The fundamental principle of traditional Chinese medicine in treating diseases is to seek the root cause. In traditional Chinese medicine theory, it is believed that the occurrence of diseases is related to the imbalance of yin and yang in the body, and the key to treating diseases is to adjust the balance of yin and yang in the body and restore normal functions. Therefore, treating a disease must seek its root cause, which means that when treating a disease, it is necessary to deeply explore the underlying causes of the disease and treat it from the root to achieve the goal of curing the disease.
治病必求其本，这是中医治疗疾病的基本原则。在中医理论中，认为疾病的发生与机体的阴阳平衡失调有关，而治病的关键在于调整机体的阴阳平衡，恢复机体的正常功能。因此，治病必求其本，意味着在治疗疾病时，必须深入探究疾病的本质原因，从根源上进行治疗，以达到治愈疾病的目的。
