Agarwood is a tree that is important to many different cultures as it is the main source of incense. The bark of the tree is peeled off to reveal the inside and then the tree is left to to be infected by a mold. The mold causes the tree to produce a resin to counter the mold. Where as before the resin the bark of the tree was colorless and odorless, the resin-filled tree now looks dark brown and has a nice fragrance. The resin filled bark is used as incense in many different eastern cultures, one of which are the Arabs.

Bukhoor is the Arabic word for incense. It's used by many Arabs to perfume their households and clothing. I grew up with it all my life but never thought of how this type of wood gives an aroma when burned that is so different from any other type of wood.

Resin has seen many different uses. Resin is used to make varnish for wood floor or other types of materials. It's also used to make adhesives such as epoxy glue. Another material that is made with resin is the glazing agent that is used on food to give them the waxy and shiny look.

Resin has a high resistance to environmental degradation as well as water degradation. This means it is excellent for boats because it can protect the wood from absorbing any water for a very long time.

Resin is a very good adhesive. In engineering, most of the resin used is epoxy resin which is a synthetic material. It is mostly used as an adhesive for building aircrafts as well as automobiles.
