Abstract
Description
Technical Field
[0001] The invention belongs to the field of pharmaceutical preparations, and particularly relates to a Chinese medicine direct-take granule and a preparation method thereof. Background Art
[0002] At present, the main oral preparations of Chinese medicine include decoctions, pills, pastes, etc. Decoctions take a long time to boil, cannot be stored for a long time and are inconvenient to carry, and have obvious bitterness or odor; pills have large particles, which are not convenient for children to take, and they contain a lot of sugar or honey, which are easy to absorb moisture, and are prone to physical stability problems such as particle agglomeration and adhesion during storage; pastes often have harsh storage conditions and need to be refrigerated to prevent fermentation and deterioration. They are inconvenient to take, and their sticky texture needs to be dissolved in warm water. In addition, the preparation process is complicated, and it takes a long time to concentrate the paste, which is costly.
[0003] Because traditional Chinese medicine has many ingredients, it is difficult to prepare it into a preparation that has no bad taste and odor, is easy to take, and is physically stable. This is a technical problem that needs to be solved in this field. Summary of the Invention
