Palo Santo

Sweet, resinous, and surprisingly citric — like frankincense crossed with lime peel, lit on a warm stone. Palo santo is the smell of a South American dry forest at dusk: dusty, aromatic, quietly sacred.

The Full Story
Extraction & Chemistry
Extraction method
Steam distillation of heartwood from naturally fallen, dead Bursera graveolens trees. The aromatic compounds develop during a post-mortem maturation period of three to five years as the wood decomposes on the forest floor — freshly felled green wood yields minimal fragrance. Oil yield is relatively low. Sustainable operations in Ecuador harvest only deadfall timber from managed dry forest plots.

In Perfumery
Palo san to functions as a base note with unusual top-note diffusion, owing to its high limonene content (approximately 51%). This dual character — citric brightness over resinous-woody depth — makes it structurally unique. It is a bridge between incense-sacral accords and fresh woody compositions. In amber and woody-ambery structures it contributes warmth without heaviness. Its frankincense-like resinous quality supports smoky and meditative compositions. The mentofuran content adds a cool, minty layered that lifts the overall profile. Palo san to is increasingly used in niche perfumery as an alternative to depleted sandalwood and restricted frankincense grades.
