Review Covid-19 (Sars-Cov-2) and Medicinal Plants – Literature

Abstract

In December 2019, a new coronavirus originating from the city of Wuhan in China started an epidemic that brought many countries into chaos and despair. SARS-CoV-2, as identified, gave rise to the severe acute respiratory syndrome called COVID-19. Its transmission happens through droplets of saliva, hand or contaminated surfaces. Since its discovery, COVID-19 has led many to death, therefore, researchers from around the world have joined efforts to develop strategies to contain the virus. In this race, drugs such as Chloroquine and Hydroxychloroquine have become possible options for showing an antiviral effect, however, studies contest their efficiency, generating uncertainties. Therefore, other alternatives have been investigated in this context, and the study of medicinal plants has been the target of research for the treatment of COVID-19 in search of bioactive natural products that can exert an antiviral action. The study aimed to analyze the published literature on COVID-19 (SARS-CoV-2) and its relationship with medicinal plants. Bibliographical survey. So far, no specific treatment against the disease has been found, only supportive, with drugs that aim to improve the individual's immune system and ensure that the virus does not replicate, for example, there are options such as chloroquine, hydroxychloroquine, remdesivir and convalescent plasma. On the other hand, studies have revealed that medicinal plants such as garlic, among others, showed efficiency in modulating proteins with a view to preventing viral replication and improving immunity against COVID-19. So far, there are no drugs that are completely safe and have been shown to have activity against the new coronavirus (SARS-CoV-2). However, medicinal plants can contribute to the development of specific therapies against SARS-CoV-2 in a safe and effective way.
