This is the therapeutic principle that TCM adopts in treating diseases. The occurrence, development and changes of a disease are involved by various factors, including the climate, geographical environment, the patient's constitution, sex and age etc. Therefore, when treating a disease, the doctor must take the three conditions into account, and make a concrete analysis of concrete conditions and deal with them in different ways, thereby working out an appropriate therapeutic method.
