What does the evidence show for CBG and neuroinflammation?
In a laboratory (in vitro) cell model of neuroinflammation, CBG pre-treatment reduced markers of nerve-cell death, inflammation, and oxidative stress. This is a single test-tube study — not tested in animals or people for this use, and not evidence of benefit in humans.
The grade weighs the claim as a whole, across every study our registry holds on the question. How good any one of those papers is remains a separate matter, and you can judge each on its own terms.
