Bufei Recipe to lower COPD risk in high-risk people
Part of Lungs & breathing clinical trials.
This study tests whether a traditional Chinese herbal formula called Bufei Recipe can lower the chance of developing COPD in people who are at high risk. It looks at people who already have some lung symptoms like coughing or shortness of breath, and who have a specific lung function pattern.
Summary written for real people, not researchers, by Clin2.
