The present invention relates to a method for standardizing normalized a Geumsan black ginseng, and to a standardized material standardized through the method. The method comprises the steps of: drying a wild ginseng at a temperature of 90-96C for 3-5 hours; steaming the dried wild ginseng at 45-55C for 36-48 hours; drying the steamed wild ginseng at 40-60C for 2-4 hours; producing normalized black ginseng by repeating the drying step and the steaming step for 5-9 times; producing a first extract by firstly extracting the black ginseng by 70% ethanol; producing a second extract by secondly extracting the black ginseng remaining after the first extraction by 70% ethanol; producing a concentrate by filtering, mixing, and concentrating the first and second extracts; and producing a powder-type standardized material by freezing and drying the concentrate. The normalized black ginseng contains benzopyrene having an amount which is equal to or less than a standard value, or does not contain benzopyrene at all. Also, the normalized black ginseng has an antioxidant effect, and a small amount of improved ginsenoside which is beneficial to a human body is contained therein. The standardized material does not have genetic toxicity, and has an effect in adjusting blood sugar.
