IntroductionNatural bioactive compounds with pharmaceutical potential are derived from plants. However, these compounds are widely recognized as secondary plant metabolites, such as terpenoids, lignans, flavonoids, tannins, and alkaloids, which have various biological activities, including antibacterial, antiviral, and functional properties similar to the activity of drugs. 1,2 Several medicinal metabolites obtained from plants can hinder virus reproduction or impede cellular infection, hindering the transmission of the virus. In the current scenario, respiratory tract infections have led to significant morbidity and mortality rates worldwide. Several viral agents have the potential to trigger respiratory illnesses, leading to widespread outbreaks and, in specific cases, global pandemics. These include influenza viruses and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). 3
