CBG is short for Cannabigerol, which is a form of cannabigerolic acid (CBGA). CBG has been uniquely connected to potential digestive benefits and potential antimicrobial qualities in cannabis research.
CBN is actually more closely related to THC than it is to CBD in terms of chemical composition. Yet, CBN does not significantly stimulate the brain’s CB1 and CB2 receptors (so it does not have intoxicating qualities). Early research and anecdotal evidence suggests that CBN aids sleep.
