The continued spread of the 2019 novel coronavirus (2019-nCoV) has prompted global concern. The formal name given to 2019-nCoV by the World Health Organization is COVID-19, while the International Committee on Taxonomy has named it severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Due to this viral attack, nations around the world have issued lockdown restrictions. Presently, there is no effective way to control the spread of 2019-nCoV, except through social distancing and hygienic activities. World-class scientists and researchers are trying to develop vaccines and medicines that will cure this deadly viral disease and control its spread. Our aim in presenting this article is to provide an easy therapeutic approach that effectively combats deadly viral diseases, such as COVID-19, with minimal intervention and effort. Different Ayurvedic therapeutic agents (Curcuma longa L, green tea, and Piper nigrum) inhibit the entry of viruses in the host cell and the transmission of pathogens, while improving immunity. Curcumin and piperine (1-piperoylpiperidine) interact with each other and form a π–π intermolecular complex that enhances the bioavailability of curcumin by inhibition of glucuronidation of curcumin in the liver. Two molecules, curcumin and catechin, bind directly to the receptor-binding domain of the S-protein and the angiotensin-converting enzyme 2 receptor of the host cell, by which these molecules inhibit the entry of viruses in the host cell. As a result, the animal host will survive the infection.
