Constituent · Sesquiterpene hydrocarbon
β-bourbonene
β-bourbonene is a sesquiterpene hydrocarbon — a heavier, woody or spicy base-note compound that lingers longer than the light terpenes. Across our dataset it was measured in 27 oils (161 samples), concentrating most in Hyssop, Clary sage, Spearmint.
