The present invention relates to a method for extracting a medicinal herb essence and, specifically, to a method for extracting a medicinal herb essence, in which a medicinal material and water are fed into a medicinal herb extraction container, and then inner and outer portions of the medicinal herb are entirely and uniformly heated and steamed through an application of heat at normal pressure, and here, the steam generated during the heating is cooled, condensed, and collected, and then repeatedly circulated to the medicinal herb extraction container, such that the medicinal herb essence is continuously extracted by the steaming process at normal pressure and, if necessary, the collected condensate water containing active ingredients of the medicinal herb is mixed with the extracted medicinal herb essence. The medicinal herb essence of the present invention may be prepared by re-circulating the steam condensate water, which is obtained during the steaming process of the medicinal herb and contains active ingredients of the medicinal herb, or by separating some of the condensate water and then mixing same with a steamed and extracted medicinal herb essence, so that the medicinal herb essence obtained by the present invention has more excellent medicinal herb flavor and aroma and increases the uptake of active ingredients of the medicinal herb, which are contained in the condensate water, compared with a medicinal herb essence obtained through general steaming, and thus, the present invention has an advantage in that an extract of the medicinal herb essence having superior efficacy can be prepared.La présente invention concerne un procédé permettant dextraire lessence dune plante médicinale et, précisément, un procédé permettant dextraire lessence dune plante médicinale dans lequel une matière médicinale et de leau sont introduites dans un récipient dextraction de plantes médicinales les parties internes et externes de la plante médicinale sont ensuite entièrement
