Vetiver oil (vetiver essential oil)

Vetiver oil is hydrodistilled from the dried roots of Chrysopogon zizanioides. It is a complex oil: one study counts over 150 compounds, a review about 200.

Khusimol is among its most concentrated alcohols; the single molecule that gives vetiver its smell, a synthesis study showed, is a trace ketone. The house calls the oil smoky and rooty: our reading, not a source’s.

Vetiver roots, a tied bundle

A tied bundle of dried vetiver roots, the house’s own model. Modelled in-house (procedural, in Blender); its size is typical of the material, not a measurement; not a photograph or a scan.

To place it in your room, open this page on an iPhone or iPad (AR Quick Look) or an Android phone (Google Scene Viewer). The files below open in any 3D viewer.

A bundle of dried vetiver roots (Chrysopogon zizanioides), tied with jute: the fine, wiry, tangled roots of a tall grass, with their side rootlets, dug, washed and dried before they are distilled for vetiver oil. Modelled in-house; real bundles hold many more, finer roots than a phone model can carry.
