Eucalyptol
Eucalyptol, also known as Cineol, is the terpene responsible for the pleasurable and cooling scents found within eucalyptus, mint, rosemary, tea tree, mugwort, bay leaves, sweet basil, sage, and some strains of cannabis. When smoked, one can experience a sweet, refreshing cooling taste.
Understanding Terpenes
Terpenes are aromatic molecules produced from the resin of plants. Along with flavonoids, terpenes are the scents/smells that we associate with plants. Different cultivars of Cannabis have their own combinations of terpenes which causes each strain to have their own unique scent. Conversely, cannabinoids do not produce scents.
