- medium
A cited maximum is a limit, not a suggested dilution. Missing restrictions do not establish safety.
The directly read NHR IFRA documentation reviewed in this pass does not classify this khella oil as phototoxic. A secondary vendor caution about sun exposure exists in public aromatherapy retail material, but no primary numeric phototoxic limit was found.
Contraindications & cautions

THE SCIENCE BEHIND THE SCENT
Inside the oil
An oil's character comes from its natural chemical composition. Explore each constituent to understand the connections.
About this composition
This record is anchored to NHR Organic Oils' 2024 GC/COA and companion 2024 specification sheet for Moroccan steam-distilled seed oil. That public batch is dominated by linalool and branched-chain isoamyl esters, with 2-methylbutyrate and isobutyrate derivatives materially outweighing the monoterpene hydrocarbons.

A TRADITION OF BOTANICAL CURIOSITY
Traditional & reported uses
These uses reflect the profile's reported traditions and literature. They are not established treatment recommendations.
- traditionally referenced in Mediterranean folk herbal tradition for respiratory and digestive comfort
- used in perfumery for its warm, herbaceous, slightly sweet facet
- reported to be used in diffuser blends for a grounding, calming atmosphere
- traditionally associated with easing occasional tension in aromatic folk practice
- shares the general umbelliferous-seed-oil reputation for warming, comforting aromatic use
- used in niche perfumery blends as a distinctive herbaceous note

What we're still learning · 3 data gaps
Good decisions start with knowing what is — and isn't — in the evidence.
- CAS could not be verified in this pass from a primary source for amyl valerate, so that field remains null.
- Odor intensity 65 is an archive normalization from public qualitative odor descriptions rather than a directly published 0-100 measurement.
- No public source located in this pass gave directly measured volatility-rate or tenacity-hour values.
