Therapeutic opportunities of edible antiviral plants for COVID-19

Molecular and Cellular Biochemistry, 2021

The pandemic of Serious Acute Respiratory Syndrome Corona Virus-2 (SARS-CoV-2) that produces corona virus disease (COVID-19) has challenged the entire mankind by rapidly spreading globally in 210 countries affecting over 25 million people and about 1 million deaths worldwide. It continues to spread, afflicting the health system globally. So far there is no remedy for the ailment and the available antiviral regimens have been unsatisfactory for the clinical outcomes and the mode of treatment has been mainly supportive for the prevention of COVID-19-induced morbidity and mortality. From the time immortal the traditional plant-based ethno-medicines have provided the leads for the treatment of infectious diseases. Phytopharmaceuticals have provided potential and less toxic antiviral drugs as compared to conventional modern therapeutics which are associated with severe toxicities. The ethnopharmacological knowledge about plants has provided food supplements and nutraceuticals as a promise for prevention and treatment of the current pandemic. In this review article, we have attempted to comprehend the information about the edible medicinal plant materials with potential antiviral activity specifically against RNA virus which additionally possess property to improve immunity along with external and internal respiration and exhibit anti-inflammatory properties for the prevention and treatment of the disease. This will open an arena for the development of novel nutraceutical herbal formulations as an alternative therapy that can be used for the prevention and treatment of COVID-19.

Antiviral potential of frequently used plants in herbal formulations as immunity enhancers against SARS-CoV-2

Annals of phytomedicine, 2022

A severe acute respiratory syndrome (SARS) is an extraordinary type of communicable infection that is caused by SARS-coronavirus. Since last two years, the entire world is fighting with this highly infectious disease and researchers are devoting all their labours to develop vaccines and few vaccines with remarkable efficacies have been developed. However, the great rate of mutations in SARS-CoV-2 annoying everyone. Though, the scientific communities are doing their best towards neutralizing the impact of infection yet the best way to combat this virus and future similar infections is to boost our immune system in a natural way. In this review, the prospective of widespread and easily available plants have been discussed as immunity enhancers to combat COVID-19 and other viruses.

Aromatic Herbs, Medicinal Plant-Derived Essential Oils, and Phytochemical Extracts as Potential Therapies for Coronaviruses: Future Perspectives

Plants

After its recent discovery in patients with serious pneumonia in Wuhan (China), the 2019 novel coronavirus (2019-nCoV), named also Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), has spread quickly. Unfortunately, no drug or vaccine for treating human this coronavirus infection is available yet. Numerous options for controlling or preventing emerging 2019-nCoV infections may be predicted, including vaccines, interferon therapies, and small-molecule drugs. However, new interventions are likely to require months to years to develop. In addition, most of the existing antiviral treatments frequently lead to the development of viral resistance combined with the problem of side effects, viral re-emergence, and viral dormancy. The pharmaceutical industry is progressively targeting phytochemical extracts, medicinal plants, and aromatic herbs with the aim of identifying lead compounds, focusing principally on appropriate alternative antiviral drugs. Spices, herbal medicines, es...

Role of herbal medicine for controlling coronavirus (SARS-CoV-2) disease (COVID-19)

This review paper highlights the use of herbal medicine in the management of the coronavirus disease COVID-19 (SARS-CoV-2) pandemic, which has caused a worldwide outbreak of respiratory illness. This is caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), which is zoonotic infecting both animal and human. Vaccines are the most promising solution to mitigate new viral strains. The Indian system of holistic medicine known as "Ayurveda" plays an important role in controling the viral disease SARS-CoV-2 and other health disorders. Dietary therapy and herbal medicine could be a complementary preventive therapy for COVID-19 (SARS-CoV-2). Plants have been used as a expression systems for the production of diagnostic reagents and pharmaceutical proteins often described as "molecular farming. On the basis of literature survy presented, some of the plant secondary metabolites that showed prominent antiviral activity against coronaviruses SARS-CoV-2 through impeding the main machinery used in their pathogenesis and replication cycle. The in vitro, in vivo, and in silico investigations revealed numerous plant-derived compounds with promising anti-SARS-CoV and anti-SARS CoV-2 activity. Therefore, this review gathered all antiviral plants in a single platform to facilitate the laboratory-based research for the development of novel drug/molecular therapeutics to overcome the SARS-CoV-2 and future pandemic situations. Further detailed clinical trial experiments should be conducted for the scientific validation.

Phytogenic Products and Phytochemicals as a Candidate Strategy to Improve Tolerance to Coronavirus

Frontiers in Veterinary Science, 2020

Coronaviruses are the causative agents of many infectious diseases in human and animals. These included severe acute respiratory syndrome (SARS), avian infectious bronchitis (IBV) in poultry, Middle East respiratory syndrome (MERS), and coronavirus disease 2019 (COVID-19) in humans. These results had considerable death burdens and negative influences on social-economic life. Since the appearance of the outbreak of the COVID-19 pandemic, continuous investigations have been carried out by researchers to find active compounds, mainly from plants, as natural sources, that could inhibit or stop the proliferation of the causative agent of COVID-19 (SARS-CoV-2). The most common symptoms caused by infections with COVID-19 can include cough, fever, and sore throat. Nevertheless, there is a shortage of active antiviral compounds for treating different strains of coronavirus. Herbal medicine is a class of medication that originates from nature and is aimed at decreasing the use of preservatives, excipients, or other additives and, consequently, lesser side effects. The rapid spread of COVID-19 infection besides the lack of knowledge about any treatments and the growing concern of the public from the virus directed us toward writing this review article in an aim to provide alternatives to the allopathic medicine use. There is a wealth of chemical diversity in the naturally existing compounds, including their antiviral activities, which may encourage their utilization as therapeutics against viral infections, including coronaviruses. The majority of publications on the herbal remedies of coronavirus, MERS, or SARS focused primarily on the use of polar compounds. These substances displayed encouraging inhibitory influences on coronavirus in humans. These include psoralidin, scutellarein, silvestrol, tryptanthrin, caffeic acid, quercetin, myricetin, saikosaponin B2, griffithsin (lectins), and isobavachalcone. Some other agents like lycorine may be useful, Attia et al. Phytogenic as Promising Agents for Coronavirus if the antiviral activity is obtained by concentrations below the toxic plasma levels. According to the available literatures, the most promising inhibitors of coronaviruses are polyphenolic compounds, which are small molecules with conjugated fused ring structures.

Phytochemicals as Potential Antiviral Agents in SARS-COV-2 Therapy: An Update

QuĂ­mica Nova, 2021

In December 2019, the World Health Organization officially announced the discovery and fast spread of the new coronavirus disease (COVID-19), which is caused by the SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2), discovered in Wuhan, China. Since the beginning of the pandemic, there has been a global search for the discovery of antiviral candidates capable of treating the infection caused by SARS-CoV-2. However, none of them has shown proved efficacy and low toxicity for an effective dose. In view of this, research with plants based in natural products has been highlighted by the low toxicity of its metabolites and reduced side effects, since plants have been used for millennia in the treatment of various diseases. In this review, we highlight some plant species and plant metabolites belonging to the structural class of phenolic, alkaloids and terpenes with promising antiviral potential against coronavirus that could be explored as potential candidates for drug prototy...
