The pivotal targets of puerarin to treat COVID‐19 were identified and included the epidermal growth factor receptor (EGFR), tumour necrosis factor (TNF), tumour protein p53 (TP53), caspase 3 (CASP3), RELA proto‐oncogene (RELA), Fos proto‐oncogene (FOS), caspase 8 (CASP8), prostaglandin‐endoperoxide synthase 2 (PTGS2), interleukin 2 (IL2), protein kinase CB (PRKCB), B cell lymphoma/leukaemia gene‐2 (BCL2), protein kinase CA (PRKCA), nitric oxide synthase 3 (NOS3) and peroxisome proliferator–activated receptor gamma (PPARG). Here, BCL2 is linked to COVID-19.
