Antiviral activity of green tea and black tea polyphenols in prophylaxis and treatment of COVID-19

The highly rapid spread of the novel coronavirus called SARS-CoV-2 or nCoV is the worldly concern today during the currently ongoing pandemic. This pandemic has caused the majority of countries all over the world to levy lockdowns in their vicinities and undertake strict measures to prevent the virus. Apart from the medicines prescribed by the healthcare specialists, the numerous preventive measures have been introduced by the doctors, nutritionists as well as laymen themselves to fight against the COVID-19. Therefore, people are relying on remedies, good diet, healthy living habits and such other measures.

In this regard, during critical times, green tea and black tea rose to be the preventive dietary elements which people found out to be counting on largely. And they did so for good reasons, after all.

Since no vaccine was approved for a year and the current vaccines being introduced by the health organisations still need time to prove themselves, people counted on the natural tea remedy to keep their immune system strong enough against the corona virus. So as an alternative way of covid-19 treatment and prophylaxis (which means prevention from the spread of the disease even further), the role of green tea and black tea becomes very positively crucial, thanks to the naturally derived substances of these teas which are highly known for their excellent antiviral properties.

Several many researches have been made recently to confirm the effectiveness of green tea and black tea in prophylaxis and the virus treatment. We brought up those researches to inform you in the simplest possible ways. So, bear with us for your own good!

Polyphenols are known as an extensive family of organic compounds which are naturally occurring and are characterized by phenol units in multiple numbers. The researchers reviewed two polyphenols which are derived from green tea and black tea, that is epigallocatechin-3-gallate (EGCG) and theaflavins respectively. This scientific review was done to analyse the antiviral properties of both the teas against the corona virus and if they were helpful in the activity of prophylaxis. As a result, both polyphenols of the green tea and black tea were found to exhibit strong antiviral activities against a variety of viruses, including single-stranded RNA viruses, like COVID-19.

The studies revealed the possible impacts of the interactions between the viruses and tea polyphenols. EGCG and theaflavins, especially theaflavin-3,3′-digallate (TF3) derived from the black tea were found to have shown a prominent interaction with the virus.

Furthermore, when EGCG derived from green tea is concerned, it has been resulted that for the antiviral activity against viruses like COVID-19, it proves more beneficial in treatments than the synthetic chemical medicines and drugs. EGCG is hence, recognized as a bioactive molecule which multi-functions and also exhibits anti-inflammatory, antitumorigenic, antioxidative, antibacterial, and antiproliferative characteristics. This way we come to understand that not only green tea is highly advantageous against the viruses in terms of its antiviral effects but way more than that.

Similarly, the Theaflavins (TFs) extracted from the black tea abundantly constitute of another classification of polyphenols. The derivatives of TF which are majorly found in black tea include theaflavin (TF1), theaflavin-3-gallate (TF2A), theaflavin-3′-gallate (TF2B), and theaflavin-3,3′-digallate (TF3). All of these TFs classes have been under study with regard to their superb bioactive properties. These three black tea elements are also known for their broad-spectrum biological properties which include anti-tumour, anti-oxidative, anti-bacterial and anti-inflammatory properties. Like EGCG, we come to find TFs similarly medically proven to be effective in various medical treatments, apart from the anti-viral characteristics.  

Since both the polyphenols, EGCG and TFs are extracted from the natural sources and are also consumed by the majority of the population on regular basis, we all must be familiar with the anti-viral properties of these polyphenols against COVID-19 and get benefitted from them.

So, let’s look over the antiviral properties of EGCG and TFs individually now.

Epigallocatechin-3-gallate (EGCG)

EGCG was found to ward off the harmful effect and spread of deadly dangerous viruses in the past like Porcine reproductive and respiratory syndrome virus (PRRSV), Hepatitis C virus (HCV) infection, ZIKA virus, intracellular chikungunya virus replication, influenza virus, HIV-1 -CD4 and other regular diseases, too. As we see the evident fighting capabilities of this magical element of EGCG extracted from the green tea due to its antiviral properties, we find out the potential of EGCG for the COVID-19, too. Surely, the polyphenol EGCG with its wide spectrum of antiviral agents features a defence mechanism which proves to be fruitful in treating different infections time to time.

Theaflavin polyphenols (TFs)

Similarly, like the polyphenol ECGC from the green tea was found to be affective against the corona virus, researchers had the same opinion about the theaflavin polyphenols extracted from the black tea too when it came to its antiviral attributes. The TF derivatives extracted from black tea have been tried and tested for prophylaxis and treating COVID-19. Like ECGC, these polyphenols pf black tea were proved to treat multiple viruses in the past.

Therefore, now when the benefits of green tea and black tea have been medically proven to assist patients against viruses including the corona virus which has caused the world to go crashed, everyone of us must get our hands on the organic teas. Meanwhile, only those green teas and black teas are recommended by the health specialists which are far away from the addition of any synthetic compounds, artificial colours and dyes, additives and all such other corrupting and adulterating materials.
