Endocannabinoids are naturally occurring compounds in the body that interact with the endocannabinoid system, which helps regulate various physiological processes. They are similar in structure to the active compounds found in cannabis, such as THC and CBD, but are produced by the body itself. These molecules play a crucial role in maintaining balance, or homeostasis, by influencing functions like mood, appetite, pain sensation, and immune response. Endocannabinoids are synthesized on demand and bind to cannabinoid receptors to exert their effects, highlighting their importance in overall health and well-being.
