This study was conducted to investigate the antitoxic effects of Radix Menispermi extracts against cadmium toxicity. The experimental rats were divided into 5 groups such as control group, cadmium alone treatment group and simultaneous treatment groups of cadmium and three doses of Radix Menispermi extracts. Each group was administered with different dose of Radix Menispermi extracts such as 0.55 mg, 1.10 mg, 1.65 mg/kg wet weight in pallets for 12 weeks. Cadmium Chloride $(CdCl_2)$ was administered by 4 mg/kg body weight. The results were summarized as follows: 1. The simultaneous administration of cadmium and Radix Menispermi significantly more decreased cadmium concentration in liver tissues compared to the administration of cadmium only (P < 0.05). 2. When blood were measured, no significantly difference in haemoglobin, haematocrit, erythrocyte values compared to the administration of cadmium only. 3. The simultaneous administration of cadmium and Radix Menispermi more increased metallothionein concentration in liver than the administration of cadmium only (P < 0.05). 4. There were the histopathological slight changes in the liver and kidney tissues of rats.
