A method for treating a human or an animal having a disease selected from the group consisting of diabetes, hyperglycemia, abnormal glucose tolerance, insulin resistance, arteriosclerosis, obesity, dyslipidemia, fat liver and mixtures thereof comprising:
- administering to the human or animal having the disease a persimmon leaf extract which is obtained by a process comprising extracting persimmon leaves with a 40-60% ethanol-water mixture to yield an ethanol/water extract of persimmon leaves;
- adsorbing the ethanol/water extract of persimmon leaves onto a column packed with an octadecylsilyl-bonded silica gel;
- and then performing an elution with a 5-10% acetonitrile-water mixture to yield the persimmon leaf extract.
