What Are Terpenes?

Terpenes are ​ aromatic organic compounds ​ concentrated in unfertilized female flowers that are responsible for the odor, color, and flavor of cannabis. They’re part of a plant’s defense mechanism, working to repel insects and grazing animals while attractinghelpful predators and pollinators​ . Terpenes are biologically active, meaning they affect animal and human behavior even when they are inhaled in small amounts. Cannabinoids like CBD work synergistically with terpenes to enhance the therapeutic benefits of CBD. Over 15,000 terpenes have been identified in nature, with 200 primary and secondary terpenes described in cannabis.

The Entourage Effect

Coined in 1998 by cannabis researcher Dr. Raphael Mechoulam — who is considered to be the godfather of cannabis research — the entourage effect is used to describe how cannabinoids like CBD work synergistically with terpenes to enhance the beneficial effects of cannabis in the human body. The entourage effect explains why broad spectrum cannabis products that contain cannabinoids and terpenes are more effective than CBD on its own.
