Korean red ginseng water extract decreased the mRNA expression levels of interleukin-6 (IL-6), thymic stromal lymphopoietin (TSLP), and TNF-α in the 1-chloro-2,4-dinitrobenzene- (DNCB-) induced BALB/c mouse model which develops atopic dermatitis- (AD-) like lesions and alleviates AD-like inflammatory responses [33].
