The utility model relates to a medical liquor extraction device, which comprises an extraction tank. The extraction tank is connected with a condenser through a pipeline, the condenser is connected with a cooler through a pipeline, a cooler is connected with an oil and water separator through a pipeline, and the oil and water separator is connected with the extraction pot through a pipeline. Besides, both inlet pipelines of the condenser and the cooler are provided with water inlet valves. The medical liquor extraction apparatus has the advantages that circulation of extracts is realized, extraction process is speeded up, extraction speed is increased, uniformity of effective compositions in extracts is improved, loss of medical liquor is controlled, output is increased, consumption is reduced (and is one quarter of the original value), effective compositions can be extracted completely, and product quality is improved by the aid of the condenser, the cooler and the oil and water separator arranged on the extraction tank.
