Action principle of surgical plaster of traditional Chinese medicine

Generally, a plaster consists of two parts: plaster and medicine. The plaster part is relatively simple, and the components are relatively fixed, while the medicine part is relatively complex, which often varies from person to person, from time to time and from place to place due to illness. The plaster in the plaster is mainly composed of Youdan, which is called plaster matrix, and both of them have certain medical functions in clinic. Oil moistens the skin so that Dan medicine does not dry, and it has the function of detoxifying and killing insects to maintain lasting efficacy. Dan has the functions of killing insects, relieving fever, removing phlegm, removing stasis, promoting granulation and so on. The prescription of plaster is based on the principle of meridian tropism of general Chinese medicine, and uses the efficacy of drugs to coordinate with each other to form a compound of many drugs, so as to give full play to the good effects of drugs. Plasters are generally used in a wide range of drugs, forming a large compound to adapt to complex pathological changes. Because plasters are mostly used for thin patches on the muscle surface, drugs with thick smell are generally taken, and the drugs are led to lead the group of drugs, which can lead to stagnation and direct to the disease. Therefore, it can penetrate into the skin to produce anti-inflammatory, analgesic, putrefaction, granulation, convergence, blood circulation promoting, blood stasis removing, meridian dredging, bone opening, wind expelling and cold dispelling.

Plasters are generally divided into two parts, one is to be applied to the affected part when treating carbuncle, furuncle, furuncle, ulcer and other diseases, and the other is to be applied to the meridian points of the human body when treating diseases such as meridians. The plaster attached to the body surface stimulates nerve endings, dilates blood vessels through reflection, promotes local blood circulation, improves the nutrition of surrounding tissues, and achieves the functions of detumescence and anti-inflammation. At the same time, drugs penetrate through the skin at acupoints and reach subcutaneous tissues, resulting in the relative advantage of drug concentration locally, thus playing a strong pharmacological role, and having local effects such as anti-corrosion, anti-inflammatory and pain relief for the treatment of trauma, skin diseases and mucosal lesions. In addition, some drugs with strong stimulation can regulate the body function, promote antibody formation and improve human immunity through nerve reflex. At the same time, after the drug penetrates the skin and mucosa, it enters the systemic circulation through blood vessels or lymphatic vessels, which can produce systemic drug effects and achieve the purpose of treating diseases.
