In recent COVID-19 target discovery investigations, some novel targets of high drug repurposing potential have been revealed by focusing on the COVID-19 interacting host proteins and infected host cell proteomics [2, 3] . In the COVID-19 therapeutics fields, traditional medicines have also been repurposed for COVID-19 treatment as recommended by the National Health Commission of China (NHCC) [4] , albeit without clear mechanistic knowledge and little clinical validation. The first multicenter, prospective, randomized controlled trial of a repurposed traditional medicine against COVID-19 has just been reported [5] . Questions arise regarding their scientific basis and, if founded, how the therapeutic mechanisms of this and other NHCC-recommended repurposed traditional medicines might differ from the targets of the COVID-19 therapeutics. Mechanistic clues of these NHCC-recommended traditional medicines have been investigated by a multi-omics analysis of the targets of potent (≤1M) activities (henceforth named potent targets), particularly with respect to the clinical gene expression profiles of several inflammation-related diseases [6] . That analysis has indicated that the potent modulations of several inflammation-regulatory targets are possible mechanisms against COVID-19. It has also exposed the dual inflammation inhibitory (pro) and promoting (con) effects of these traditional medicines. The estimated percentages of the patients with the pro and con effects are 16%-32% and 7%-17% respectively, with the pro effect patients outnumbering the con effect patients by up to 25%. These indications are consistent with the reported clinical observations. A multicenter, prospective, randomized controlled trial of the repurposed J o u r n a l P r e -p r o o f this capsule outnumbers the estimated con effect patients by 25% [6] . Moreover, the estimated pro-inflammatory effects in 7%-17% patients are consistent with the reported pneumonitis and lung injury in the patients of interstitial lung diseases treated by kampo formulations (references in [6] ).
