Objective : This study was carried out to evaluate the liver toxicities of Wild Aconiti Tuber decoction. Methods : The amounts of aconitine in the methanol extract of Wild Aconiti Tuber was measured by HPLC. Safeties was studied by LD50 in mice. Liver toxicities were evaluated histologically and by CBC, blood chemistry after 2 weeks of 0.4g/kg/day clinical dosage oral administrations in rat. Results : 1. The amounts of aconitine in the methanol extract of Wild Aconiti Tuber is $1.697{\pm}0.052mg/g$. But aconitine was not detected in the water decoction of Wild Aconiti Tuber. 2. To evaluate LD50 and safeties of Wild Aconiti Tuber decoction, ICR mice were given high dose of 2, 5, 10g/kg for single time and were observed for 2 weeks. There were no dead animal and abnormal clinical sign and no abnormalities at the autopsy. So, LD50 was admitted to higher than 10g/kg. 3. After 2 weeks of 0.4g/kg/day clinical dosage oral administrations in rat, there was no significant change in the CBC and blood chemistry. 4. In the liver tissues of clinical dosage, mitotic figures, apoptosis and individual cell death were observed, but clear liver toxicities like fatty liver or necrosis were not observed. the liver tissues of high dose in mice, hydropic changes were getting severe as dose grows. Conclusions : According to the results, though aconitine was not detected in the Wild Aconiti Tuber decoction, 0.4g/kg/day 2 weeks p. o (clinical dosage) group showed weak changes in the liver tissues and high dose group showed liver toxicities like hydropic changes.
