Objectives: The purpose of this study was to investigate the acute toxicity with oral administration in ICR mice of Ohyaksungi-san fermented with Lactobacillus sp. Methods: In single oral administered toxic test, four groups were administrated different dosages(0, 1250, 2500, 5000 mg/kg) of fermented Ohyaksungi-san. After single oral administration, we observed number of death, clinical signs, body weight changes, hematological values and autopsy. Results: Compared with the control group, we could not find any toxic signs in the mortalities, clinical signs, body weight changes, necropsy findings and hematological values in all treated groups (1250, 2500 and 5000 mg/kg). Conclusions: These results indicate that the $LD_{50}$ value of fermented Ohyaksungi-san extract might be over 5000 mg/kg and it have no side toxic effect to ICR mice
