An intraocular-pressure effect is sometimes attributed to CBG, but the mechanism is unclear and the data are sparse and conflicting.
The question is still open: our registry holds a primary study neither for the claim nor against it. Open is a different place from tested-and-failed, and every bit as far from shown-to-work.
The CBG monograph covers the compound end to end, and the gap-map charts the questions nobody has tested yet.
CBG acts on α2-adrenoceptors, which help regulate blood pressure; anyone taking cardiovascular medication should consult a clinician before using CBG products. Nothing on this page is medical advice, and no statement here is a claim that CBG treats, cures, or prevents any condition. Grades are based on the studies we had checked as of 9 August 2026.
