What is Agarwood?
Agarwood (also known as agar, aloeswood oud wood, oudh wood, eaglewood, or agar wood.) is a rare and precious wood formed from a type of tree in the Aquilaria genus. The Aquilaria tree is a large, towering species that can reach up to 30 meters in height.
Oud wood is formed through the infection of a specific fungus called Phialophora parasitica. This fungus infiltrates the trunk of the Aquilaria tree through wounds, leading to the production of a distinctive fragrant resin. This fragrant resin gradually accumulates within the trunk of the Aquilaria tree, giving rise to oud wood.
Formation of Agarwood
Agarwood is formed through the infection of a fungus called Phialophora parasitica. This fungus infiltrates the trunk of the Aquilaria tree through wounds, such as cuts, cracks, insect holes, etc., and produces a distinctive fragrant resin. This fragrant resin gradually accumulates within the Aquilaria tree trunk, forming oud wood.
Formation Process Due to Fungal Infection
Infection Process:
- The fungus Phialophora parasitica infiltrates the Aquilaria tree trunk through wounds, such as cuts, cracks, insect holes, etc.
- This fungus develops and reproduces inside the Aquilaria tree trunk, secreting toxic substances.
- These toxins stimulate the Aquilaria tree to produce a distinctive fragrant resin as a defense mechanism against the fungal invasion.
Resin Accumulation Process:
- This fragrant resin gradually accumulates within the Aquilaria tree trunk, forming agarwood.
- The time it takes for oud wood to form depends on various factors such as the type of Aquilaria tree, the type of fungus, environmental conditions, etc.
- Typically, oud wood takes 10 to 20 years to form.
Formation Process Due to Infection by Bacteria or Viruses
Besides fungi, certain bacteria and viruses can also contribute to the formation of agarwood, although this method is less common.
Formation Process Due to Bacterial Infection:
- Bacteria invade the Aquilaria tree trunk through wounds, then produce toxic substances.
- These toxins stimulate the Aquilaria tree to produce a distinctive fragrant resin as a defense mechanism against bacterial invasion.
- This fragrant resin gradually accumulates within the Aquilaria tree trunk, forming oud wood.
Formation Process Due to Viral Infection:
- Viruses invade the Aquilaria tree trunk through wounds, causing physiological disorders in the tree.
- These physiological disorders stimulate the Aquilaria tree to produce a distinctive fragrant resin as a defense mechanism against viral invasion.
- This fragrant resin gradually accumulates within the Aquilaria tree trunk, forming agarwood.
Types of Agarwood
Aloeswood is classified based on various criteria, including color, luster, density, etc. Some common types of oud wood include:

Preservation of Agarwood
Challenges in preserving agarwood
Agarwood is a rare and economically valuable wood with high medicinal significance. However, Oudh Wood is facing numerous challenges that threaten its survival.
Over-exploitation
Over-exploitation is the most significant challenge in preserving oudh wood. Being a rare and economically valuable wood, excessive exploitation has led to a depletion of agarwood reserves.
Currently, oudh wood is extracted through various methods, including natural extraction, manual extraction, and industrial extraction. Natural extraction involves traditional methods, using manual techniques to extract agarwood from infected Aquilaria trees. Manual extraction is done using primitive tools, while industrial extraction employs modern machinery.
Over-exploitation of oudh wood leads to severe consequences, including:
- Depletion of Aloeswood reserves: Excessive exploitation causes a continuous decline in oudh wood reserves, increasing the risk of oudh wood extinction.
- Environmental impact: Improper manual and industrial oudh wood extraction adversely affects the environment, leading to deforestation and environmental pollution.
- Transformation into criminal activities: Illegal oudh wood extraction has become a criminal activity, jeopardizing law and order.
Deforestation
Deforestation is another significant challenge in preserving agarwood. oudh wood is primarily formed in virgin forests, and deforestation results in a reduction of oudh wood reserves.
Currently, virgin forests in Vietnam are severely destroyed, mainly due to illegal logging and hydropower construction. Deforestation narrows the habitat of Aquilaria trees, leading to a decreased likelihood of agarwood formation.
Conservation Solutions
To preserve agarwood, there needs to be collective efforts from all levels, sectors, and society. Some conservation solutions include:
- Enhancing awareness through education about the importance of oudh wood conservation.
- Strengthening control to prevent illegal oudh wood exploitation activities.
- Reforestation to restore the natural habitat of Aquilaria trees.
- Developing sustainable oudh wood cultivation models.
Other Challenges in Agarwood Conservation
Besides the mentioned challenges, oudh wood faces additional obstacles, such as:
- Climate change: Negative environmental changes, including those in forest environments, may affect the growth and development of Aquilaria trees, reducing agarwood formation.
- Competition from other plant species: The high economic value of oudh wood may lead to the exploitation of other plant species, creating competition and reducing the survival chances of oudh wood.
To effectively preserve agarwood, close coordination is required among all levels, sectors, and society. Conservation measures should be implemented systematically, efficiently, and adapted to the current situation.
Conclusion
Agarwood (oud) is a rare and highly valued wood with significant economic, medical, and cultural importance. Eaglewood is formed through the infection of a fungus called Phialophora parasitica. This fungus infiltrates the trunk of Aquilaria trees through wounds, subsequently producing a distinctive fragrant resin. This resin accumulates gradually in the Aquilaria tree trunk, forming Eaglewood.
Eaglewood has a distinctive fragrance and is used in various fields such as:
- Medicine: Eaglewood has anti-inflammatory, analgesic, antibacterial, antifungal properties, and also acts as a tranquilizer, reducing stress.
- Fragrance: Agarwood is a crucial ingredient in fragrance production. Its fragrance is highly valued, being one of the rarest scents globally. Eaglewood is used to create fragrances for products like perfumes, essential oils, and incense.
- Cosmetics: Agarwood is used in cosmetics for its fragrance and skin-nourishing properties. The relaxing aroma of Eaglewood contributes to mental well-being, while its skincare benefits leave the skin soft and smooth.
Furthermore, besides medicine, fragrance, and cosmetics, agarwood is also utilized in other areas such as:
- Furniture: Eaglewood is employed in crafting high-end furniture products, adding a touch of luxury and sophistication.
- Jewelry: Eaglewood is used in crafting jewelry items like bracelets and rings, bringing high aesthetic value.
- Religion: Eaglewood is used in religious ceremonies, providing a pure and fragrant ambiance, and fostering a connection with nature.
Agarwood is a precious natural resource with its value manifested in various aspects:
- Economic Value: Eaglewood holds high economic value, reaching up to billions of currency units.
- Medical Value: Eaglewood has diverse medicinal properties, used in numerous traditional remedies.
- Cultural Value: Eaglewood is employed in various cultural practices, adding aesthetic and spiritual value.
However, Eaglewood is currently facing over-exploitation, leading to a depletion of its reserves. The main cause of this situation is the increasing demand for agarwood, coupled with limited supply.
To preserve Eaglewood, comprehensive solutions are necessary, including:
- Enhancing Awareness and Education: Increase public awareness of the value of Eaglewood to reduce illegal harvesting.
- Strengthening Agarwood Harvest Control: Intensify checks and monitoring of Eaglewood harvesting activities, imposing strict penalties for violations.
- Reforestation and Habitat Restoration: Plant and protect forests to create a suitable habitat for Aquilaria trees, thereby enhancing agarwood reserves.
