Natural compounds from medicinal plants against COVID-19

The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), known to cause the coronavirus disease 2019 (COVID-19), was declared a pandemic in early 2020. During the past time, several infections control methods have been developed. Nevertheless, all of them have certain limitations: uncertainty in duration, limited efficacy of vaccines, and lack of effective drugs for COVID-19 treatment. So, the issue of creating drugs for symptomatic and etiotropic therapy is still relevant. This review summarizes the current knowledge of using natural compounds as anti-SARS-CoV-2 agents by analysing the results of in vitro studies and completed clinical trials (CTs). Also, this work highlighted the most active molecules and discussed the possibility of using some compounds in clinical practice.
