This study was conducted to clarify the effects of the Korean raisin (Hovenia dulcis Thunb) extracts and polyherbal extracts consisted of 6 types herbal extracts including HDT (HDTmix) on $CCl_4$ induced organ damages. Extracts were prepared by autoclave ($121^{\circ}C$, 15 psi, 3 hours) and filtered with nylon cloth and filter paper then freezing dried. Male Sprague-Dawley rats $(200^{\circ}{\ae}20g)$ were used as experimental groups, which were divided into 5 groups; intact control group (100 mg/kg), $CCl_4$ dosing group (100 mg/kg), $CCl_4$ dosing after HDT extract dosing group (100 mg/kg), $CCl_4$ dosing after HDTmix dosing group (100 mg/kg), Silymarin dosing group (5 mg/kg) after all test articles were orally dosed once a day for 28 days. They were sacrifiled under ether anesthesia. HDT extracts and HDTmix dramatically inhibits the $CCl_4$ intoxicated hepato/nephropathies with immuno-suppress changes on the spleen. They showed more dramatical protective effects on most of specific organs compared to that of Silymarin 5 mg/kg except for hepatoprotective effects in which, quite similar effects were detected. In addition, HDT extracts showed synergic effects with other types of herbal extracts because HDTmix showed more favorable protective effects on the all specific organs showing $CCl_4-related$ histopathological changes compared to HDT extracts.
