In mice with IgE/OVA-induced asthma, oral administration of catalpol remarkably suppressed the production of OVA-specific IgE, the development of airway hyperresponsiveness (AHR), and the infiltration of eosinophils and neutrophils into the lungs. Histological studies demonstrated that catalpol substantially inhibited the recruitment of mast cells and increased mucus production in lung tissues. Catalpol-treated mice had significantly lower levels of helper T cell type 2 (Th2) cytokines (IL-4, IL-5, and IL-13), PGD2, eotaxin-1, an
