Abstract
Objectives : This study was conducted to evaluate the acute toxicity and safety of Ssanghwa-tang (Shuanhetang in Chinese, Sou-wa-to in Japanese) in Crl : CD Sprague-Dawley (SD) rat though the current regulatory guideline. Methods : In this study, 10 rats of each sex were randomly assigned to two groups of 5 rats each and were administrated singly by gavage at dose levels of 0 and 2000 mg/kg/day of ssanghwa-tang water extract (SHT). After single administration of SHT, mortalities, clinical signs, body weight changes, gross findings were observed for the 15-day period. Results : Acute toxicity tests revealed that a single oral administration of SHT at dose levels of 2000 mg/kg did not affect clinical signs, body weight, and gross findings, evaluating the safety of SHT. The SHT treatment did not result in any toxicologically significant changes in mortality, clinical signs, body weight changes. Conclusions : These results showed that the single oral administration of SHT did not cause any toxic effect at the dose levels of 2000 mg/kg/day in rats. In conclusion, the median lethal dose (LD50) of SHT was considered to be over 2000 mg/kg/day body for both sexes.
