In short
Ho leaf oil is distilled from the leaves of a linalool chemotype of Cinnamomum camphora. It is a natural source of linalool and a common replacement for rosewood oil.
What Ho Leaf Oil smells like
Ho leaf oil, distilled from the leaves and branches of a linalool-rich chemotype of the camphor tree, is almost pure linalool — around 90% or more. It is fresh, floral and slightly woody, a little citrus-tinged, and less complex than true rosewood oil, which owes its depth to trace sesquiterpenes. It is widely used as a sustainable alternative to rosewood.

What makes Ho Leaf Oil distinctive
Natural linalool: softer and rounder than the synthetic, with a faint camphor reminder of its tree, but simpler than rosewood.
How Ho Leaf Oil is used
Used as a natural source of linalool and as a substitute for rosewood oil in perfumery.
Typical role: blender (smooths the joins between other materials).
How Ho Leaf Oil differs from similar materials
- Linalool
- Synthetic linalool is cleaner and simpler; ho leaf is softer and rounder, with a faint camphoraceous note.
- Rosewood Oil (Bois de Rose)
- Ho leaf is used as a rosewood substitute because both are linalool-led; rosewood is deeper and more layered, with a sweet-spicy woodiness. (compared directly by a cited source)
An asterisk marks a difference that a cited source states directly. The others compare the published descriptions of each material. Smell varies with grade, supplier and dilution; compare them side by side on blotters before substituting one for another.
Formulation considerations
Mostly linalool, which is declarable and can oxidise; store cold. Composition depends on the chemotype supplied.
