The Effect of Modified Erchen Decoction on Lung Function and Serum IL-6 and IL-13 Levels in Chronic Obstructive Pulmonary Disease Patients with Lung Phlegm-Turbidity

Key Points

• To compare the effects of modified Erchen Decoction on lung function and serum IL-6 and IL-13 levels in COPD patients with phlegm-turbidity.
• 72 COPD patients were randomly assigned to treatment with modified Erchen Decoction or standard care.
• Lung function (FVC, FEV1, FEV1/FVC) and serum IL-6 and IL-13 levels were measured before and after treatment.
• Clinical symptoms were assessed using traditional Chinese medicine scoring.
• Both groups showed significant improvement in clinical symptom scores (P<0.01).
• FVC, FEV1, and FEV1/FVC increased significantly in the treatment group (P<0.01).
• Serum IL-6 and IL-13 levels decreased significantly in the treatment group (P<0.01).
