Gentiopicroside Reduces Pain, Pruritus, and Corticosteroid Addictive Dermatitis

Abstract

Corticosteroid addictive dermatitis (CAD) has rapidly emerged as a health problem which is difficult to cure. The dermatitis control is general with the tacrolimus, pimecrolimus, and antihistamines, and these synthetic drugs are likely to have some side effects, and how to use the nonirritating natural product to reduce the CAD has been rarely reported. Strong evidence indicates that gentiopicroside (GPS) has been reported to have anti-inflammation and anticancer properties. In the present study, we invented a device to collect GPS to study the effect of GPS on pain, pruritus, and CAD repair in model animals. Our results showed that the data on antipain and antipruritus treated with GPS were better than those of control group, and the inflammation of rabbit skin upon 2,4-dinitrochlorobenzene exposure reduced by GPS. In conclusion, GPS could be a factor for antipain, antipruritus, and CAD repair; hence, these findings suggest that it can act as a protective factor for CAD.
