Joe Rogan on health: what the evidence says · JRE #1213

What the evidence says 01 / RECORD

The claim references a single historical case report published in 1952 in the British Medical Journal by anesthetist Albert A. Mason, describing a teenage boy diagnosed with congenital ichthyosiform erythrodermia of Brocq, a rare hereditary skin disorder, whose skin cleared substantially (nearly complete clearing on some areas, partial elsewhere) over repeated sessions of hypnotic suggestion applied one body region at a time. Mason published a further account in 1955 discussing his continued clinical experience with the case. In the following years, Mason and other clinicians who attempted the same hypnotic approach with additional ichthyosis patients were unable to reproduce comparable results, and no controlled study has since replicated the original finding. The condition treated was a specific, rare subtype rather than ichthyosis in general, and the improvement was not uniform across the whole body as the claim implies. The episode is best characterized as a single, unreplicated historical case report rather than established evidence that hypnosis cures ichthyosis.
