Terpenes are considered the main building blocks of any herbal oil, and are largely responsible for the color, smell, and taste. It’s well known that terpenes enhance the effects of CBD, and all of these elements combined create what is known as the entourage effect.
Terpenes aren't just good smelling compounds. They're also known to enhance the therapeutic effects of other cannabinoids, such as CBD. The combination of terpenes and cannabinoids produces a different or greater effect than just the individual effects of cannabinoids or terpenes.
