About this composition

This Oregon Roman chamomile record uses the EMA assessment report as the open quantitative anchor for the classic ester-rich Roman chamomile profile, then ties the archive entry to Oregon-grown material through live supplier pages from Eden Botanicals and Nature Packaged. Those origin-specific pages support the Willamette Valley / Oregon provenance, flower distillation, fruity-herbaceous apple-like odor profile, and a public 5% special dilution rate for topical use.

What we're still learning · 3 data gaps

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

max_dermal_pct 5 is taken from a live Oregon supplier's published special dilution rate rather than a public primary safety monograph.
Odor intensity 80 normalizes Eden Botanicals' qualitative 'powerfully diffusive' and 'strong odor intensity' wording into the archive's 0-100 scale.
No public Oregon lot-specific GC-MS or COA was found in this pass, so the constituent percentages remain EMA-backed Roman chamomile values rather than Oregon-batch analytics.
