(Natural News) There is a system within the human body that regulates pain and modulates the immune system. This little-known system of the body is a major gateway for regulating inflammation in the cells. This body system is often left out of human anatomy textbooks. This system is like a door that connects the nervous system with the immune system. This innate portal of healing is called the endocannibinoid system. The key to unlocking this door is found in cannibinoids, which are plant-based or endogenous compounds that bring down inflammation in the cells and communicate healing to the body.
