The mechanism of immune imbalance plays a dominant role in the pathogenesis of asthma. It is believed that the imbalance of Th1/Th2 ratio is the main immune pathogenesis of asthma. However, in recent years, The research on the relationship between Th17/Treg immune imbalance and asthma has been increasing, and a large number of experiments and clinical Studies have shown that the up-regulation of Th17 cell ratio and the decrease in the proportion of Treg cells lead to a imbalance in Th17/Treg that is closely related to the onset and severity of asthma. Traditional Chinese medicine has a long history of treating asthma. The use of modern science and technology to explain the mechanism of TCM treatment of asthma is a hot topic at present. It not only gives scientific meaning to TCM treatment of asthma, but also brings good news to more asthma patients. In this paper, by expounding the role of Th17 and Treg cells in asthma, the research progress of the influence of traditional Chinese medicine on the balance of asthma Th17/Treg in the past decade is reviewed for peer review.
