Traditional Chinese medicine was proposed more than 2,000 years ago in the Yellow Emperor’s Classic of Internal Medicine, and after long practice, Chinese medicine has gradually formed the theoretical systems of “prevention before illness”, “prevention after illness” and “prevention after healing”. Through long-term practice, TCM has gradually formed the theoretical system of “prevention before illness”, “prevention after healing” and “prevention after recurrence”, and formed a rich variety of technical methods. One of the important characteristics of TCM is the “winter and summer treatment”. What is “winter disease and summer treatment”, is to take advantage of the high temperature in summer, the body is full of Yang energy, adjust the balance of the body’s Yin and Yang, so that some of the persistent diseases can be restored. “Winter diseases” refers to certain pathologies that occur in winter or are aggravated in winter, such as vasculitis, atherosclerosis, diabetic foot, bronchitis, bronchial asthma, rheumatism and rheumatoid arthritis, etc., which belong to the cold or deficiency cold diseases in Chinese medicine. The “summer treatment” refers to the remission of these diseases in summer, taking advantage of the remission season to use internal and external methods to prevent the recurrence of old diseases in winter, or to reduce their symptoms. Why “summer treatment” for “winter diseases”? This is based on the preventive thinking of “treating the disease before it occurs” in Chinese medicine, and the principle of “unity of heaven and man” and “nourishing the yang in spring and summer” in Chinese medicine. The onset of diseases caused by cold is mainly in winter. Chinese medicine believes that the formation of disease, external causes is only one aspect, more important is the state of the human physique, suffering from the invasion of cold evil is often the body Yang Qi is not enough, the accumulation of cold evil does not dissipate more injury Yang Qi, resulting in internal cold. So it is said that winter diseases are mostly due to the invasion of cold as the external cause, and the patient’s physical Yang Qi deficiency as the internal cause. In winter, when Yin is strong, the patient’s Yang Qi is at a low ebb and the patient’s ability to receive external treatment is at a “bad time”, so the effect is slow. In summer, when the temperature rises, the natural yang energy rises to its peak, and the yang energy in the human body is also strong, if there is cold energy latent in the body that does not develop, take preventive and therapeutic measures to dispel the cold energy and help the yang energy, especially in the three volt days, when the skin coupons are open and the meridians are open, if the corresponding acupuncture points are selected for compressing, the drug can most easily penetrate into the acupuncture points by the skin and reach the disease directly through the meridians, which can promote sufficient yang energy in the body, and the cold energy latent in the body can be driven out. In the cold season, it is easy to resist the cold Qi and not to develop disease or less disease. Therefore, the best time to treat winter diseases in summer is during the three volt days in summer. The treatment and regimen of these winter diseases, which are weak in yang qi, will be carried out in the three volt days of summer, when yang qi is strong and does not develop, so as to achieve twice the effect with half the effort, which reflects the theory of Chinese medicine of “treating the disease before the disease instead of treating the disease”. Winter and summer treatment is applicable to the treatment of all deficiency cold diseases referred to in Chinese medicine. Many of the common diseases and illnesses in winter, the basis for their occurrence or onset is often formed or existed in the summer, but due to the exuberance of Yang Qi in summer, the Yang Qi of the human body is also encouraged, the human skin coup fully open, the internal disease evil not to wreak havoc; and in winter, the Yang Qi turns weak, the Yang Qi of the human internal convergence, so that the latent internal disease evil accumulate potential and rise. Therefore, to prevent and treat certain winter cold diseases, we should start from summer and prevent winter diseases in summer. At present, the most treated diseases in clinical practice are: asthma, chronic bronchitis, allergic rhinitis, chronic pharyngitis, chronic tonsillitis, recurrent colds, chronic gastritis, chronic colitis, chronic diarrhea and dysentery, rheumatoid arthritis, rheumatoid arthritis, frozen shoulder, low back and leg pain, frostbite, cold hands and feet, vasculitis, etc. All diseases with insufficient yang energy, cold pain and some immune deficiency. Whether taken internally or externally, summer treatment for winter diseases often uses a combination of medicine and acupuncture point compresses to stimulate positive energy, expel persistent evil, phlegm and blood stasis, unblock meridians, activate blood circulation, warm the meridians and disperse cold, so that the body’s yang energy is enriched, the ability to resist cold is enhanced, and the meridians are penetrated, thus achieving the goal of curing the root. There are many methods to treat winter diseases in summer, commonly used are acupuncture point compress, moxibustion, cupping, acupuncture point injection, gua sha, Chinese medicine, food therapy, etc., of which acupuncture point compress is most commonly used. Summer skin acupuncture points sensitive is the best time to treat chronic and persistent diseases, acupuncture point compress because of the use of different drugs and acupuncture points can play a variety of therapeutic effects, mainly through the transdermal absorption of drugs, play a stimulating effect on acupuncture points, so as to adjust the function of the internal organs, nourish the blood, balance yin and yang, improve and enhance the immunity of the body, to help eliminate evil, prevent and reduce the re-occurrence of disease. Fire cupping can make local tissues form a high degree of congestion, vascular nerves are stimulated, dilating blood vessels to increase blood flow. Vasculitis is an inflammation of the vascular wall itself, with the entire layer of the vascular wall involved in the lesion from the inside out, resulting in narrowing of the vascular lumen and poor elasticity, producing a series of symptoms. Early symptoms of vasculitis are: numbness of the limbs, coldness, pain, easy fatigue, soreness of the calves, weakening of the pulse, and gradual disappearance. Mid-term symptoms are: pain in the lower leg during activity, muscle twitching, especially obvious at night, intermittent claudication; late symptoms include continuous severe pain, dark red, dark brown skin, ulcers, blackening, necrosis. In cold weather, the lesion vasoconstriction and spasm, the ischemia of the extremity increases, and the appearance of limb symptoms and the incidence of gangrene increase significantly. It is important to start preventive treatment from summer to improve blood flow to the extremity and promote the establishment of collateral circulation to avoid recurrence or aggravation of the disease in winter. The vascular surgery department of our hospital has developed the winter disease summer treatment “expelling cold and eliminating pain cream”, which belongs to the category of acupuncture point dressing therapy, it is a combination of acupuncture point and medicine, both physical stimulation and chemical stimulation of drug absorption, which is a representative dressing drug for preventing and treating vasculitis-like diseases. Patients with the above-mentioned vasculitis-like disease symptoms can come to the clinic during the three volt days. Special reminder is that if the limbs are cold and numb and painful, the onset of cold weather, the symptoms reduce or disappear when it is hot, this may be the early manifestation of limb ischemia, therefore, in the summer should pay attention to eat less cold melons and fruits, do not sleep outdoors at night, avoid showering with cold water, prohibit sleeping on concrete, prohibit direct cold air conditioning or electric fan blowing for a long time, so as not to accumulate wind, cold and moisture in the body, damage Yang Qi, aggravating the disease. aggravate the disease.
