Abstract: The concept of "preventive treatment" is introduced into the prevention and treatment of hypertension with Chinese medicine throughout the whole cycle, and the three-level prevention and treatment strategy of hypertension with Chinese medicine is strengthened from the three aspects of "preventing the disease before it occurs, preventing changes after the disease occurs, and preventing failure after changes occur", so as to intervene in the pre-hypertension stage early, block the progression of hypertension, protect target organs, prevent complications, improve the quality of life of patients. The strategy of the whole-cycle prevention and treatment of hypertension with Chinese medicine under the guidance of the concept of "preventive treatment" is also explored, providing a theoretical basis for the application of Chinese medicine in the prevention and treatment of hypertension.
