Just like our other physiological systems in the body (skeletal, muscular, cardiovascular, etc.), the body has an extra one known as the ECS. This system is a sort of communication system built up of receptors and endocannabinoids that communicate with each other and other systems of the body including that of the immune, reproductive, cardiovascular, respiratory, digestive, nervous, endocrine, and musculoskeletal systems. It has evolved over millions of years and is part of all animals including humans. The ECS is the reason why CBD is able to interact with our bodies. We all produce our own endocannabinoids, so surely enough, there’s a system that is there to process those endocannabinoids.
