In the prime of summer, traditional Chinese medicine treatment for winter diseases has become a healthy choice for many people, with the Sanfu patch being particularly popular. Pan Fangfang, Deputy Director of the Rehabilitation Department of the Linping Campus of the Second Affiliated Hospital of Zhejiang University, reminds that the Three Fu Tie is not suitable for everyone and cannot be used to cure all diseases. At the same time, due to the different ingredients in the prescription, it is recommended that the public apply it after being diagnosed by a doctor. It is not recommended to purchase it online and apply it on their own. San Fu Tie is a traditional Chinese medicine treatment method for winter diseases and summer treatment. It often uses some medicines that warm yang, dispel cold, remove dampness, and unblock collaterals to make pills, which are applied to specific acupoints in the human body, using the skin stimulation of the medicine to have a therapeutic effect. Because the best time for treatment is during the summer solstice period each year, it is called the summer solstice patch. According to traditional Chinese medicine, applying on the hottest three fu days of the year can treat various diseases that are prone to occur in winter and worsen in winter, as well as diseases that repeatedly cause entanglement in organs, meridians, and other systems that are difficult to heal. After continuous application for three years or more, most of the above diseases can significantly reduce symptoms and incidence rate. She reminded that it is best to use three consecutive years of San Fu Tie to consolidate the therapeutic effect, and not to "fish for three days and dry the net for two days". At the same time, San Fu Tie is targeted and cannot cure all diseases. Recently, Pan Fangfang received a patient in his 70s. The patient reported that they had prepared some Sanfu patches at the health center at their doorstep, but after using them, their body did not seem to improve and their sleep was even worse. After carefully inquiring about her usual symptoms, Pan Fangfang found that the patient belongs to the typical type of "yin deficiency and excessive fire" based on tongue coating and pulse conditions, which is not suitable for the treatment of Sanfu plaster. "Not everyone can apply the 'Three Fu Tie', so be sure to avoid adding fuel to the fire." Pan Fangfang explained that the principle of San Fu Tie is to use objective conditions such as hot summer climate, the most vigorous Yang energy in the human body, and the opening of the body's surface meridians. By applying traditional Chinese medicine to specific acupoints such as Tian Tu, Da Zhu, and Gao Xian, it achieves therapeutic effects that are difficult to achieve in other seasons. However, more and more people are now aware of the health benefits of treating winter diseases and summer illnesses. Whenever there are lung diseases such as coughing and wheezing, they will come and apply a patch. In fact, coughing and asthma can be divided into cold and hot. If there are often symptoms such as hot flashes, night sweats, restlessness and thirst, and tongue redness and lack of coating, once warm yang medicine is applied, it will actually add fuel to the fire. In addition, those who are allergic to the application of drugs or dressing ingredients, those with skin allergies and scar constitution, and those who have wounds, ulcers, and infections on the skin of the application site, patients with severe cardiopulmonary disease, severe diabetes, and patients with malignant tumors are not suitable for the use of three volt patches. It is also worth noting that in terms of usage, it is not recommended to apply the Sanfu patch at home. "Nowadays, health preservation is very popular, and technologies such as self testing and identification of physical fitness, AI diagnosis, etc. are advancing rapidly. Even if the software is professional enough, patients without professional medical knowledge background need to question whether they can make correct judgments on traditional Chinese medicine terms such as' hot flashes and night sweats, '' five heart restless heat ', as well as tongue coating and pulse conditions." Pan Fangfang said. At the same time, the ingredients and effects of San Fu Tie prescriptions are different. There are various San Fu Tie pills available online, which may have varying quality and pose certain safety risks. Therefore, imitating the application at home may not be correct or appropriate. Experts remind that according to the Notice of the State Administration of Traditional Chinese Medicine on Strengthening the Application and Management of Acupoint Application Technology for Winter and Summer Treatment of Diseases, Sanfu plaster must be carried out in medical institutions. Any health center, health care facility, beauty salon, etc. cannot provide standardized three fold patch services due to the lack of professional medical personnel and medical institutions. To ensure the safety and health of the public, it is recommended that everyone go to a formal and qualified medical institution for patch treatment. (Lai Xin She)
