Abstract: A method for extracting herbs is provided to be able to obtain an herb extract containing many useful ingredients, and improve the extraction yield compared to other extraction method by performing a hot-water extraction, an ultrasonic wave extraction and a high hydraulic extraction in complex. The method comprises the steps of: (a) after adding solvent, the amount of which is 10 times that of herb, into the herb, hot-water extracting it at a temperature of 40-60 deg.C for 24 hours; (b) after extracting it obtained from the step(a) for 30 minutes using ultrasonic wave having a frequency of 20-40 kHz, freezing the extract under a temperature of -20 deg.C and crushing it; and (c) after extracting it obtained from the step(b) for 1-5 minutes under the pressure of 200-300 mPa using a high hydraulic extractor, filtering under reduced pressure, concentrating and freeze-drying it.
