Aetoxylon sympetalum, commonly known as "agarwood" or "eaglewood," is a type of tree native to Southeast Asia, particularly found in countries like Vietnam, Indonesia, Malaysia, and others. The tree is valued for the resin it produces, which is highly prized for its aromatic qualities and is used in various cultural, medicinal, and religious practices.

Agarwood is renowned for the fragrance it emits when burned and is considered one of the most expensive raw materials used in perfumery and incense-making. The resin is formed in the tree as a response to injury or infection, leading to the formation of a dark and highly aromatic resinous wood.
