Quercetin for COVID-19
23rd treatment shown to reduce risk in July 2021
*, now with p = 0.0031 from 11 studies.
No treatment is 100% effective. Protocols combine treatments. * >10% efficacy, ≥3 studies.
4,400+ studies for 79 treatments.
In Silico analysis showing that curcumin and quercetin may be beneficial for COVID-19 by binding to the main protease (Mpro), spike protein, and ACE2 receptor. Both compounds had suitable ADME properties and minimal predicted toxicity.
58 preclinical studies support the efficacy of quercetin for COVID-19:
In Silico studies predict inhibition of SARS-CoV-2, or minimization of side effects, with quercetin or metabolites via binding to the spikeA,1,2,14,16,17,22,30,31,33,34,51,52, MproB,1,3,5,7,9,10,12,15,16,22,26,28-30,34,35,37,52,53, RNA-dependent RNA polymeraseC,1,24, PLproD,29,37, ACE2E,14,15,20,29,33,52, TMPRSS2F,14, helicaseG,21,26, endoribonucleaseH,31, cathepsin LI,18, Wnt-3J,14, FZDK,14, LRP6L,14, ezrinM,32, ADRPN,30, NRP1O,33, EP300P,8, PTGS2Q,15, HSP90AA1R,8,15, matrix metalloproteinase 9S,23, IL-6T,13,27, IL-10U,13, VEGFAV,27, and RELAW,27 proteins.

In-silico Approach for Predicting the Inhibitory Effect of Home In-silico Approach for Predicting the Inhibitory Effect of Home Remedies on Severe Acute Respiratory Syndrome Coronavirus-2 Remedies on Severe Acute Respiratory Syndrome Coronavirus-2
Shankar Thapa, Mahalakshmi Suresha Biradar, Janmajoy Banerjee, Dipanjan Karati
Severe Acute Respiratory Syndrome Coronavirus-2 is an infectious disease caused by coronavirus and spreads through infected droplets inhalation. For the past 3 years, COVID-19 has become a global threat. Vaccinations are currently available and have FDA approval. During the recent pandemic, people adopted a psychological belief that home remedies (turmeric, ginger, garlic, and coriander) can prevent COVID-19. This research aimed to predict the covid-19 inhibitory activities by home remedies through an in-silico approach. The 24 bioactive constituents of four home remedies plants were
