Xiao Qinglong Decoction comes from Zhang Zhongjing's "Treatise on Febrile Diseases". The drug composition is: Ephedra? Guizhi Paeoniae? Dried ginger and asarum? Schisandra licorice and pinellia? One bucket of water, first boil ephedra and reduce it to two liters, remove the foam, add all the medicines, boil three liters, remove the dross, and drink one liter warmly.

Classical prescriptions have the characteristics of using small amounts of medicinal herbs, with simple and powerful effects. The Qingfei Paidu Decoction for the treatment of new coronavirus pneumonia has been released with 22 medicinal herbs, which gives people a feeling of complicated medication. It should be the latest prescription. , how effective it is, should be clinically verified. It’s easy to get everything, but hard to find the one effect (recipe). It’s honest and trustworthy!

The function of Xiaoqinglong Decoction is to relieve external cold, warm the lungs and transform fluids. It is mainly used to treat external cold and internal fluids. It is quite consistent with the symptoms of COVID-19. Cheng Wuji said in "Shang Han Ming Theory": Ephedra is sweet in taste and warm in nature. Guizhi tastes pungent and hot, while licorice tastes sweet and flat. Sweet and pungent is yang, and it is supplemented with ephedra to express it. The two are ministers. Peony tastes sour and slightly cold, while Schisandra chinensis has a sour and warm taste. The two are used as supplements. Dried ginger, asarum, and pinellia are the three ingredients. The formula is rigorous and the procedures are clear, so that the cup can be healed as effectively as a drum.

The classic prescriptions have been used since Zhongjing. After thousands of years of clinical verification, the clinical efficacy is obvious. There are methods, prescriptions and medicines. On the contrary, many times the prescriptions have prescriptions but no medicine, or medicines but no prescription, and the efficacy is doubtful. , Zhu Ju's "Puji Fang" contains more than 10,000 prescriptions, which is the degradation of prescriptions. Nowadays, people just pick up a recipe and add medicine according to the symptoms without any rules. It is not Han Xin's army. The more the better. We need to know that there is a den of soldiers. How can we defeat the enemy in battle and how can we cure diseases clinically?
