photos, a clear description of processing and a sample when available. Origin is one part of the story; experiencing the aroma is another.
