The endocannabinoid system (ECS) refers to a collection of cell receptors and corresponding molecules that regulates processes such as sleep, mood, appetite, memory, and fertility. This was discovered in 1992 by researchers trying to discover how cannabis interacts with mammals. The scientists came across an unknown molecular signaling system within the body that is involved in regulating a broad range of biological functions.
This system was named the endocannabinoid system (ECS). It was later discovered that the ECS is present in all vertebrates—mammals, bird, reptiles, amphibians, fish, etc, – they all produce endocannabinoids!
The ECS performs multiple tasks, but the goal is always to maintain a stable environment despite fluctuations in the external environment. It is the system that creates homeostasis or balance within the body.
