When a person consumes CBD, it interacts with certain receptors in the body. These receptors are called the Endocannabinoid System (ECS). They are located throughout the entire body and signal the pathways for how the body responds to stimuli. The ECS helps regulate many things including, brain function, mood, immune response, sleep, inflammation, stress, and pain. CBD has been shown to act on and stimulate these ECS receptors and serotonin pathways in the brain.
