Nakai (SCN) is a medicinal plant commonly used against inflammation. However, the underlined mechanisms against skin inflammation is poorly understood. The present study investigated the effects of SCN leave extract on ear inflammation. To this aim, six-week-old male ICR mice was subjected to 12-O-tetradecanoyl-phorbol-13-acetate induce ear edema, which were then topically treated with the leave extract of SCN. Ear thickness, weight, and morphological changes were recorded to ensure the induction of ear edema. Further, histological analysis and protein expression for inflammatory markers were also recorded to validate the study. Topical treatment with SCN repressed TPA-induced ear edema in a dose-dependent manner. Further, SCN treatment significantly antagonized the protein expression of MAP kinase signaling pathway and reduced the effect of TPA-induced NF-κB activation, sequentially, deactivated its transcriptional targets in a dose-dependent manner. Collectively, the study suggested that SCN could be a useful therapeutic agent against skin inflammation.
