Decursin Safety from Root of Angelica gigas in Rats

The subacute intraperitoneal toxicity of decursin was investigated in Spargue-Dawly（SD） rats. The rats were treated with decursin at a dose of 125 and 250 mg·kg-1·day-1for 4 weeks. All animals were observed daily for clinical signs. Their body weights were recorded weekly, no mortality was observed in two doses of 125 and 250 mg·kg-1of decursin. There were no significant differences in the clinical observations, body weight, food and water consumption, hematology, blood chemistry, gross pathological examination or organ weight between control and treated animals of both sexes. In conclusion, no evidence of a subacute toxic potential was observed in this study and no indication for adverse effects was noted at a dose level of 250 mg·kg-1·day-1.
