About this composition

Sweet fennel oil is the anethole-rich var. dulce type with markedly lower fenchone than bitter fennel. The record below combines EMA's var. dulce definition with a directly readable commercial sweet-fennel technical profile whose constituent ranges match the sweet anethole chemotype.

What we're still learning · 4 data gaps

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

  • Odor intensity 60 is a normalization of the cited medium-strong aroma band into the archive's 0-100 scale.
  • pct_typical values for the constituents with min/max ranges are midpoint derivations from the cited ranges because the readable sources did not publish a single dominant-chemotype average.
  • No direct public volatility-rate or tenacity-hour values were located for sweet fennel essential oil.
  • cis-anethole is published only as a maximum value in the reviewed sources, so pct_typical remains null.
