Cannabidiolic acid (CBDa)
CBDa, CBD acid or CBD-a is the main form in wich CBD exists in the raw cannabis plant, together with THCa (THC acid). CBD is obtained by non-enzymatic decarboxylation from the acid form of the cannabinoid, a reaction that occurs when the compounds are heated. Heating or catalysing CBDa converts it into CBD, increasing the overall CBD level. Research shows that higher concentrations of CBDa exhibit more pronounced antimicrobial activity than CBD alone.
