Consider a conductor of an orchestra, the conductor serves as a messenger to composers and keeps the pace of the music. The ECS serves a similar role within our body as it functions to keep other major systems i.e. central nervous system, digestive system, and immune system balanced through internal cannabinoid receptors. The cannabinoid receptors (CB1 and CB2) regulate important functions such as digestion, inflammation, mood, sleep, pain, and immune function. The primary function of our ECS is to promote homeostasis – the tendency of organisms to auto-regulate and maintain a stable, balanced environment.
