What does agalwood mean?
Agalwood is the aromatic, resin-saturated heartwood that forms inside certain Aquilaria trees after they are infected by mould. In response to the infection, the tree produces a dense, dark, fragrant resin, transforming otherwise pale, light wood into one of the most valuable natural materials in the world. Known more commonly today as agarwood or oud, agalwood has been burned as incense and distilled into perfume across the Middle East and Asia for many centuries, and it appears by name in ancient trade and religious texts. The word itself is now rare, surviving chiefly in older literature and specialist writing about perfumery, where 'agarwood' has become the standard English term. Because genuine resinous wood is scarce and increasingly protected by conservation laws, high-quality material commands extraordinary prices, and synthetic substitutes are common. For readers, agalwood offers a vivid example of how a botanical accident can create a commodity treasured across cultures.
nounA fragrant dark resinous heartwood formed in certain Aquilaria trees when they become infected with mould; it is prized as incense and as the source of oud perfume.
- The resinous, aromatic heartwood of Aquilaria trees, produced in response to fungal infection and highly valued in perfumery and incense.
- By extension, the perfume material or oil (oud) derived from this wood.
"The merchant opened the chest to reveal slabs of precious agalwood, their scent filling the room."
"In the souk, traders weighed curls of agalwood on brass scales while smoke curled from a burner nearby."
"Her favourite attar was distilled from aged agalwood, deep and smoky with a sweetness that lingered all evening."
Rarely pluralised; the uncountable singular is standard, since the wood is treated as a bulk commodity.
"Different grades of agalwoods were laid out for inspection at the auction house."
Agalwood is ordinary tree wood transformed by fungal infection into one of the most expensive raw materials on earth — ounce for ounce, it can outprice gold.

Etymology of agalwood
Agalwood entered English through trade routes connecting Europe with Southeast Asia, where the fragrant wood was harvested. It is generally understood as a variant form of 'agarwood', a name whose history passes through Malay and other Asian languages into European languages such as Portuguese before reaching English, likely in the early modern period. The word belongs to the same family of names as 'aloeswood' and 'lignum aloes', terms long used in European texts for this same Eastern aromatic wood, distinct from the bitter medicinal plant called aloe.
How agalwood is actually used
Agalwood is a rare, largely historical or specialist term; modern usage overwhelmingly favours 'agarwood' or 'oud'. It appears mainly in texts on perfumery, incense, and Middle Eastern or East Asian trade goods.
Easily confused with agalwood
Aloeswood is a traditional name for essentially the same resinous heartwood, but the two terms are used interchangeably rather than denoting different substances.
