Uhwangchungsimwon(UC) is widely used as a herbal medicine on various circulatory disorders in Korea. The objective of this investigation was to characterize the acute, subacute hepatotoxic potency of orally administered UC in rats. In the acute and short-term studies, male rats of 150~170g were gavaged with 0, 7.5 g/kg once daily for up to 1, 5, 10 consecutive days. No differences in body weight, serum enzyme activities, absolute and relative liver weight and histopathological examination on liver between control and UC-fed groups were found. In the subacute study, UC was administered orally to both sexes of rats for 30 days(0, 1.875, 3.75 or 7.5 g/kg/day). There were no-doserelated hepatotoxic signs of general symptoms, body weight gain, water consumption and serum biochemical analysis. Slight decreases of food consumption observed at 3.75 and 7.5 g/kg groups of both sexes were due to be full of UC fed. Gross necropsy and histopathology revealed no evidence of hepatotoxicity related to UC. Our data indicate that hepatotoxicity was not caused by administration of UC up to 7.5 g/kg/dayfor 30 days in rats.

Objectives : This study was conducted to assess the effect of Uhwangchungsimwon on the autonomic nervous system. Methods : Eligible subjects were enrolled from healthy people in their 20s-30s. They were divided into two groups, the UC group (n=22) and the control group (n=20). We monitored ECG from 14:00 to 18:00 in both groups. In the UC group, subjects were administered UC at 15:00. HRV analysis was conducted at 14:00, 16:00, and 17:00 for 512 seconds. Results : The degree of LF/HF ratio change was significantly higher in the UC group at 1 hour after administration. Conclusion : We suggest Uhwangchungsimwon may be useful for stabilization of the autonomic nervous system by activating parasympathetic nerve in healthy people.
