Agaru (Aquillaria Agallocha)
0 comments

This is a large tree that may reach heights of 60 to 80 feet and has a thick trunk that is 3 to 4 feet in diameter. It is indigenous to Southeast Asia. The bark is papery thin and was once used for writing in the same way that Betula utilis tree bark (Bhojpatra in Sanskrit) was. The leaves are leathery thin, glossy, and up to 3 inches long. Flowers are white, and the fruit is about 1 to 2 inches long, smooth, and thin.

In 7 to 8% of the trees, the bark becomes infected with a fungus (Phaeoacremonium parasitica), which causes the bark to transform from light brown to dark brown or black. Because of the presence of oleoresin, this results in a distinct smell specific to the Agaru tree.

This afflicted section of the tree produces Agarwood oil, which is sold in Arabia, China, and Japan. This tree's oil has a great economic worth because it is incredibly expensive, frequently costing the same as 24-carat gold. The reason for this is the time-consuming distillation process, which yields only 30 cc oil from 100 kg of infected wood. The oil is known as Oud and is made entirely of natural essential oils.

The aroma is mostly due to various sesquiterpene and epoxide mixtures, which can also be employed as pheromones to attract the opposite gender.

General Information

The genus Aquilaria contains approximately 17 species, 8 of which are known to produce Agar oil. Aquilaria agallocha is a synonym for Aquilaria malaccensis and Aquilaria secundria.

Agarwood is well-known for its use in the production of incense sticks for various ceremonies. Beautiful carvings and sculptures are also made from the wood. Agarwood beads are created in several Southeast Asian countries to ward off evil spirits and provide good luck.

Special Note

Agarwood Oil

Agarwood oil is extracted from the tree's resin. The plant's resin is known as Gaharu. It forms spontaneously as a result of the tree's reaction to a fungus attack. To defend the wounded region, attacked trees exude fragrant gum, which hardens into a resin. The precious oil is trapped within the Resin in the hardened area. The oil is extracted from this resin.

Habitat of the Plant

This tree is indigenous to Southeast Asia, where it can be found in China, Bangladesh, Bhutan, Eastern India, Thailand, and Malaysia.
