Cinnamomum verum extract as a potential therapeutic for atopic dermatitis through reducing lipid peroxidation and oxidative stress

Background: Oxidative stress and lipid peroxidation play crucial roles in the pathogenesis of atopic dermatitis (AD). Among the by-products of lipid peroxidation, 4-hydroxynonenal (4-HNE) is known to exacerbate inflammatory responses. Methods: J. Presl. [Lauraceae] extract (CVE) in mitigating oxidative stress and suppressing 4-HNE-mediated inflammatory pathways in an AD model. The antioxidant properties of CVE were evaluated through lipid peroxidation assays, reactive oxygen species (ROS) measurement, and cytokine profiling. Results: CVE treatment significantly reduced 4-HNE levels, decreased pro-inflammatory cytokine expression, and restored antioxidant enzyme activity. Conclusion: These findings suggest that CVE may serve as a natural therapeutic agent for managing oxidative stress and inflammation in AD.
