Wang et al. [12] discussed the targets and signaling pathways of Maxing Shigan decoction for treating pneumonia through systems pharmacology and found that the possible targets were IL-6, TNF, MAPK8, etc. Xia et al. found that Akt1 was a potential target of Lianhua Qingwen to treat and prevent COVID-19 using network pharmacology and molecular docking analyses [13]. Here, TNF is linked to COVID-19.
