The Endocannabinoid System, or ECS for short, is a collection of cell receptors found within mammals. This receptor system exists in the immune system, central nervous system, and in many organs. The primary function of the ECS is to support homeostasis, or the body’s ability to maintain internal balance. The ECS has been shown to support many of the body’s biological tasks including energy and balance, immune function, sleep, memory, metabolism, and the function of the autonomic nervous system.
