Background: World Health Organization states that antibacterial/antimicrobial resistance (AMR) can threaten the effective prevention and treatment of an ever-increasing range of infections caused by bacteria, parasites, viruses, and fungi. Objective: This review aims to discuss the plants and their derivatives having anti-corona virus/ viral activity. Methods: For the preparation of this review article, all the relevant information was gathered from accessible and inaccessible resources (Web, Books, Thesis, etc.). Results: It has been accepted worldwide that the uses of herbal products provide stronger immunity which helps to fight against these microbial species. SARSCoV2 virus is now a pandemic, affecting many countries around the globe. This long series of herbal species may interfere with the target-specific proteins named S Protein, S protein- ACE-2 interaction, Helicase protein, N Protein, 3CLpr, PL pro to prevent the viral replication in the host. Traditional herbal medicine not only inhibits the virus attachment to the host body but also prevents replication and boosts up the host immune system. Natural remedies reduce the viral load and, in such conditions, the immunity becomes stronger, and so the patient can recover soon. Conclusion: The herbs-natural compounds with antiviral activity can effectively inhibit/blockade the CoV-host protein. Herbal medicine having immune boost-up property will play a major role as an anti-corona virus drug.
