Abstract

The prevalence of type I allergies, including food allergies and atopic dermatitis is increasing worldwide. Chinese medicines and crude drugs have been used for treatment of these allergies ; however, the mechanisms of the treatment efects remain unclear. In the present study, we investigated the inhibitory efects of crude drugs on the degranulation of mast cells using the crude hot-water extracts of 83 types of crude drugs. Among the crude drugs, extracts from Ni-kei, fun-bo-i, ku-se-ki and on-ji most significantly inhibited the release of b-hexosaminidase in RBL-2H3 cells, with IC50 values of 215.7, 79.1, 187.6 and 288.1 ug/ml, respectively.
