Guaiac wood is derived from the heartwood of the guaiac tree (Bulnesia sarmientoi), native to South America. Known for its dense and resinous properties, guaiac wood has a long history of use in both traditional medicine and perfumery. In fragrances, it is valued as a versatile base note, imparting warmth, depth, and a subtle smoky quality to woody and oriental compositions.

Guaiac wood has a smooth, creamy, and slightly smoky aroma with warm woody undertones. Its scent is soft yet robust, featuring balsamic and resinous facets that add richness and complexity. Subtle leathery and spicy nuances contribute to its depth, while its slightly sweet and earthy character makes it an elegant and grounding note in perfumery.
