Abstract:The experiments have shown that there is incompatibility on anti-stress because the action of RadixFinseng alone is stronger than that of Radix Ginseng and Faeces Trogopterori combined, but there is little incompati-bility on non-specific immune function when both are used. The analysis of chemical composition of Radix Ginseng hasindicated that the acquired rate of total saponin from the semifinished products and Rg_1 of Radix Ginseng is markedlyincreased when the two drugs are decocted together. The results suggest that the traditional theory is limited in hold-ing that Radix ginseng and Faeces Trogopterori are incompatible with each other.
