The worldwide prevalence and severity of allergic diseases including atopic dermatitis and asthma has increased dramatically over the past decade, especially in developed countries. Mast cells are important effector cells in allergic reactions. The purpose of this study was undertaken to investigate the anti-allergic activities of the extract of Duchesnea chrysantha (DCE). DCE was prepared by extracting with 80% ethanol. In the present study, we investigate the effect of DCE on the production of tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6, IL-8, and histamine in the human mast cell line (HMC-1 cells) and on the scratching behavior in hairless mice. Various concentrations of DCE were treated before the activation of HMC-1 cells with phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187. PMA plus A23187 significantly increased TNF-α, IL-1β, IL-6, and IL-8 production compared with media control. We also show that the increased cytokines such as TNF-α IL-1β, IL-6, and IL-8 were significantly inhibited by DCE in a dose-dependent manner. Moreover, DCE inhibited the histamine release from HMC-1 cells stimulated by compound 48/80, which promotes histamine release. Futhermore, the administration of DCE reduced the scratching behavior induced by pruritogen (compound 48/80 or histamine) in hairless mice. These results suggest that DCE has a potential use as a medicinal plant for treatment against allergy-related disease.
