Fenchol

Fenchol, also called 2-fenchanol and fenchyl alcohol, is a minor terpene and an isomer of borneol that is produced by aster flowers, basil, cannabis, eucalyptus leaves, nutmeg, and wild celery (among other plant species).

Within the cannabis genome, fenchol, a somewhat rare terpene, delivers an earthy, piney aroma that may include undertones of lemon and camphor. Fenchol is a primary aroma element of basil and is principally responsible for the herb’s distinctive aroma.

Fenchol is a monoterpene, meaning that it is considerably smaller and less complex than other types of terpenes.
