(SSP) using alcohol and water extraction and investigate whether they can be delivered orally to treat atopic dermatitis (AD). <jats:italic>In vivo<\/jats:italic> investigations demonstrated that SSP notably improved inflammation in mice, reducing ear swelling, scratching frequency, mast cell infiltration, and epidermal thickness. Furthermore, it lowered the levels of associated inflammatory markers, increased the production of skin barrier-associated proteins, and restored gut microbial diversity, which altered the composition of bacterial communities. <jats:italic>In vitro<\/jats:italic> experiments demonstrated that SSP could diminish the levels of inflammatory factors in the human immortal keratinocyte line (HaCaT) and suppress the MAPK\/NF-\u03baB signaling pathway. Our results suggest SSP exerts anti-AD effects and regulates the gut\u2013skin axis in mice. The anti-inflammatory mechanism involves the MAPK\/NF-\u03baB signaling pathway.
