The invention provides a preparation method and application of a soft fiber traditional Chinese medicine decocting-free preparation and belongs to the technical field of traditional Chinese medicine preparation. The preparation method includes the sequential steps: subjecting traditional Chinese medicinal materials to dicing or slicing, boiling and pulping, carrying out ethanol extraction and ultrasonic-assisted extraction, performing inorganic ceramic membrane filtering, concentrating and spray-drying to obtain powder, sterilizing the powder, and performing vacuum packaging to obtain finished products. The problems that in extraction by a conventional single method, utilization of raw materials is low, effective ingredients are badly destructed and extraction efficiency is low are solved, and the prepared preparation is more convenient to use and is more suitable for modern people's quick life. The whole technical process is simple to control and green, various process steps are synergistic, the preparation method is higher in applicability and extraction efficiency, the active ingredients are protected effectively, and product utilization is better increased.
