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
Liberty Natural Products directly verifies this oil as a wildcrafted, steam-distilled Achillea millefolium from the United Kingdom with a vivid blue appearance and sweet-herbaceous odor, but its public UK COA does not list constituent percentages. To avoid fabricating chemistry, the constituent table below is populated from a directly readable commercial blue-yarrow profile for the same species and blue chamazulene-rich style, while preserving the UK-specific provenance only for top-level identity and sensory fields.

What we're still learning · 3 data gaps
Good decisions start with knowing what is — and isn't — in the evidence.
- A public UK batch GC/GC-MS or COA with constituent percentages for Liberty Natural's Product No. 266 was not found in this pass; a directly readable blue-yarrow constituent profile for the same species was used to avoid leaving the file empty or inventing UK-specific numbers.
- A public CAS source for artemisia ketone was not verified in this pass, so its CAS is left null rather than guessed.
- Odor intensity 65 is an archive normalization of generic yarrow's qualitative "Medium - Strong" aroma strength rather than a native published 0-100 measurement.
