In simple terms, the Endocannabinoid System (ECS) is the master controller of the body. The ECS is perhaps the most important physiological system involved in establishing and maintaining human health.
The ECS is involved in a variety of human physiological processes including appetite, pain-sensation, mood, memory, and maintaining balance in the body; this is known as homeostasis. Cannabinoids are involved in the fundamental life, death and differentiation alternatives of cells.
Cannabinoid receptors are present throughout the body, embedded in cell membranes. In simple terms, you might say the human organism is extremely cannabinoid-friendly.
There are two primary cannabinoid receptors, CB1 and CB2. These receptors are primarily found in the nervous system and in the organs.
