Biosynthesis of cannabigerol

Cannabigerol is normally a minor constituent of cannabis. During plant growth, most of the cannabigerol is converted into other cannabinoids, primarily tetrahydrocannabinol (THC) or cannabidiol (CBD), leaving about 1% cannabigerol in the plant. Some strains, however, produce larger amounts of cannabigerol and cannabigerolic acid, while having low quantities of other cannabinoids, like THC and CBD.

Although cannabigerol is sold as a dietary supplement, its effects and safety for human consumption are undefined.
