Abstract

Context: Orostachys japonicus (Crassulaceae) is referred to as Wa-song in Korea. It is used as an anti-inflammatory, antifebrile, hemostatic, and anti cancer agent, and as an antidote. Objective: The purpose of this study was to evaluate the acute toxicity of the ethyl acetate fraction of O. japonicus (OJE) after the oral administration in Balb/c mice of both sexes. Materials and methods: Mice were oral administered a single doses of 500, 1000, and 2000 mg/kg of body weight and were monitored for 14 d. Biochemical parameters [aspartate amino transferase (AST), alanine amino transferase (ALT), alkaline phosphatase (ALP), total protein (TP), globulin (GB), total cholesterol (TC), triglyceride (TG), blood urea nitrogen (BUN), and creatinine (CR)] and histopathological examination of liver were performed. Results and conclusion: No animals died and no toxic changes were observed in clinical signs, body weight, and organ weight. The LD50 of orally administered OJE was higher than 2000 mg/kg/d in both sexes. No toxicological findings were found in biochemical parameters. In histophathological examination, neutrophilic infiltration was observed at a dose of 2000 mg/kg group in both sexes. These finding suggest that oral administration of OJE does not produce acute toxicity. Therefore, these results could provide satisfactory preclinical evidence of safety to launch clinical trials on standardized formulation of OJE to be a biohealth product. [ABSTRACT FROM AUTHOR]
