Formation of Gaharu Aromatic Resin
Formation of Agarwood or Gaharu Resin has been introduced over the past decades and can be classified as Natural
Inoculation, Traditional Inoculation & Artificial Inoculation.
In the past, agarwood or gaharu tree will only form resin due natural reaction to nature such as trees struck by
lighting, animal & insect attacks, forest fire, wind or storm damage and tree invaded by fungus. Resin produce
in this natural way requires a very long time, but such resin provides very natural and pure fragrant due to the
long period of incubation. Yield to obtain gaharu resin in this natural way are very low, only less than 7% from
Agarwood tree which has been naturally grown for more than 70 years.
Traditional Inoculation had been introduced a few decades ago. The methods being use are by physically damaging
the tree with nails, hammer, blades, drilling hole or fire damage. Some even apply toxic on the skin of the tree to
stimulate the tree. However, by using such methods, the yield is low and the quality is mostly of the lower grade
or inferior. Such resin have plain fragrant and has very small percentage of essential oil.
New techniques are discovered in this modern time and can be considered as Artificial Inoculation. This is
widely used in most Gaharu Plantation in Malaysia, China, India, Thailand, Vietnam, Indonesia, Cambodia,
Burma, Laos and etc. Artifical Inoculation consist of methods such as drilling holes and inserting fungal.
This method is fast and results can be seen within 12 to 24 months.
