East Asian herbal treatments have gained attention for their potential benefits in managing COPD. This study aimed to evaluate the inhibitory effects of Gyeongok-go (GOG) on lung injury in a COPD mouse model. Methods: Lipopolysaccharide (LPS)-induced alveolar macrophage (MH-S) cells were treated with GOG (50, 100, 200, and 400 \u03bcg\/mL), and analyzed using enzyme-linked immunosorbent assay (ELISA). C57BL\/6 mice were challenged with cigarette smoke extract and LPS and then treated with vehicle only, dexamethasone (3 mg\/kg), or GOG (100, 200, or 400 mg\/kg). Bronchoalveolar lavage fluid (BALF) or lung tissues were analyzed using cytospin, ELISA, real-time PCR, flow cytometry, hematoxylin and eosin, and Masson\u2019s trichrome staining. Results: Treatment with GOG decreased tumor necrosis factor-alpha (TNF-\u03b1) and interleukin (IL)-6 expression in LPS-challenged MH-S cells. In COPD mice, GOG significantly decreased the elevated numbers of neutrophils, total cells, macrophages, and Gr-1+\/Siglec-F, Gr-1+\/CD11b+, and CD44high\/CD62L\u2212 cells. It also downregulated the expression of TNF-\u03b1, IL-17A, macrophage inflammatory protein-2 (MIP2), and CXC chemokine ligand-1 in BALF. GOG also inhibited the increase in Mip2, Cox-2, and Trpv1 mRNA expression. Moreover, GOG prevented the increase in the number of total cells, neutrophils, Gr-1+\/Siglec-F, Gr-1+\/CD11b+, CD44high\/CD62L\u2212, and CD21+\/CD35+\/B220+ cells in lung tissues. Notably, GOG decreased the severity of lung injury. Conclusions: Overall, these findings indicate that GOG alleviates lung injury, suggesting its potential in the treatment of COPD.<\/jats:p>","DOI":"10.3390\/ph19040618","type":"journal-article","created":{"date-parts":[[2026,4,14]],"date-time":"2026-04-14T10:29:08Z","timestamp":1776162548000},"page":"618","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Inhibitory Effects of Gyeongok-go on Lung Injury in a Chronic Obstructive Pulmonary Disease Mouse Model"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4493-9787","authenticated-orcid":false,"given":"Won-Kyung","family":"Yang","sequence":"first","affiliation":[{"name":"Institute of Traditional Medicine and Bioscience, Daejeon University, Daejeon 34520, Republic of Korea"},{"name":"Division of Respiratory Medicine, Department of Internal Medicine, College of Korean Medicine, Daejeon University, Daejeon 34520, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jin Kwan","family":"Choi","sequence":"additional","affiliation":[{"name":"Division of Respiratory Medicine, Department of Internal Medicine, College of Korean Medicine, Daejeon University, Daejeon 34520, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4598-1733","authenticated-orcid":false,"given":"Seung-Hyung","family":"Kim","sequence":"additional","affiliation":[{"name":"Institute of Traditional Medicine and Bioscience, Daejeon University, Daejeon 34520, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2473-8686","authenticated-orcid":false,"given":"Su Won","family":"Lee","sequence":"additional","affiliation":[{"name":"Division of Respiratory Medicine, Department of Internal Medicine, College of Korean Medicine, Daejeon University, Daejeon 34520, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9823-0618","authenticated-orcid":false,"given":"Yee Ran","family":"Lyu","sequence":"additional","affiliation":[{"name":"KM Science Research Division, Korea Institute of Oriental Medicine, Daejeon 34054, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5645-869X","authenticated-orcid":false,"given":"Yang-Chun","family":"Park","sequence":"additional","affiliation":[{"name":"Institute of Traditional Medicine and Bioscience, Daejeon University, Daejeon 34520, Republic of Korea"},{"name":"Division of Respiratory Medicine, Department of Internal Medicine, College of Korean Medicine, Daejeon University, Daejeon 34520, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,4,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"261","DOI":"10.4046\/trd.2018.0029","article-title":"Committee of the Korean COPD Guideline.
