CBD oil is intended to be taken as a dietary supplement. When used, it has been shown to have a positive impact on the body’s endocannabinoid system (ECS), which is a system of receptors found in the brain and all through the body via the nervous system. The ECS is a key factor in the process of homeostasis, which is in charge of keeping our body in balance by regulating our hunger levels, pain levels, mood, memory, immune system functions, and more.
