“It reveals that the human body corresponds to the four seasons of heaven and earth, and the only way to keep the human body healthy and free from diseases or serious illnesses is to follow the changes in the external qi of the four seasons and take appropriate health care methods to adjust the pattern of work and rest and living. “Therefore, spring and summer nourish Yang and autumn and winter nourish Yin can be regarded as an important basis for “treating the disease before it happens”. In other words, spring and summer nourish the yang energy of the human body, and autumn and winter nourish the yin energy of the human body, in order to maintain the synergy between the human body and the natural qi. The ancients put forward the concept of “winter disease and summer treatment” based on the concept of “spring and summer nourishing Yang”. “Winter diseases” refers to certain deficient, cold, internal and yin diseases that tend to occur in winter or are easily aggravated in winter, resulting in long-term recurrence of deficiency of qi in the internal organs and lack of yang qi, specifically in the kidneys, lungs, spleen and stomach, nose, limbs and meridians, such as cough, asthma, rhinitis, chronic diarrhea, cold and stiff joints, muscle aches, fear of cold, susceptibility to sensation, etc. Summer treatment” means that in summer, when the Yang energy of the body is at its peak, we should follow the nature and use the natural “warmth and heat” to warm the Yang energy, disperse the cold and expel the evil, activate the blood and open the veins, and enhance the positive energy of the body, i.e., apply medication to specific acupuncture points on the human body. This means that the body is treated or prevented by applying medication, injecting medication, acupuncture, moxibustion, buried threads, gua sha, cupping or taking medication internally, so as to remove the cold energy deposited in the body, adjust the body’s yin and yang, so as to achieve a balance of yin and yang and recover from chronic illnesses. The three volt days, is the highest temperature of the four seasons of the year, when the natural yang energy is strong, the body is full of positive Qi, Qi and blood flow, Yang Qi floating on the surface, the human couples in the open state, so at this time in the acupuncture points on the medicine, moxibustion, acupuncture, cupping, etc., easier to get gas, dredge the meridians, through the meridians of Qi and blood running effect, adjust the function of the internal organs, to achieve twice the result with half the effort. So winter illness and summer treatment means doing active treatment during the remission period of the disease. While the disease is stable, we can accelerate the improvement of the body to achieve the purpose of treating the disease. “Do not treat the disease to treat the disease”, “winter nourishment three nine tonic prosperous, summer treatment three volt line needle busy” this is to say the winter disease summer treatment commonly used “to play volt injection”.
