Antiviral Plant Extracts

Herbal therapy has been an important part of health and wellness for hundreds of years. The renewed interest in medicinal plants has focused on herbal cures among indigenous populations around the world. Recent surveys have indicated that worldwide people now make more visits to healthcare professionals who specialize in alternative medicine than to doctors who practice conventional medicine. It is hoped that extracts from herbs will add new medicinal plants to the world’s pharmacopoeia before they are lost forever that too particularly against viral infection. Based on the ethnobotanical data and the information collected from Siddha/Ayurvedic practitioners of India, extracts obtained from Boerhavia diffusa, Eclipta alba and Phyllanthus amarus will be having great potential in curing various viral infections

A systematic review on COVID-19 pandemic with special emphasis on curative potentials of Nigeria based medicinal plants

Despite the frightening mortality rate associated with COVID-19, there is no known approved drug to effectively combat the pandemic. COVID-19 clinical manifestations include fever, fatigue, cough, shortness of breath, and other complications. At present, there is no known effective treatment or vaccine that can mitigate/inhibit SARS-CoV-2. Available clinical intervention for COVID-19 is only palliative and limited to support. Thus, there is an exigent need for effective and non-invasive treatment. This article evaluates the possible mechanism of actions of SARS-CoV-2 and present Nigeria based medicinal plants which have pharmacological and biological activities that can mitigate the hallmarks of the pathogenesis of COVID-19. SARS-CoV-2 mode of actions includes hyper-inflammation characterized by a severe and fatal hyper-cytokinaemia with multi-organ failure; immunosuppression; reduction of angiotensin-converting enzyme 2 (ACE2) to enhance pulmonary vascular permeability causing damage to the alveoli; and further activated by open reading frame (ORF)3a, ORF3b, and ORF7a via c-Jun N- terminal kinase (JNK) pathway which induces lung damage. These mechanisms of action of SARS-CoV-2 can be mitigated by a combination therapy of medicinal herbs based on their pharmacological activities. Since the clinical manifestations of COVID-19 are multifactorial with co-morbidities, we strongly recommend the use of combined therapy such that two or more herbs with specific therapeutic actions are administered to combat the mediators of the disease.publishedVersionFil: Oladele, Johnson O.

A Brief Overview of Potential Treatments for Viral Diseases Using Natural Plant Compounds: The Case of SARS-Cov

Review paper, jointly written by experts from Universiti Putra Malaysia, Taras Shevchenko National University of Kyiv (Ukraine), Kermanshah University of Medical Sciences (Iran), Federal University of Maranhão (Brazil), Central University of Punjab (India), Federal Scientific Center of the East Asia Terrestrial Biodiversity (Russia), De Montfort University (UK), University of Orléans (France) open access articleThe COVID-19 pandemic, as well as the more general global increase in viral diseases, has led researchers to look to the plant kingdom as a potential source for antiviral compounds. Since ancient times, herbal medicines have been extensively applied in the treatment and prevention of various infectious diseases in different traditional systems. The purpose of this review is to highlight the potential antiviral activity of plant compounds as effective and reliable agents against viral infections, especially by viruses from the coronavirus group. Various antiviral mechanisms shown by crude plant extracts and plant-derived bioactive compounds are discussed. The understanding of the action mechanisms of complex plant extract and isolated plant-derived compounds will help pave the way towards the combat of this life-threatening disease. Further, molecular docking studies, in silico analyses of extracted compounds, and future prospects are included. The in vitro production of antiviral chemical compounds from plants using molecular pharming is also considered. Notably, hairy root cultures represent a promising and sustainable way to obtain a range of biologically active compounds that may be applied in the development of novel antiviral agents

Identification of therapeutic targets for controlling COVID-19 pandemic by traditional system of Ayurvedic medicines: A systematic review

11-24COVID-19 is a severe respiratory disorder caused by the SARS COV-2 virus that involves limited innate immunity. Numerous publications have suggested that plants/minerals used in the traditional system of Ayurveda, has revealed much about the biology of COVID-19. One theory is that combination of anti viral, anti inflammatory, agents activating immune cells, herbs and metals may be helpful for severe acute respiratory syndrome coronavirus infection. Anti-viral drugs used for COVID-19 are those which block RNA synthesis and virus invasion, and bind to receptor proteins on the surface of cells, cell cycle protein, and physiological and pathological processes inhibitor. Anti-inflammatory drugs used for COVID-19 are those which controls transcription of DNA, cytokine production, break down the basement membrane, regulate outer mitochondrial membrane permeability, controlling the host cell life, stimulates activated B-cell and T-cell proliferation, virus dissemination, a slowdown of cell metabolism or secretion of cytokines. Drugs which is having role in the innate immunity, inhibits ROS, enhances cell lifespan, activates macrophages, physiological effects on cells activates the Lung resident immune cells. The focus of this review is to elucidate the Ayurvedic pharmacological properties with their therapeutic targets
