More and more clinical evidence shows that patients with Coronavirus Disease 2019 (COVID-19) died due to severe complications such as acute respiratory distress syndrome and multiple organ failure due to the aggravation of the disease in the later period, and the main cause of the aggravation is "cytokine storm". There is no specific drug for the treatment of severe COVID-19 patients. Although western medicine can improve some symptoms, it leaves a large sequela, while traditional Chinese medicine plays an important role in this outbreak. In this paper, based on the clinical reported cytokines storm-related indicators, the traditional Chinese medicine systems pharmacology database and analysis platform (TCMSP) was used to mine and screen the traditional Chinese medicines acting on these cytokines based on the theory of "damp toxin invading the lung". It was found that 19 cytokines, including interleukin-6 (IL-6), tumor necrosis factor α (TNFα), granulocyte-macrophage colony stimulating factor (GM-CSF) and so on, were closely related to COVID-19, and 22 traditional Chinese medicines such as Ephedrae Herba, Glycyrrhizae Radix Et Rhizoma and Lonicerae Japonicae Flos acted on these cytokines, so as to provide certain reference for the reasonable choice of prescription and addition or modification of drugs for COVID-19 patients in the middle and late stage of Chinese medicine clinical treatment.
