Phytocannabinoids are compounds naturally present in specific species of plants including hemp. In hemp plants, phytocannabinoids are most concentrated in structures called trichromes, naturally occurring resin glands found on the surface of plants. When cannabinoids are derived from plants, they are named phytocannabinoids, as the prefix ‘phyto’ is used when something is related to plants. Importantly, cannabinoids are also produced by mammals, in which case they’re called endocannabinoids – endo is from endogenous, meaning from within. All cannabinoids interact with the body’s endocannabinoid system. To learn more about cannabinoids, visit our FAQs.
