This invention relates to the field of traditional Chinese medicine technology, specifically to a method for preparing concentrated Astragalus membranaceus pills and its application, including the following steps: (1) preparing a clear extract by alcohol extraction; (2) making pills by plastic molding; (3) drying the pills at a constant temperature. In the pill-making process, this invention selects 100-mesh Astragalus membranaceus mixed fine powder and adopts a mass ratio of clear extract to fine powder of 1:2. Since the 100-mesh powder has a uniform particle size and a moderate specific surface area, it can fully contact and bond with the clear extract, avoiding the problem of the pills being rough and cracked due to excessive particle size and the pills being too fine due to excessive moisture dissipation. The 1:2 ratio makes the soft material suitable for its softness and hardness, so that it will not be loose and difficult to form due to excessive powder ratio, nor will it cause adhesion and blockage of the mold due to excessive clear extract ratio. Combined with the gradient humidity soft material preparation technology, 60% purified water is added first and mixed evenly, and then the remaining water is added in two batches. Low-frequency vibration is applied simultaneously for mixing, which can make the internal humidity of the soft material uniform and the bonding force stable, thereby obtaining wet pills with smooth surface, round shape and no cracks.
