Agarwood, is a fragrant dark resinous wood of tree species of Aquilarialike A. malaccansis and A. crassna (Thymelaeaceae)used in high grade incenses, perfumes, and small carvings. It is formed in the heartwood when they become infected with a type of mold (Phialophora parasitica) an as the infection progresses, the tree produces a dark aromatic resin, called aloes (notof Aloe) or agar (not algal based) due to which the heart wood becomes dark and resin-embedded. This wood is much valued for its distinctive fragrance, and thus is used for incenses and perfumes. First-grade agarwood is one of the most expensive natural raw materials in the world, costing as high as US$100,000/kg,with inferior grades fetching lesser prices. The current global market for agarwood is estimated to be in the range of US$6 – 8 billion and is growing rapidly
