The objects of this study are to evaluate the effects of the "Heysong japanese green tea" on the human subjects who are dyslipidemia. In this trial, 40 healthy subjects whose ages are 18\~65 years old (20 for placebo and 20 for experimental) will be included. The total experiment will be 16 weeks and the intervention period will be 12 weeks, within which, at wk 0, 2, 8, 14 and 16, serum triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) values would be measured.
