The unpredictable global pandemic faced by the world in 2019, recognised as COVID-19, originated by SARS-CoV-2 virus has threatened human wellbeing and public safety across the entire world, by affecting more than six hundred million people as well as more than 6.7 million global deaths, as of January, 2023. This worldwide epidemic drew the attention towards the necessity of effectual defensive and curative processes in order to extend anti-viral treatment against the deadly virus. Many phytochemical constituents have been recognized to have a variety of curative characteristics against various viral diseases and thus it is becoming the need of the hour for the research community to attempt for anti-viral drugs from phytochemicals that can strengthen our immune system in order to combat COVID-19. Through this review article, we have attempted to analyse the prospective anti-viral implications of few phytochemicals, viz., quercetin, thymoquinone, caffeic acid, rosmarinic acid, ursolic acid, vanillin, thymol, ellagic acid etc., against the SARS-CoV-2.
