The importance of medicinal herbs and the effective substances they contain in facing the emerging corona virus (COVID-19) and their uses in our daily life

Mohamed Younes A. Hassan, Idress Hamad Attitalla, Hossam B. Bahnasy


Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory coronavirus-2 (SARS-CoV-2), is an extremely infectious disease and has already infected nearly seven million people and caused more than 402,852 deaths in the world. Based on our current knowledge of this virus and in the absence of a vaccine, this article is an attempt to propose ways to prevent treat and control the COVID-19 virus, using medicinal plants such as Eucalyptus globulus Labill, Cymbopogon citratus, Mentha, citrus, Zingiber officinale, Syzygium aromaticum that have been shown to be effective. Ginger (Zingiber officinale Roscoe) is a common and widely used spice. It is rich in various chemical constituents, including phenolic compounds, terpenes, polysaccharides, lipids, organic acids, and raw fibers. The health benefits of ginger are mainly attributed to its phenolic compounds, such as gingerols and shogaols. Accumulated investigations have demonstrated that ginger possesses multiple biological activities, including antioxidant, anti-inflammatory, antimicrobial, anticancer, neuroprotective, and cardiovascular protective, respiratory protective, ant obesity, antidiabetic, ant nausea, and antiemetic activities. In this review, we summarize current knowledge about the bioactive compounds and bioactivities of ginger, and the mechanisms of action are discussed. We hope that this updated review paper will attract more attention to ginger and its further applications, including its potential to be developed into functional foods or nutraceuticals for the prevention and management of chronic diseases. An effective vaccine to prevent the SARS-CoV-2 causing COVID-19 is yet to be approved. Further, there is no drug that is specific to treat COVID-19. In line with the proposed use of chloroquine, Nigella sativa (black seed) could be considered as a natural substitute that contains a number of bioactive components such as thymoquinone, dithymoquinone, thymohydroquinone, and nigellimine. Among the general and important benefits of those herbs used in this paper and in this research are the merging of herbs together, obtaining general benefits for the human body, strengthening the immune system, improving the properties of the digestive system and blood circulation, general tonics, antioxidants and some other benefits that benefit the person in the face of any disease or bacterial infection or Viral infection.
