Cannabinoids are a diverse class of chemical compounds that occur naturally in the human body (endocannabinoids) and cannabis plants (phytocannabinoids), and interactions with the endocannabinoid system (ECS) trigger various physiological actions. Among the 500 or so natural components in cannabis, more than 100 are classified as phytocannabinoids. Cannabidiol (CBD) appears to play the most significant role in the plant’s medicinal benefits.
