Problems solved by technology

[0004] In the production and use for many years, the inventor found that the above-mentioned traditional technology has the following defects: 1. The extraction rate of active ingredients is low, and the recovery rate of active ingredients in the original process is generally 45-60%; 2. High energy consumption; 3. The bioavailability is low, especially the medicinal materials used as raw powder. Due to the low grinding fineness, the dissolution rate of the active ingredients is slow, which affects the curative effect and the utilization rate of the active ingredients.
4. Capsule contents (granules) are prone to moisture, which affects the stability of quality
