To understand how Cannabidiol (CBD) works you must understand the endocannabinoid system (ECS). We all have an endocannabinoid system, as do all mammals, birds, reptiles and fish.
Our bodies produce endocannabinoids to communicate with various parts of the body. Being a phytocannabinoid, CBD is derived from a plant. It can affect our bodies in the same way and endocannabinoids.
Our bodies need cannabinoids as part of its healthy functioning, so like taking vitamins and other supplements for your health, adding CBD can become an essential part of having optimum mind and body wellness.
Wikipedia describes the endocannabinoid system. “The endocannabinoid system (ECS) is a biological system composed of endocannabinoids which are endogenous lipid-based retrograde neurotransmitters that bind to cannabinoid receptors (CBRs). Also, cannabinoid receptor proteins that are expressed throughout the vertebrate central nervous system (including the brain) and peripheral nervous system. The endocannabinoid system remains under preliminary research. It may be involved in regulating physiological and cognitive processes, including fertility, pregnancy, pre- and postnatal development, various activity of immune system, appetite, pain-sensation, mood, and memory, and in mediating the pharmacological effects of cannabis.”
