Aloeswood, also known as agarwood, is a fragrant dark wood that forms in the heartwood of certain trees in the Aquilaria genus. This wood is highly valued for its aromatic properties and is often used in incense, perfumes, and traditional medicines. The formation of aloeswood occurs when the tree becomes infected with a specific type of mold, leading to the production of a dense, resinous substance. Due to its rarity and high demand, aloeswood is considered one of the most expensive woods in the world. It has been used for centuries in various cultures, particularly in Middle Eastern and Asian traditions, for spiritual and therapeutic purposes.
