Abstract
|
|
|
Objectives: This study aimed to evaluate the single oral dose toxicity of Seonpyejeongcheon-tang (SJT) in male and female Sprague-Dawley rats.
Methods: In this single oral toxicity study, rats were orally administrated in a single dose of 0 or 5,000 mg/kg SJT. There were 7 rats in each group. After single administration, mortality, clinical signs, body weight changes and gross pathological findings were observed for 14 days. Organ weight, clinical chemistry and hematology were tested after 14 days.
Results: There was no mortality or other clinical signs for 14 days. There were also no significant differences in body weight, organ weights, hematological and serum chemical parameters between the SJT and control groups.
Conclusions: The results obtained in this study suggest that the 50% lethal dose of SJT is over 5,000 mg/kg, so this finding can be expected to provide scientific evidence for the safety of SJT.
