Phytocannabinoids are naturally occurring chemical compounds found in the cannabis plant. They are a broad class of chemical defined by their effects on cannabinoid receptors, rather than by structure. These compounds are unique to cannabis and are responsible for many of the characteristic effects of cannabis. The major cannabinoids found in cannabis flower are cannabidiol (CBD) and tetrahydrocannabinol (THC). Phytocannabinoids interact with the endocannabinoid system in the human body, which plays a crucial role in regulating various physiological processes such as appetite, pain sensation, mood, and memory.
