LIGNUM ALOES also known as aloes wood, agar wood agarci wood, eagle wood, oud, ud etc.
This is sweet perfumed wood from the Aquilla tree, which is native to India and surrounding areas. One of the most ancient and traditional incense woods, celebrated in biblical texts (ie the Song of Solomon) simply as "Aloes". The unique aroma is due to a fungal infection of the heartwood, which causes the tree to secrete an aromatic protective resin. The Japanese have identified six grades of this wood, as it changes with age and degree of infection. The top grade (old wood, where practically everything has decayed except the infected part) is very rare, and very, very expensive. Moreover, to confuse matters, the lower grades smell totally different to the top ones.
Because of its value Aloes wood is frequently faked by adding synthetic oils to a common wood -then sealing them in with a neutral gum or resin.
Not to be confused with Aloes Resin!
