Problems solved by technology

[0010] The main problems of the existing preparation method are: the original medicinal material is directly crushed and mixed with honey to make a honeyed pill, which is not easy to sterilize. During the storage process, problems such as insects, mildew, dryness, and sandback often occur, and the quality is difficult to control.
Taking too many doses leads to slow absorption and marked effect, and the appearance is not easy for patients to accept. In addition, the pain is severe and unbearable when migraine attacks, and rapid pain relief treatment is needed, but Damiwan does not have this feature. Many reasons limit this traditional Chinese medicine. The clinical use of proprietary medicines violates the principles of suitability for disease and suitability for medicine
