About this composition
This record combines the EMA/European Pharmacopoeia identity envelope for cineole-rich eucalyptus oils with a public 2025 Blue Mallee batch profile published by Perfect Potion. Eucalyptus polybractea is one of the classic high-cineole mallee species, and the reviewed sources consistently describe it as a strongly cineolic oil with only small amounts of monoterpene side constituents.

What we're still learning · 2 data gaps
Good decisions start with knowing what is — and isn't — in the evidence.
- No directly measured public volatility-rate or tenacity-hour data were verified in this pass.
- The stored odor_intensity 80 is an archive normalization of public 'strong' aroma language, not a native published 0-100 measurement.
