Abstract Background Palmijihwanghwan (PJH) is a traditional medicine and eight constituents derived from PJH possess anti-inflammatory activities. However, the scientific evidence for its potential as a therapeutic agent for inflammatory lung disease has not yet been studied. In this study, we examined the protective effect of PJH in a mouse model of chronic obstructive pulmonary disease (COPD) induced by cigarette smoke (CS) with lipopolysaccharide (LPS). Methods Mice received CS exposure for 8 weeks and intranasal instillation of LPS on weeks 1, 3, 5 and 7. PJH (100 and 200 mg/kg) was administrated daily 1 h before CS treatment for the last 4 weeks. Results Compared with CS plus LPS-exposed mice, mice in the PJH-treated group showed significantly decreased inflammatory cells count and reduced inflammatory cytokines including interleukin-1 beta (IL-1β), IL-6 and tumor necrosis factor alpha (TNF-α) levels in broncho-alveolar lavage fluid (BALF) and lung tissue. PJH also suppressed the phosphorylation of nuclear factor kappa B (NF-κB) and extracellular signal-regulated kinase1/2 (ERK1/2) caused by CS plus LPS exposure. Furthermore, CS plus LPS induced increases in matrix metallopeptidase (MMP)-7, MMP-9, and transforming growth factor-β (TGF-β) expression and collagen deposition that were inhibited in PJH-treated mice. Conclusions This study demonstrates that PJH prevents respiratory inflammation and airway remodeling caused by CS with LPS exposure suggesting potential therapy for the treatment of COPD.
