The traditional Chinese medicine（TCM）has always been an important part of Chinese culture, and its good effect in Health-Preservation is highly regarded in the East and mysterious in the West. However, there are many problems in the process of TCM diagnosis, such as long time-consuming to use “4 diagnosis methods” and obscure TCM terms. We design a pre diagnosis machine “HERB” of TCM, which helps patients diagnose themselves before going to hospital with the help of sensors, AI and other technologies, so as to improve the efficiency of seeing a doctor.
