Introduction: Yunvjian (YNJ) decoction, a classic traditional Chinese medicine prescription for inflammatory diseases, has demonstrated good therapeutic effects in the clinical treatment of pneumonia. The aim of this study was to clarify the effective ingredients and mechanism of action of YNJ on lipopolysaccharide (LPS)-induced acute lung injury (ALI).
Methods: The effects of YNJ were evaluated in a mouse model of LPS-induced ALI and in LPS-treated MLE-12 murine lung epithelial cells and RAW264.
