This study was performed to observe the effect of hyulbuchukeo-tang and its component groups on recovery of hepatoxicity in alloxan treated rats. The experimental group was divided into 3 groups: hyulbuchukeo-tang(HCT) and its components groups, sayeok-san(H-sa) and dohong-samul-tang (H-do). The results were obtained as follows: 1. The level of Glucose was considerably reduced by HCT, H-sa, H-do with high significancy. 2. In the change of GOT activity, HCT and H-do were decreased with high significancy, H-do was decreased with some significancy. 3. In the change of GPT activity, HCT was decreased with high significancy, H-sa and H-do were decreased with some significancy. 4. In the change of ${gamma}-GPT$ activity, HCT was decreased with high significancy, H-do was decreased with some significancy. 5. In the change of ALP activity. only HCT was decreased with some significancy. 6. In the change of LDH activity, HCT was decreased with high significancy, H-sa and H-do were decreased with some significancy. 7. In the change of bilirubin contents. only HCT was decreased with some significancy. As result, hyulbuchukeo-tang(HCT) has significant effects on recovery of hepatoxicity, and its components groups. sayeok-san(H-sa) and dohong-samul-tang(H-do) have some effects. It suggests that sayeok-san(H-sa) and dohong-samul-tang(H-do) have more effects on recovery of hepatoxicity in case of the combination of the two (that is hyulbuchukeo-tang) than in case of the separation.
