Objective This study aimed to confirm the effect of Sabaek-san extract on the recovery of skin damage in atopic dermatitis-induced mice. Methods In this study, we used 4-week-old NC/Nga mice that were assigned to four groups: control (Ctrl), lipid barrier elimination (LBEG), dexamethasone (Dx) administration after lipid barrier elimination (DxAG), and Sabaek-san extract administration after lipid barrier elimination (SBAG). Ten rats were assigned to each treatment group. After drug administration for 3 days following lipid barrier elimination, ceramide kinase, caspase 14, sodium hydrogen antiporter (NHE), cathelicidin, claudin, and Toll-like receptor (TLR2) were observed to confirm restoration of skin moisturizer production, antimicrobial barriers, and tight junctions in the skin barrier. Results Ceramide kinase and caspase 14 positive reactions were significantly higher in the SBAG group than in the LBEG or DxAG groups. NHE and cathelicidin showed a higher positive reaction in the SBAG group than in the LBEG and DxAG groups. Claudins and TLR2 showed a higher positive reaction in the SBAG group than in the LBEG or DxAG groups. Conclusion It was confirmed that Sabaek-san extract may have the potential to restore damaged skin barrier in atopic dermatitis.
