Discovering the potential of natural remedies in the post COVID-19 complications based on in silico techniques

The first incidence of corona virus was reported in China in December of 2019, and the virus quickly spread over the world, eventually being designated a pandemic in March of 2020. It has had a disastrous impact on the global healthcare system. Virus has claimed the lives of 5,298,933 people through December 2021. As a result of the pandemic, there was a boost of research into diagnostic and therapeutic methods to infection. Gradually, the world has discovered new vaccine candidates and medicinal repurposing strategies that have a significant influence on mortality, by which there has been a drop-in death rates over the world since July, 2021. Many patients, particularly those who have been hospitalized due to a viral infection, experience complications beyond discharge that have a significant influence on their lives. Post COVID-19 complications are problems that last longer than 3-4 weeks following a viral infection. There is currently no specific treatment accessible for post COVID-19 problems because whatever medications are available or repurposed are limited to disease prophylaxis and therapeutics. As a result, we're looking for a remedy employing natural substances using the In-Silico technique (molecular docking) and recent research from reputable journals. Allicin, Berberine, Epigallocatechin, Rosmarinic acid and Withaferin-A were docked against ACE (PDB ID: 1O8A), IL-6 (PDB ID: 1ALU), NADPH Oxidase (PDB ID: 2CDU) and TNF- α (PDB ID: 2AZ5) using Autodock.
