CBD interacts directly with the endocannabinoid system (ECS) already present in our bodies. Mammals, including both people and pets, have an ECS. This ECS has a number of receptors that help regulate important bodily functions like a neurotransmitter and hormone secretion, temperature, and metabolism, as well as controlling inflammation, to name only a few. CBD essentially benefits the body by acting as a natural booster to the functions that the ECS is performing.
