Some patients with corona virus disease-2019 (COVID-19) experienced a severe exacerbation of the disease due to the occurrence of inflammatory storm during the development of the disease. They are complicated with acute respiratory distress, multiple organ dysfunction syndrome and other serious complications, with a poor prognosis and a high mortality. For the inflammation storm, western medicine mostly adopts glucocorticoids, nutritional support, artificial ventilation assistance and other measures at present. The development of artificial liver, blood purification therapy, extracorporeal membrane oxygenation and other technologies have also reduced the mortality of patients to some extent. However, due to the high requirements for equipment, the measures have not yet been widely carried out. From the perspective of traditional Chinese medicine(TCM), the basic pathogenesis of COVID-19 is epidemic toxin invasion, lung and spleen being affected by pathogens, damaging vital Qi, and pathological properties involving dampness, heat, poison, stasis and deficiency. At the stage of inflammation storm, the pathogens are abundant, while the vital Qi is deficient， and the pathogens occlude lung, and disturb the heart and mind, and blood stasis and toxicity are combined with Qi-Yin deficiency. In severe cases, even both Yin and Yang exhaustion occurs. At present, a number of studies have shown that a variety of Chinese herbal medicines have multi-target immunomodulatory effect on viral pneumonia and cytokine storm. TCM participates in whole process of the occurrence and development of inflammation storm, mainly eliminating pathogens in early stage, controlling inflammation and blocking occurrence of inflammation storm， eliminating pathogens and strengthening the body resistance to eliminate the pathological products of the inflammation storm, and promoting the dissipation and absorption of inflammation in the middle stage， and saving lives in late stage by benefiting Qi and relieving depletion, and restoring Yang and rescuing from collapse. On the basis of pathophysiological mechanism of COVID-19 inflammation storm and the theory of TCM syndrome differentiation and treatment, this paper summarized the pharmacological studies on intervention on inflammatory storm with relevant Chinese herbal medicine, Chinese medicine prescriptions and Chinese medicine preparations, and discussed the intervention measures of TCM in different development stages of inflammatory storm, in expectation of providing the guidance for clinical treatment.
