Chinese medicine has always attached importance to the prevention of diseases. The concept of “treating the undiseased” first appeared in the Yellow Emperor’s Classic of Internal Medicine, and was proposed in Su Wen? In the “Four Qi Tuning Shen Da Lun”, it is proposed: “Therefore, the sage does not treat the sick to treat the unwell, and does not treat the chaos to treat the unrest. If the disease has become and then the medicine, chaos has become and then the treatment, like thirst and wear well, bucket and cast cone, is not also late”, vividly pointed out the importance of “treating the untreated disease”. According to modern medical theory, the health status of the population is divided into three kinds: one is the healthy state before disease; the second is the state before disease; the third is the state before disease. The “treatment of the untreated disease” is aimed at the above three states and has the following functions. This is the highest goal of medicine, the principle of treatment for the state of health before disease, and the highest state that a highly skilled doctor should pursue. In terms of “treating diseases before they occur”, we advocate green therapies such as acupuncture, massage and Chinese herbal medicine. Popular fitness programs such as taijiquan, aerobics, yoga, etc. can help people to strengthen their bodies and enhance their physical fitness, medicinal porridge, medicinal tea, preferably under the premise of a clear state of their own physical fitness, in addition to a healthy and regular life and a calm mind is also a vital measure to prevent disease. The second is to treat the disease and prevent the disease from developing: this means that measures should be taken to treat the disease at the beginning before there are obvious symptoms, so as to avoid the imbalance of the body from continuing to develop, which is the treatment principle of the latent disease. By analyzing the patient’s physical and mental state, confirming his body’s cold, heat, deficiency and yin-yang bias, and actively improving the special physique to enhance his resistance, TCM physical identification can prevent the occurrence of related diseases by preventing the causes of special people. For example, if a subhealthy person is tired and insomniac all day long and lacks enthusiasm, through physical identification, we believe that he is suffering from liver qi stagnation, so we should give acupuncture, massage or cupping stimulation on acupuncture points such as Liver Yu, Spleen Yu, Tai Chong and Foot San Li, in order to de-stimulate liver qi and regulate the qi of the internal organs, so that liver qi can be drained and the functions of the internal organs can be brought into balance, and the organism can be restored to a healthy state. Third, the disease is treated early, to prevent the transmission: refers to the disease already exists, early diagnosis, early treatment, to prevent it from the superficial into the deep, or the occurrence of internal organs of the transmission. This is the principle of treatment for the disease that has not been transmitted. For example, for hypertensive patients, we have to prevent the complication of heart, brain and kidney changes; for stroke patients, while their vital signs are stable, we have to treat their hemiplegia and speech disorders as early as possible. In addition, there are also post-milligram regimen, prevent its recurrence: refers to the first healing of the disease is still deficient, the evil gas to stay, the body is in an unstable state, the body function has not fully recovered, we should pay attention to regimen, in order to promote and mention early recovery and prevent the recurrence of disease. Even for the first recovery from a cold, patients should pay attention to avoid wind and cold, and rest more; and post-surgery patients are more qi and blood, increase the diet and nutrition and appropriate rehabilitation exercise is extremely important.
