The aim of this study is to explore the potent phosphodiesterase 4 and 7 inhibitor from various herbal medicines for atopy treatment. In this study, 51 kinds of each herbal medicine, which were extracted with ethanol, was carried out the screening of PDE 4 and 7 inhibition using enzyme inhibitory assay. Of these, 8 species of herbal medicines, Rubus coreanus, Duchesnea chrysantha, Alisma orientale, Rehmannia glutinosa, Angelica dahurica, Thuja orientalis, Astragalus membranaceus and Perilla frutescens were screened as potential inhibitor against PDE 4 and 7. Among 8 species, Duchesnea chrysantha showed poteinial anti-atopic effect on DNCB-induced atopic model. Duchesnea chrysantha extract decreased serum IgE and histamine release significantly.
