Outline
Asthma is a chronic inflammatory disease involving eosinophils, mast cells, lymphocytes, neutrophils and other inflammatory cells and immune components. Chinese medicine has unique advantages in the treatment of asthma. In this study an ovalbumin (OVA)-induced asthma model in rats was used to verify the effect of the total sesquiterpenoids of Flos Farfarae (F.F.S) on asthma. The results show that the F.F.S has anti-asthmatic effects. Metabolomic analysis showed that 25 metabolites were changed in asthmatic rats, and 18 of them could be attributed to F.F.S. F.F.S. can block the over-activation of p65 NF-κB, preventing the transmission of pro-inflammatory factor signals to cells. F.F.S. thus could reduce the over-activation of inflammatory cells, inhibiting the secretion of inflammatory factors and further alleviating asthma inflammation. This study lays a foundation for further new drug research. The mechanism of F.F.S. on asthma needs further investigation.
