The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the coronavirus disease (COVID-19) pandemic, which has led scientists all over the world to push for the identification of novel therapies for COVID-19. The lack of a vaccine and specific treatment has led to a surge of novel therapies and their publicity in recent times. Under these unprecedented circumstances, a myriad of drugs used for other diseases is being evaluated and repositioned to treat COVID-19 (example- Remdesivir, Baricitinib). While multiple trials for potential drugs and vaccines are ongoing, and there are many unproven remedies with little or no supporting evidence. Presently, discussions are revolving around the use of multivitamins (Vitamin, C, D, A), minerals (selenium, zinc), probiotics, flavonoids, polyphenols, and herbal remedies (curcumin, artemisinin, herbal drinks). Our review delves further into the details of some of these controversial therapies for COVID-19.
