Abstract:Objective:To study the anti-allergic reaction of‘Yajiebasha'.Methods:The allergic reaction of‘Yajieshaba'was measured by passive cutaneous anaphylaxis(PCA),histamine-induced itch,and DNCB-induced delayed type hypersensitivity(DTH)in mice,respectively.Results:‘Yajieshaba'showed a significant inhibition on PCA and histamine-induced itch,it also inhibited DNCB-induced DTH in mice.Conclusions:These results indicate that‘Yajieshaba'has the inhibition of type Ⅰ and type Ⅳ allergic reaction.
