Terpenes are aromatic oils. They are secreted in the same glands producing cannabinoids like THC, and the reason that your favorite cannabis varieties end up distinctive flavors like citrus, berry, mint, and pine. Some terpenes might promote relaxation and stress-relief, while others can boost focus and understanding. Myrcene, for example, can be found in relaxing cannabis strains like Blue Dream and Granddaddy Purple. Terpinolene is commonly found in uplifting, active strains like Jack Herer and Ghost Train Haze.
The effect profile of any given terpene can change in other compounds in a phenomenon known as the entourage effect. Further research is needed to understand each terpene’s impact when used in harmony with others. They may also add therapeutic value to cannabis, based on their unique medicinal properties.
