ABSTRACT

Coronavirus disease-2019 (COVID-19) belongs to the epidemic diseases of traditional Chinese medicine (TCM), which is infected by the air with disease and the initial stage of the disease is in upper energizer. TCM holds that the nose is the orifice of the lung and the gateway of the breath. WU Shang-xian, the famous external doctor in Qing dynasty, discussed in Liyue Pianwen that "for the disease in upper energizer, the most effective method is to use the medicine powder via nasal administration and sneeze to disperse". For thousands of years, ancient Chinese medical practitioners had explored and developed the TCM nasal administration method in the struggle against epidemics. Qingkailing is the basic formula for heat-clearing and detoxifying, and researches have clarified its therapeutic effect on upper respiratory tract infections. Therefore, based on TCM nasal administration, this article took Qingkailing as an example to study the feasibility of its nasal preparations for the treatment of COVID-19. On the one hand, it is helpful for the rapid development of Qingkailing nasal preparations for COVID-19. On the other hand, it can broaden the new thinking of TCM in treating epidemic diseases, and give full play to the advantages of TCM in treating epidemic diseases.
