Four kinds of decoctions (Wolbi-tang, Wolbigachul-tang, Wolbigabanha-tang and Wolbi-tang with Psyllium Husk diet)was prescribed to examined the therapeutic effects on hyperlipidemia. Four decoctions prepared from the prescriptions were respectively administrated to the corpulent rats induced by a high cholesterol diet. Wolbi-tang mollified the increasing rate of the body weight, and decreased the amount of food eaten. It slightly increased the concentrations of blood Tc, blood TG, blood FFA, and lipids in feces, and decreased the contents of blood HDL-c. Wolbigachul-tang mollified the increasing rate of the body weight, and decreased the amount of food eaten. It decreased the amount of FFA and HDL-c lipids in the blood. Wolbigabanha-tang mollified the increasing rate of the body weight, and decreased the amount of food eaten. Also, it decreased the concentrations of blood glucose. However, it increased the content of blood HDL-c. Wolbi-tang with Psyllium Husk diet mollified the increasing rate of body weight, and decreased the amount of food eaten. Also, it slightly decreased the concentrations of blood TG and blood FFA, but increased the concentrations of blood Tc. Considering the above results, four kinds of decoctions(Wolbi-tang, Wolbigachul-tang, Wolbigabanha-tang and Wolbi-tang with Psyllium Husk diet) could be applied for the treatment of obesity, and Wolbigabanha-tang would be the most recommendable among them.
