The invention relates to a device and method for preparing liquid from solid materials such as medicinal materials. It includes liquid and materials for preparing the liquid at the beginning and the end of the process. The device uses a steam generator, an intermediate switch valve and a material chamber, which are connected sequentially with pipes, and further includes an outlet pipe, which is at the bottom of the material chamber. The method involves the steps of: distillation and absorption; immersion; and repetition. The device and method for preparing liquid alternates the distillation and immersion steps, which reduces harmful substance in the prepared liquid that would otherwise occur by conventional methods. The method not only extracts soluble effective matter, but also reduces loss of volatile effective matter. Ultimately, the method makes the steps for preparing liquid simple and clear, and it can prepare liquid quantitatively, effectively and without pasty and shrinkable characteristics. The device may be automatically controlled by an electric control circuit, thereby avoiding operational errors that are common with manually operated, conventional devices.
