Cannabigerol, or CBG, is a non-psychoactive cannabinoid typically most abundant in low-THC. Like THC, CBG reacts with the cannabinoid receptors in the brain. … CBG works to fight inflammation, pain, nausea and works to slow the proliferation of cancer cells.CBG is more effective than CBD for treating migraines and easing muscle soreness. CBD may be better suited for reducing inflammation because it has less psychoactivity than CBG.
