Cited dermal maximum · leave-on: 8.6%
Phototoxicity: Not flagged in this profile
Oxidation risk: medium

A cited maximum is a limit, not a suggested dilution. Missing restrictions do not establish safety.

No furocoumarin-based phototoxic restriction was identified in the reviewed high-chamazulene blue yarrow sources.

Contraindications & cautions

moderateEden Botanicals advises avoiding this oil with small children, the elderly, people with epilepsy, and during pregnancy or nursing because it contains a small amount of thujone.
moderateAromaWeb summarizes Tisserand and Young as noting possible neurotoxicity for yarrow essential oil and recommends a dermal maximum of 8.6%.

About this composition

This record combines a current Eden Botanicals product page for high-chamazulene blue yarrow identity with public quantitative composition from high-azulene Achillea millefolium literature. Eden explicitly states this organic Italian steam-distilled style contains approximately 17% chamazulene and names sabinene, beta-pinene, beta-caryophyllene, germacrene D, and 1,8-cineole as notable co-constituents. To avoid inventing the remaining percentages, the table below anchors numeric ranges and typical values to published high-chamazulene yarrow studies and a public Blue Yarrow standard.

What we're still learning · 4 data gaps

Good decisions start with knowing what is — and isn't — in the evidence.

The current Eden public page names several notable co-constituents but only quantifies chamazulene directly; the remaining numeric constituent values are anchored to public high-chamazulene yarrow literature and a Blue Yarrow standard rather than an Eden batch COA.
The stored odor_intensity 70 is an archive normalization from Eden's qualitative aroma description and top/middle note placement, not a source-native 0-100 sensory score.
A public primary CAS source for the grouped 'thujones' entry and for isoartemesia ketone was not verified in this pass, so those CAS values are left null.
No directly measured public volatility-rate or tenacity-hour figures were verified in this pass.
