Cannabigerolic Acid (CBGA)

Cannabigerolic Acid (CBGA) is a minor cannabinoid found in the cannabis plant. CBGA is the acidic form of Cannabigerol (CBG). CBGA is the starting cannabinoid for three major cannabinoids -- THCA (tetrahydrocannabinolic acid), CBDA (cannabidiolic acid), and CBCA (cannabichromenic acid). CBGA can convert into THC, CBC, CBG, and CBD when it matures. 

Cannabigerolic Acid (CBGA) is a non-psychoactive cannabinoid, meaning that it does not produce a high when smoked or consumed. Other non-psychoactive cannabinoids include: CBC, CBD, CBDV, and CBG.

CBGA and CBG have similar names, but not so much similar properties. CBGA is acidic and a grandparent cannabinoid, while CBG is non-acidic and is actually made from decarbalized CBGA. 

Although CBGA is the grandparent cannabinoid for major cannabinoids, it is lacking major research. The research that has been done though, concludes that Cannabigerolic Acid (CBGA) may help with cardiovascular and metabolic disorders, and even cancer.

There has been much more research done on the decarbed CBGA cannabinoids. Cannabigerol (CBG) research shows that CBG can help fight against inflammation, nausea, and pain. Cannabichromene (CBC) research shows that it may play a role in fighting cancer and tumors. The last cannabinoid that comes from the precursor CBGA is Tetrahydrocannabinol (THC). THC is most commonly known from research regarding its ability to produce a high, or a euphoric feeling. THC promotes relaxation, pain relief, and elation. 

It is very hard to find a cannabis strain with high CBGA because CBGA immediately converts to THCA or CBDA when hit with heat. So, in order to consume concentrated CBGA, it must be consumed in its raw form so that decarbalization does not happen.
