In the last twenty years, modern science has discovered a natural “receptor” phenomenon in the human body — the Endo-Cannabinoid System — which scientists say may play a crucial role regulating our physiology, mood and everyday experience. The discovery of these receptors in the brain and immune system that respond to stimuli from cannabis, and the subsequent identification of molecules in our own bodies that bind to these receptors (endocannabinoids) – may have significantly advanced our understanding of human biology, health and disease.
There are two types of cannabinoid receptors in humans: CB1 and CB2. CB1 receptors are present in the brain and spinal cord and in certain peripheral tissues, while CB2 receptors are found primarily in the immune system.
Some scientists think CBD may be — in addition to its binding with the CB1 receptors — the main non-psychoactive cannabinoid that binds the receptors in your immune system, thus possibly providing a variety of medicinal benefits.
