Yu Cang Powder alleviates allergic rhinitis  by  reshaping gut microbiota
As an important regulator of immune homeostasis, the gut microbiota and its metabolites can influence immune responses in distal organs via the circulatory system. Therefore, we selected the high-dose group of YCP with significant therapeutic effect and analyzed its effect on the gut microbiota structure of AR model mice through the 16S rRNA sequencing. Fecal samples were collected from mice in each group.
