Cannabigerol (CBG) is a non-psychoactive phytocannabinode identified in 1964 along with THC and CBD but was isolated a few years later in order to initiate the first thorough investigations. Cannabigerol is found almost exclusively in cannabis plants but its presence in helicrisos has also been documented, especially in Helichrysum Umbraculigerum. It should be remembered that CBG is the neutral form of cannabigerolic acid (CBGA), a biosynthetic precursor from which many other phytocannabinoids are derived. Like these, CBG is a hydrophobic lipid and occurs naturally in the plant after decarboxylation of CBGA.

Cannabigerol is found in higher concentrations in industrial hemp varieties, however its presence is lower in marijuana, up to a maximum of 10% in certain commercial varieties, since it is eventually transformed into a greater proportion in other phytocannabinoids during the process of flowering.
Recent studies and genetic work have achieved plants with enzymes that express almost all of their final content of phytocannabinoids in the form of CBG. To delve into this question may imply the appearance of varieties with controlled cannabinoid profiles, making it easier to obtain them and making their study cheaper.
