Chinese medicine has always attached importance to the prevention of diseases. As early as more than 2,000 years ago, the Nei Jing put forward the idea of “treating diseases before they occur” and emphasized “prevention before they occur”. The four qi tune Shen Da Lun said: “The sage does not treat the sick to treat the sick, not to treat the chaos to treat the chaos. …… the disease has become and after the medicine of, chaos has become and after the treatment of, like thirst and wear well, bucket and cast cone, not also late. Here is a vivid suggestion of the importance of “treating the disease before it happens”. And those who know how to “cure the untreated disease” are called “superior workers”. Su Wen? The Eight Divine Ministries of the Supreme Worker” says: “The Supreme Worker saves the sprout, the Lower Worker saves the established, and saves the defeated”. In later times, there were new developments of this idea of prevention, such as Sun Simiao’s “Thousand Gold Formula” in Tang Dynasty. The nature of the health? Residence method” clearly pointed out: “must be adjusted every day, massage guide for good, do not take the health will always be, always need to be safe not forgetting the danger, prevention of diseases.” Prevention-oriented, is one of the major policies of China’s health work. The idea of “treating the disease before it happens” in Chinese medicine coincides with the principle of prevention in modern medicine. At present, the incidence of cardiovascular disease is increasing and has become one of the three major killers of human health. With the development of evidence-based medicine and cardiovascular interventional techniques, modern medicine has made rapid progress in the cardiovascular field, but the morbidity and mortality rates of many common cardiovascular diseases are still high. Strategies such as prevention first, combination of prevention and treatment, universal mobilization, and community intervention are attracting more and more attention from governmental departments and clinicians. Traditional medicine, with a history of thousands of years, has its own characteristics in this area. For example, the primary prevention and secondary prevention of coronary heart disease, hypertension and other highly prevalent cardiovascular diseases are gaining more and more attention, which is actually in line with the principle of “prevention before illness, prevention after illness” in Chinese medicine. For example, interventions for common risk factors of cardiovascular diseases such as hypertension, hyperlipidemia and hyperglycemia, including antiplatelet aggregation, lipid regulation, hypotension, hypoglycemia, anticoagulation, etc., have already been agreed upon, while Chinese medicine has long proposed to avoid the invasion of the “six sexes” in nature, avoiding happiness, anger, sadness, pity, fear and fright The basic prevention and control principles of the above interventions have already been included in Chinese medicine, such as avoiding the invasion of the “six sexes” in nature, avoiding the harm of the “seven emotions”, avoiding dietary indiscretion and overwork and injury, etc. The idea of “treating the disease before it occurs” in Chinese medicine also includes the current modern medical emphasis on active health education among people at high risk of cardiovascular disease and patients, and ancestral medicine has long advocated that people should regulate their spirits, strengthen exercise, pay attention to diet, and live a regular life, that is, to strengthen the righteousness and resist disease; at the same time At the same time, it advocates that once people are sick, they should be diagnosed and treated at an early stage and prevented from changing according to the law of disease transmission and so on. Some of these dietary remedies are easy to make and inexpensive, so they deserve our attention. The following is a few food therapy prescriptions for cardiovascular patients: 1.
