Abstract:Pulmonary fibrosis (PF) is a severe disease, and is one of the hot research subjects. Supplementing qi to remove stasis and phlegm is an important clinical method for treating PF in traditional Chinese medicine. Supplementing qi plays an essential role in this method. This paper reviews the research status of treating PF with astragalus, which is helpful for further exploring the anti-fibrotic mechanism of astragalus and directing its clinical application.
