Frostbite is a common winter disease caused by spasmodic constriction of small local arteries, obstruction of blood flow and tissue hypoxia, resulting in tissue cell damage and tissue edema, forming purplish-red edematous irregular erythema with burning and itching sensations, and in severe cases, blisters and ulcers. The Sui “Treatise on the Origin of Diseases” clarifies the etiology of the disease as “in the severe winter months, the wind and snow are exposed to cold and poisonous air, which injures the skin and congests the qi and blood, so that it is frozen, and the red pain becomes frostbite.” To the Ming and Qing dynasties, “Surgery Qixuan” proposed that the etiology of frostbite is related to the weakness of the body in addition to the cold attack, such as “…… there are also people with weak vital energy, who do not tolerate its cold.” Our department has been treating frostbite for several years after the beginning of the summer by adding Dosheng cream to treat winter and summer diseases, and hundreds of people are treated every year. Specifically, we apply the medication to the lesions and symptoms of the previous winter, and place the area covered with the cream in front of a PTC heater (220V, 50HZ, 600W) for 30 minutes, then wash off the medication. Once a day, 10 days of continuous treatment for a course of treatment. If the winter recurrence of the second course of treatment is required. Winter disease and summer treatment method originated from the “Su Wen – Four Qi Tuning Shen Da Lun” proposed in the “spring and summer nourishing Yang” health care rules, is one of the important methods of traditional Chinese medicine. According to the changes of yin and yang in Chinese medicine, the yang energy of the human body is more vigorous in spring and summer and weaker in autumn and winter. The human body is under the control of the annual rhythm of Yang-Qi changes formed by the long-term correspondence with nature. Therefore, although Yang deficiency is insufficient in all four seasons, it is influenced and promoted by the natural Yang-Qi flourishing in summer, and the Yang-Qi of the human body is at its peak in summer, so the deficient Yang has a tendency to move and tend to improve, and the condensed cold in the body can be easily removed and solved, so it can be treated by taking advantage of its potential to obtain good results.
