Problems solved by technology

[0003] There are obvious regional differences in the traditional usage habits of Chinese herbal pieces. The processing methods of the pieces are different in different regions. The dissolution rate is low and the utilization rate of medicinal materials is low, which seriously affects the curative effect of traditional Chinese medicine
[0004] The existing mode of use of decoction pieces mostly adopts the method of pre-prescription weighing and blending. Large-package decoction pieces are usually sold after unpacking. The identity of the medicine is poor, and there is uncertainty in the effective drug dosage. The types of decoction pieces currently used are limited to: slices, segments , block, powder, cake, glue, and extraction formula granules, there are the same species but their quality varies greatly, and the clinical efficacy is very different. The quality of medicinal materials and their decoction pieces is difficult to achieve uniformity; The clinical curative effect and drug safety are important; there are very few Chinese medicinal materials suitable for processing into gelatinized Chinese medicine decoction pieces, and they cannot be widely used; extraction formula granules, also known as Chinese medicine granule decoction pieces, decoction-free pieces, single-flavor Chinese medicine concentrated granules, are convenient, Fast, safe, hygienic, convenient for mechanized production, unified quality standards, easy to take, carry, and deploy; The torment process in the process of citing traditional Chinese medicine is eliminated, so that it loses the synergistic effect of co-decoction of various traditional Chinese medicines, and its efficacy is far inferior to that of traditional Chinese medicine decoction.
