To understand how CBD works, you’ll need to dive into a little science. CBD is able to produce medicinal effects because it engages with a unique cell signaling network within the human body. That network is called the endocannabinoid system , and it was named after the cannabis plant. As a cell signaling system, the ECS can be compared to a traffic cop that coordinates movement at a busy intersection. Specifically, the ECS coordinates communication between the central nervous system and the body’s peripheral and visceral organs.
