Objectives: In this study, it was carried out to evaluate the acute oral toxicity of Root of Polygala teunifolia Willd. in Sprague-Dawley (SD) rats.
Methods: Male and female rats were administered orally with Root of Polygala teunifolia Willd. water extract of 1,000 mg/kg (low dosage group), 2,000 mg/kg (middle dosage group) and 4,000 mg/kg (high dosage group). We daily observed number of deaths, clinical signs and gross findings for 7 days. After 7 days, we measured body and organs weight. Also we analyzed hematological changes.
Results: No dead SD rats and no clinical signs were found during the experiment period. Also other specific changes were not found between control and treated groups in hematology and serum biochemistry. But we found out histopathological changes in liver fat tissues of female. In addition, there were no significant changes of gross body and individual organs weight.
