COVID-19 is an emerging, rapidly evolving pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Due to its distinctive features in etiology, epidemiology and pathology, this infectious disease poses considerable diagnostic and therapeutic challenge [1]. Patients with COVID-19 mainly receive supportive care and symptom management, since there is no specific antiviral treatment yet for COVID-19. In addition to the principles of early quarantine, early detection, and early treatment [2], the early inclusion of traditional Chinese medicine (TCM) to the Chinese protocol, i.e., the integration of TCM and Western medicine, also contributed to the rapid containment of COVID-19 in China. TCM not only has a long history against the epidemic diseases but also plays a significant role in combating COVID-19.
