Among them, "five internal organs are injured, and poverty will reach the kidney" comes from the seventh book of "Treatment". This paper mainly introduces the basic principles and methods of TCM treatment, including syndrome differentiation, regulating yin and yang, and regulating qi and blood. Among them, "when the five internal organs are injured, the poor will reach the kidney" means that when the five internal organs diseases develop to a certain extent, the kidney will often be affected, because the kidney is the innate foundation of the human body and has important regulatory and metabolic functions. Therefore, in the treatment of five zang-organs diseases, we should also pay attention to conditioning the kidneys in order to achieve the effect of comprehensive treatment.
