What is Benzoin Siam Gum
Benzoin Siam Gum is a natural aromatic resin obtained from the bark of the Styrax tonkinensis tree, which grows in Laos & Vietnam only. It is one of the most important natural resins used in the global fragrance, cosmetic, incense, and pharmaceutical industries.
Known for its warm, sweet balsamic aroma with soft vanilla-like undertones, Benzoin Siam Gum has been valued for centuries both as a traditional incense material and as a modern raw ingredient for fine fragrance formulations.
Origin of Benzoin Siam Gum
Benzoin Siam Gum is produced when the bark of the benzoin tree is carefully tapped or wounded. In response, the tree naturally secretes a protective resin. This resin gradually hardens when exposed to air, forming fragrant tears or lumps known as benzoin gum.
Vietnam is currently one of the leading sources of high-quality Benzoin Siam Gum due to its favorable climate, forest conditions, and long-standing tradition of resin harvesting.
