Abstract excerpt

CBDA, the acidic precursor of CBD, was investigated in preclinical models of vomiting (Suncus murinus) and nausea-induced conditioned gaping (rats). CBDA was substantially more potent than CBD on a per-mg basis at suppressing both phenomena, mediated through enhanced 5-HT1A receptor activation. The findings are consistent with growing evidence that CBDA has its own pharmacology distinct from its decarboxylated form CBD, particularly at serotonergic targets.

How to read this paper

Foundational CBDA paper. Read alongside Pellesi 2018 (oral pharmacokinetics) for the full picture of why the acidic form matters at the molecular level. Most CBD products on shelves today contain mostly decarboxylated CBD — extraction-side decisions can shift that.
