IL4 and asthma: Gene expression of IL-4 in the group treated with high concentration of the extract (p < 0.05), IL-17 in asthma groups treated with all extract concentrations (p < 0.001 for all cases) and TGF-β in the groups treated with the medium and high extract concentrations (p < 0.001 for both cases) were significantly decreased compared with untreated asthma group (Figures 4D, 5B, 6B).
