Cannabidiol (CBD) is one of more than 100 known phytocannabinoids and is predominant in Cannabis sativa L. hemp varieties, comprising between 15-70% of the plant’s raw extract. One of the most common non-psychoactive cannabinoids in the cannabis plant, CBD occurs in the largest concentrations after THC and THCa.
While THC’s psychoactive effects result from it binding to the CB1 receptor, it’s thought that CBD has no binding affinity to either the CB1 or CB2 receptors. Instead, the benefits of CBD come from its ability to modulate ion channels in the body, along with several non-cannabinoid receptors.
In short, CBD promotes the body’s use of its own cannabinoids.
