The claim
Posts online say that CBD (cannabidiol) helps with atopic dermatitis (eczema).
Where research stands
We found 13 published papers on CBD (cannabidiol) and atopic dermatitis (eczema). They were published between 2019 and 2026. 2 of them are studies in people. 2 of them compared people who got it with a group that did not. 4 were studies in animals, and 2 were only in cells in the lab. 1 paper is a review that sums up other studies. 1 new study in people is running or will start soon, say the trial registers.

Verdict
CBD (cannabidiol) has been tested in randomised trials in people with atopic dermatitis (eczema).
What this means for you: A study in people is not proof that it helps you. Do not stop or change your medicines because of it. Ask your doctor before you start taking it.
