Background

Inflammation is a defense-based response of the body to various inflammatory factors, clinically characterized by redness, swelling, heat, pain, and is the response of inflammatory factors to the local injury of living tissues with vascular systems. The pathological process is generally divided into early capillary hyperfiltration, exudation of vascular contents, edema, and late connective tissue hyperplasia and granuloma formation; pain refers to the somatic sensation associated with tissue injury and potential tissue damage, when tissue is inflamed or damaged, the injured site releases pain-causing substances such as bradykinin, histamine, 5-hydroxytryptamine, prostaglandins, etc., which stimulate receptors of afferent nerve endings to produce pain sensation. Pain and inflammatory response indicate tissue damage to the body, and inflammation and pain can cause health hazards to the body.

Inflammation and pain are common clinical symptoms, and are treated by using anti-inflammatory analgesic drugs clinically, and the current anti-inflammatory analgesic drug treatment usually uses non-steroidal drugs, which interfere with the synthesis of prostaglandins (prostaglandins) by inhibiting Cyclooxygenase (COX) which is necessary for the synthesis of the prostaglandins, so as to achieve the anti-inflammatory analgesic effect. However, in clinical use, chemical drugs such as non-steroidal anti-inflammatory drugs with anti-inflammatory and analgesic effects often cause a series of adverse drug reactions such as gastrointestinal reactions and allergic reactions. Clinical application and pharmacological research show that the traditional Chinese medicine Zhuang nationality medicine has the advantages of obvious action effect and small adverse reaction in the aspect of anti-inflammatory and analgesic effects, has high efficiency and small adverse reaction in development and application of the traditional Chinese medicine Zhuang nationality medicine, and has very important significance and wide application prospect.
