Thermal-extraction context
Reported biological activity
Human evidence
No verified controlled human study of inhaled isolated fenchol was identified for this archive [^2].
Animal or laboratory evidence
In vitro screens report TRPA1 antagonism and FFAR2 (GPR43) agonism at micromolar concentrations, plus antimicrobial and antioxidant activity in essential-oil or cell-free assays; none establish effects at cannabis-relevant inhaled exposure 1.
Traditional or anecdotal claims
Used in traditional preparations of fennel and basil for digestive and respiratory use.
Cannabis laboratory results
Reported at 0.028–1.09 mg/g dry weight in dried flower across chemotypes I–III in a pooled literature survey 2. Consult Lab Results for batch-level measurements.
