The endocannabinoid system (ECS) is a regulatory system responsible for maintaining homeostasis – the body’s ability to keep a state of internal balance, enabling all systems and organs to function optimally together. Within the ECS there are receptors known as CB1 and CB2, which can be found in almost all major parts of the body. Endocannabinoids are cannabinoids that the body produces naturally. When endocannabinoids bind to the CB1 and CB2 receptors they allow for two-way communication between cells – when something is out of balance signals are sent to the ECS to help correct it through a wide range of biological functions.
