Full spectrum CBD oil, such as that used in M CBD products, contains a variety of cannabinoids and terpenes as well as other beneficial compounds. Each of the compounds has particular effects on the human body. Because terpenes can affect how the body responds to cannabinoids, the combined effect is often greater than the sum of the individual effects. The overall effect produced is known as the entourage effect. Non-full spectrum products do not have the benefit of the entourage effect and are therefore not recommended.
