Objective : In the present study, we investigated the pharmacological profile of the aqueous extract of $Patrinia$ $scabiosaefolia$ Fischer ex Link (EPS) and $Patrinia$ $villosa$ Jussieu (EPV) for its anti-asthmatic activities. The purpose of this study is to ascertain if EPS result in better anti-asthmatic activities and functional outcome as compared with EPV. Methods : In this study, BALB/c mice were systemically sensitized to ovalbumin (OVA) followed intratracheally, intraperitoneally, and by aerosol allergen challenges. We investigated the effect of EPS, EPV on the recruitment of pulmonary inflammatory cells, various immune cell phenotypes, Th1/Th2 cytokine gene expression and production and histamine production in serum. Results : In BALB/c mice, we found that EPV-treated groups had more effectively suppressed inflammatory cell infiltration of lung and BALF, B220+IgE+, CD11b+Gr-1+ cell population in lung and these occurred by suppressing the gene expression of IL-4, IL-5 and IL-4 cytokine production in BALF and serum. Conclusions : These results suggest that EPV may play an important role in the control of anti-asthmatic activities by down-regulation of Th2 cytokine (especially IL-4, IL-5). In general, EPV has shown a better anti-asthmatic activities compared to EPS.
