Cannabigerolic acid (CBGA)
the mother acid: heat turns it into CBG, and enzymes turn it into THCA, CBDA and CBCA.
What are cannabinoid acids?
Cannabinoid acids are what the cannabis plant actually makes. The familiar “neutral” cannabinoids, CBG, CBD and THC among them, turn up in the living plant only in small amounts. They form from the acids when heat drives a carboxyl group (–COOH) off as CO₂, the reaction chemists call decarboxylation, and that chemistry is established.
At the root sits CBGA, the mother acid. Plant enzymes turn cannabigerolic acid into the other acid lines (THCA, CBDA, CBCA), and each of those decarboxylates in turn to its neutral compound.
Why should anyone making a product care? Because gentle heat, roughly 110–160 °C, is enough to drive off the CO₂ and turn an acid into its neutral form, and the difference can be the whole product. Raw THCA is non-intoxicating; decarboxylate it and you have intoxicating THC.

decarboxylates to CBD.
decarboxylates to CBC.
decarboxylates to Δ⁹-THC with heat.
the varin “mother acid”; decarboxylates to CBGV.
decarboxylates to THCV.
decarboxylates to CBDV.
Take any of these acids through the heat and you land among the minor cannabinoids, where the neutral forms have their hub. The three-carbon (varin) acids turn up again under the varin cannabinoids.

Informational only, not medical advice. CBG Atlas is a scientific reference. Nothing here diagnoses, treats, cures or prevents any disease. Every claim on the page carries the grade of the evidence behind it, and the grade sets the words the claim may use. How we grade evidence.
Informational only — not our claims, and not advice. The statements on this page about potential effects, benefits, or uses reflect claims made by third parties (manufacturers, media, traditional use, or preliminary research) and are presented for educational and informational purposes only. CBG Atlas does not make, adopt, endorse, or affirm these claims, and does not represent them as fact. These statements have not been evaluated by the Food and Drug Administration (or any regulator) and are not intended to diagnose, treat, cure, or prevent any disease. Nothing here is medical, legal, or professional advice; cannabinoid effects, safety, and legal status vary by person, product, and jurisdiction and can change over time. Consult a qualified professional before making any health or purchasing decision. Where we can, we show how strong the evidence is and cite the source; where evidence is thin or absent, we say so.

Cardiovascular note. CBG is a potent α2-adrenoceptor agonist in vitro, and α2 agonism can lower blood pressure. Anyone taking blood-pressure or other cardiovascular medication should consult a clinician before use. This is educational information, not medical advice.
