Anti-allergic effect of apple polyphenol on patients with atopic dermatitis: A pilot study

Abstract

The aim of the present study was to evaluate the anti-allergic effect of apple condensed tannins (ACT) in patients with atopic dermatitis (AD) as a pilot study. An ACT supplement given to the patients at oral doses of 10 mg/kg per day for 8 weeks reduced the inflammation, lichenification, cracking, itching, sleep dis- turbance and peripheral blood eosinophil counts. Itching and sleep disturbance scores after ACT supplement even for 2 weeks were significantly decreased compared with the control group. The results suggest that ACT has an anti-allergic effect and that its use improved the symptoms of AD.
