Black Walnut for Skin Health

Research on Black Walnut for skin health is essentially nonexistent in the available evidence base. The single linked study is a population health surveillance program — the Survey of the Health of Wisconsin — that tracks a broad range of health and environmental factors across Wisconsin adults and children, but does not specifically investigate Black Walnut or its effects on skin. No clinical trials, observational studies, or mechanistic research examining Black Walnut for skin health outcomes were identified in this review. As a result, no meaningful conclusions can be drawn about whether Black Walnut offers any benefit, harm, or neutral effect for skin health based on the current evidence.
