Leaf Oils
'Leaf oils' is a non-specific umbrella term. Many specific leaf-derived essential oils are GRAS as flavorings (e.g., bay, peppermint, spearmint), but identity matters: certain leaf oils (e.g., pennyroyal, sassafras) are toxic.
What it is
Generic umbrella term for essential oils extracted from plant leaves (e.g., bay, eucalyptus, mint).
Flavoring/aromatic component.
Why it's flagged
- Some leaf essential oils (e.g., pennyroyal, sassafras) are toxic and not GRAS
What regulators actually say
"Section 182.20 lists essential oils, oleoresins (solvent-free), and natural extractives GRAS for their intended use."
