Similarly, several randomized clinical trials involving patients with COVID-19 have also revealed multiple treatment benefits for quercetin adjuvant therapy, including faster negativization of the SARS-CoV-2, early amelioration of the acute symptoms, reduction in the serum levels of inflammatory markers such as CRP, LDH, ferritin, and alkaline phosphatase (Kamel et al., 2020; Di Pierro et al., 2021a; Di Pierro et al., 2021b; Onal et al., 2021; Shohan et al., 2022). The gene discussed is CRP; the disease is COVID-19.
