Terpenes

Secreted in the same glands that produce cannabinoids like THC and CBD, terpenes are aromatic oils that color cannabis varieties with distinctive flavors like citrus, berry, mint, and pine.
There are over 100 Terpenes in the Cannibis, and have been found to be essential building blocks of complex plant hormones and molecules, pigments, sterols and even cannabinoids. Most notably, terpenes are responsible for the pleasant, or not so pleasant, aromas of cannabis and the physiological effects associated with them.
