Objectives: In this study, we investigated the 4-week repeated-dose oral toxicity of gami-jakyak gamcho buja decoction (Mecasin) to develop safe treatments. Methods: In order to investigate the 4-week oral toxicity of Mecasin, we administered Mecasin orally to rats. Sprague-Dawley (SD) rats were divided into four groups of five male and five female animals per group: group 1 being the control group and groups 2, 3, and 4 being the experimental groups. Doses of Mecasin of 500, 1,000, and 2,000 mg/kg of body weight were administered to the experimental groups, and a dose of normal saline solution of 10 mL/kg was administered to the control group. We examined the survival rate, weight, clinical signs, and gross findings for four weeks. This study was conducted under the approval of the Institutional Animal Ethics Committee. Results: No deaths occurred in any of the four groups. No significant changes in weights or food consumption between the control group and the experimental groups were observed. Serum biochemistry revealed that some groups showed significant decrease in inorganic phosphorus (IP) (P < 0.05). During necropsy on the rats, one abnormal macroscopic feature, a slight loss of fur, was observed in the mid dosage (1,000 mg/kg) male group. No abnormalities were observed in any other rats. In histopathological findings, the tubular basophilia and cast of the kidney and extramedullary hematopoiesis of the spleen were found. However, those changes were minimal and had occurred naturally or sporadically. No other organ abnormalities were observed. Conclusion: During this 4-week, repeated, oral toxicity test of Mecasin in SD rats, no toxicity changes due to Mecasin were observed in any of the male or the female rats in the high dosage group. Thus, we suggest that the doses in a 13-week, repeated test should be 0, 500, 1,000, and 2,000 mg/kg respectively.
