Agarwood - A Scent more valuable than Gold

Agarwood or Gaharu as it is known in many Asian countries is a resinous heartwood that sometimes occurs in trees belonging to the genus Aquilaria  (Thymelaeceae family). Aquilaria is a fast-growing, archaic subtropical forest tree, with a population range stretching from South Asia’s Himalayan foothills, throughout Southeast Asia, and into the rainforests of Papua New Guinea. It grows at elevations from a few meters above sea level to about 1000 meters, with approx. 500 meters being most ideal. Aquilaria can grow on a wide range of soils, including poor sandy soil. Seedlings require a great deal of shade and water but will grow rapidly, producing flowers and seeds as early as four years old. At least fifteen species of Aquilaria are known to produce the much sought-after agarwood. In South Asia, particularly India, Aquilaria achalloga is found. Aquilaria malaccensis is mostly known from Malaysia and Indonesia, while Aquilaria crassna grows primarily in Indochina. A number of others are also known, such as Aquilaria grandfolia, Aquilaria chinesis etc., though these are relatively minor species for agarwood production.

 

Agarwood Value

The value of first-grade Agarwood is extremely high. A wide array of products of different grades is available on the market, varying with geographical location and cultural deposition. Prices range from a few dollars per kilo for the lowest quality to over fifty thousand US dollars for top quality oil and resinous wood. Aquilaria crassna is listed as a critically endangered species in Viet Nam, and A. malaccensis is listed as vulnerable by the World Conservation Union, IUCN.

Agarwood Extinction

Resin-producing agarwood trees are endangered throughout their known habitat all across Southeast Asia. The main driving force, which initiated this project, was the recognition of unsustainable Aquilaria harvesting in natural forests that resulted in the near extinction of this tree genus in Viet Nam and elsewhere. Aquilaria crassna is now a protected species in Viet Nam. Trade and harvesting restrictions will be virtually impossible to implement and enforce if no alternative is developed to forest-based harvesting. In addition, both in the short and long-term, a natural resource base needs to be maintained to supply present and future Aquilaria plantations with genetic source material in order to prevent plant decease, maintain diversity, and possibly improve resin production.

Agarwood Substitutes

Development of synthetic agarwood substitutes usually arises when sustainable supplies of the natural product are not available. One of the first questions pursued when contemplating the pilot project was, “Is it possible to synthesize agarwood and agarwood oil?” The answer is a qualified no. Agarwood cannot be synthesized. Chemical substitutes are already available for perfume; these are cheap and constitute the least profitable end of the market. In addition, these products do not come close in emulating the natural product and thus do not pose a threat to producing non-synthetic agarwood products. The major chemical components responsible for the characteristic scent of agarwood products, 15-carbon chain compounds called sesquiterterpenes, can in principle be synthesized. However, these are very complicated structures that are extremely expensive to synthesize, which makes it commercially unattractive.

Agarwood Essential Oil – Oud Oil

Known also as Oud oil, agarwood is one of the most precious, rare and certainly most expensive essential oils in existence today. Agarwood is sometimes called Gaharu. The essential oil is derived from the heartwood of the agarwood tree. There are a number of popular species but typically aquilaria malaccensis, aquilaria agallocha or Aquilaria crassna are used to make the oil. Agarwood is native to India as well as several areas of South East Asia including Vietnam, the Philippines and Indonesia.
