Cannabinoids are naturally produced by the industrial hemp plant and the human body. Since cannabidiol, produced by the industrial hemp plant, is considered a "phytocannabinoid". The prefix "phyto" means that it is plant based. Cannabinoids that are produced by the human body are considered “endocannabinoids". The human body has a system called the "endocannabinoid system" which has receptors that allow cannabinoids to bind to them and promote wellness.
