We aimed to evaluate the efficacy and safety of Bu-fei Yi-shen granules (BYGs) for COPD.Patients and Methods: We conducted a multicenter, randomized, double-blinded, placebo-controlled trial of 348 COPD patients with GOLD 3– 4 COPD. The patients were randomly assigned into experimental or control groups in a 1:1 ratio. Patients in the experimental group were prescribed BYG, while those in the control group were administered a placebo, orally, twice daily, with 5 days on and 2 days off per week for 52 weeks. The outcomes included AEs, pulmonary function, clinical signs and symptoms, dyspnea scores (mMRC), quality of life scores, and a 6-minute walk test (6MWT).Results: A total of 280 patients completed the trial, including 135 patients in the experimental group and 145 in the control group. Compared to the control group, significant differences were observed in frequencies of AEs (mean difference: − 0.35; 95% CI: − 0.61, − 0.10; P = 0.006) and AE-related hospitalizations (− 0.18; 95% CI: − 0.36, − 0.01; P = 0.04), 6MWD (40.93 m; 95% CI: 32.03, 49.83; P
