Traditional Chinese medicine, including Chinese herbal medicines, Chinese herbal pieces and Chinese patent medicines, is the three pillars of Chinese medicine industry. Among them, Chinese herbal medicines are the raw materials of Chinese herbal pieces, and Chinese herbal pieces are the raw materials of Chinese patent medicines. Traditional Chinese medicine decoction is a form of traditional Chinese medicine, which is used for the prevention, treatment and health care of clinical diseases like Chinese patent medicine. It is only possible to add and subtract Chinese herbal pieces in clinic, which is very flexible and more in line with the "personalized administration" that must be carried out for different patients. Therefore, Chinese herbal pieces are still the form of clinical use of Chinese medicine at present, although the sales volume of Chinese patent medicines has exceeded that of Chinese herbal pieces at present, which is determined by many factors. One is that the price of Chinese patent medicine is much higher than that of decoction, and the other is that the application form of Chinese herbal pieces is not suitable for the needs of modern people, that is, it is inconvenient.
