The endocannabinoid system is a biochemical communication system in our bodies that helps regulate everything from nerve function and muscle coordination to immunity and blood circulation. It’s made up of two types of cannabinoid receptors, CB1 and CB2, which both promote neural sensitivity and efficacy. CB1 receptors are found in the brain and central nervous system and influence our emotions, mood, appetite, coordination, movement, and pain. CB2 receptors are found primarily in the immune system, but also in peripheral organs and tissues of the muscular and cardiovascular systems.
While our body naturally produces endocannabinoid compounds that react with the CB1 and CB2 receptors and help keep the body balanced, when we experience injury, disease or other deficiency of endocannabinoids, the compounds found in CBD, called phytocannabinoids, can help pick up the slack. But instead of interacting directly with CB1 and CB2 receptors like THC compounds, CBD compounds simply help to stimulate the receptors and get the body to recognize and use more of its natural cannabinoids and neurotransmitters. (Hence, no “high”.)
