CBD, extracted from industrial hemp, is just one of more than 100 compounds called cannabinoids. The human body has an endocannabinoid system commonly known as ECS. Receptors within the ECS system receive and translate signals from cannabinoids. The human body also produces its own cannabinoids which are called endocannabinoids. They help regulate vital human functions such as immune system responses, sleep, and pain management.
CBD does not directly affect the endocannabinoid system. Instead, it activates or suppresses other compounds in the endocannabinoid system. CBD may stop the body from absorbing anandamide, which is a pain regulating compound. Though not scientifically proven, some believe that increased levels of anandamide in the bloodstream may reduce the perception of pain.
