“Daochi San, a classic pediatric formula originating from Qian Yi's "Direct Formula for Pediatric Medicine Syndrome" in the Song Dynasty, has been widely used in traditional Chinese medicine clinical practice through the inheritance and development of medical practitioners throughout history. Through the systematic organization of ancient and modern literature, researchers have delved into the composition, processing, manufacturing methods, and applications of Daochi San. Research has found that the medicinal base of Daochi San is clear, including four medicinal herbs: Dihuang, Mutong, Licorice, and Bamboo Leaf. This prescription has the effects of clearing the heart and nourishing yin, promoting diuresis and promoting diuresis. It has significant therapeutic effects on symptoms such as chest restlessness, thirst, red face, mouth and tongue sores, and painful urination caused by excessive heat in the heart meridian. Modern research has shown that Daochi San can also be used to treat oral ulcers, herpetic stomatitis, urinary tract infections, herpes zoster and other diseases, providing a new option for traditional Chinese medicine treatment of these diseases. These research results not only enrich the experience of clinical medication in traditional Chinese medicine, but also provide important reference for the later development and research of Daochi San.”
