Lingganwuweijiangxin Decoction suppresses allergic airway inflammation in Guinea pigs with cough variant asthma by regulating the treg/Th17 balance and the JAK1/STAT6 signaling pathway

LD significantly reduced coughs and airway inflammation in the CVA guinea pig model by regulating TRPA1, TRPV1, SP, regulatory T cell/T helper 17 cell balance, and the JAK1/STAT6 signaling pathway. These effects were comparable to BUD, suggesting that LD may be a viable alternative treatment for CVA.
