The disease has spread globally with more than 7.73 million confirmed cases and .43 million deaths as of June 14, 2020 [1]. Despite worldwide efforts to contain it, the pandemic is continuing to spread for want of a clinically-proven prophylaxis and therapeutic strategy. The dimensions of pandemic require an urgent harnessing of all knowledge systems available globally.

In a study, both oregano oil and isolated carvacrol reduced the activity of murine norovirus (MNV) within 15 minutes of exposure [4]. MNV is highly contagious and the primary cause of stomach flu in humans. Oregano oil and carvacrol have also been shown to exhibit antiviral activity against herpes simplex virus type-1 (HSV-1), rotavirus, a common cause of diarrhea in infants and children, and respiratory syncytial virus (RSV), which causes respiratory infections [5].

It is a licorice-flavored plant that may fight certain viruses. A study showed that fennel extract exhibited strong antiviral effects against herpes viruses and Para influenza type-3 (PI-3), which causes respiratory infections in cattle [9].

It is always best to chop or crush garlic before consuming it, because it works better when in contact with oxygen. Garlic is a popular natural remedy for a wide array of conditions, including viral infections. In a study in 23 adults with warts caused by human papillomavirus (HPV), applying garlic extract to affected areas twice daily eliminated the warts inall of them after 1â??2 weeks [12]. Additionally, previous studies reported that garlic may have antiviral activity against influenza A and B, HIV, HSV-1, viral pneumonia, and rhinovirus, which causes the common cold. Clinical trials on animals indicate that garlic enhances immune system response by stimulating protective immune cells, which may safeguard against viral infections [13].

Research findings demonstrate that ginger extract has antiviral effects against avian influenza, RSV, and feline calicivirus (FCV), which is comparable to human norovirus [16].Additionally, specific compounds in ginger, such as gingerols and zingerone, have been found to inhibit viral replication and prevent viruses from entering host cells [17]. Powdered ginger mixed with pulverized cloves, cardamom and caraway has been used for digestive ailments since ancient times.
