Vietnamese oud, also known as agarwood or calambac, has a rich and storied heritage that stretches back thousands of years. It is renowned for its unique fragrance and cultural significance, making it highly sought after in the global market. This article explores the history, conservation efforts, key regions, and international appeal of Vietnamese oud.
History of Vietnamese Oud
The use of agarwood in Vietnam dates back to the third century CE, with records in the Chinese chronicle «Nan zhou yi wu zhi» (Strange Things from the South) by Wa Zhen of the Eastern Wu Dynasty, which documents the collection of agarwood in the mountains of central Vietnam. By the 16th century, Vietnamese rulers like Nguyễn Hoàng actively promoted the trade of agarwood with neighboring countries, particularly China and Japan. During this period, varieties such as Calambac (known as «kỳ nam» in Vietnamese) and trầm hương were highly valued. The Nguyễn Lords even established a royal monopoly over the sale of Calambac, which became a significant source of revenue.
Important Vietnamese Agarwood Forests and Conservation Efforts
The most significant Vietnamese agarwood forests are predominantly located in the central and southern regions of the country. Key areas include:
Southern Coastal Regions: Adjacent to the Cambodian border, with notable locations like Phú Quốc Island.
Central Highlands: Regions such as Hà Tinh, Kon Tum, Quảng Nam-Da Nang, Bình Định, and Gia Lai.
Coastal Belts: Areas like Quảng Ninh, Hà Bắc, Hòa Bình, and Tuyên Quang.

The formation of oud resin occurs as a natural defense mechanism when Aquilaria trees are infected by certain fungi or experience physical traumas. Unfortunately, these natural forests are increasingly threatened by over-exploitation. To address this, the
The Vietnamese government has implemented several conservation strategies:
1. Legal Protections: Since 1996, Aquilaria crassna, the primary species from which agarwood is derived, has been classified as endangered and is protected under the Vietnam Red Data Book and CITES regulations.
2. Community Initiatives: Local communities, particularly in provinces like Hà Tinh, actively collect seedlings from natural forests to grow in home gardens and plantations. This initiative provides income for locals while reducing pressure on natural populations.
3. Vietnam Tree Seed Project: This project promotes the use of Aquilaria crassna in non-timber plantations as an ex situ conservation model. For example, a breeding orchard in Bố Trạch district, Quảng Bình province, helps provide improved seed sources for sustainable cultivation.
4. Sustainable Practices: Regions like Quảng Nam, Bình Định, and Kon Tum are at the forefront of expanding agarwood farms, implementing agroforestry systems, and promoting the use of microbial technology to induce agarwood formation. Companies such as Truc Lam Quan Tue are developing chemical-free agarwood products through innovative and sustainable methods.
