What the mainstream media is hiding
Commercially available black tea inactivates the SARS-CoV-2 virus by up to 99% within 10 seconds – further evidence of how easily the coronavirus pandemic could have been contained with natural remedies.

When “killer germ” panic began to spread around the globe in early 2020, Malak Esseili, a virologist at the Center for Food Safety in the College of Agricultural and Environmental Sciences at the University of Georgia in Griffin, was also concerned. She immediately began looking for ways to protect herself and her family from coronavirus. “Ideally, something that is readily available, easy to prepare, and suitable for the whole family,” she thought.
Inspired by her children’s drinking preferences, Esseili turned to the unassuming tea leaf. A quick trip to the local supermarket – and her research project could begin.
“The coronavirus first colonizes the oral cavity,” Esseili explains her approach. “It multiplies there before migrating to the lungs. Therefore, measures are important – especially those that can be taken preventively at home and without a doctor – to reduce the invading viruses in the mouth, preventing a high viral load from reaching the lower respiratory tract in the first place.” Esseili and her doctoral student Julianna Morris discovered how astonishingly easy this can be when they tested 24 different teas for their antiviral properties.
The scientists prepared infusions of each tea variety and mixed them with the SARS-CoV-2 virus for five minutes at 37 degrees Celsius. They further investigated five varieties that most significantly reduced the pathogen’s infectivity: At two concentrations – 40 mg/ml and 10 mg/ml – they mixed each tea with virus-containing saliva, sometimes for one minute, sometimes for just 10 seconds.
As it turned out, black tea was the most effective: At a concentration of 10 mg/ml, it reduced the coronavirus’s infectivity by a whopping 99.9% within just 10 seconds.
Green tea, mint tea, eucalyptus mint tea, and Raspberry leaf and hibiscus flower tea, however, reduced the virus’s contagiousness by only 96 to 99%.
At a higher concentration – 40 mg/ml – all five tea varieties achieved a reduction of over 99.9% within 10 seconds.
The teas provided the most pronounced protection, 99 to 99.9% when they were able to act in saliva at the same time as the virus infection. Afterward, they reduced infectivity by 94 to 98%, compared to 68 to 90% previously – i.e., preventatively.
For preparation, the virologist recommends steeping 10 grams of tea per liter of water for 10 minutes – and then consuming it without milk or sugar, whether as a drink, as a mouthwash, or for gargling.
What is the antiviral effect of the teas based on? Esseili attributes it primarily to secondary plant substances from the group of polyphenols. The more of these the tea contains, the more pronounced the effect. It reduces viral infectivity.
How so? Some polyphenols directly interfere with the virus’s replication cycle: Some inhibit enzymes without which it cannot replicate; others block its binding to ACE2 receptors; and others bind to the spike protein or the ACE2 receptor, thereby preventing the virus from entering the host cell. Beyond these direct antiviral effects, polyphenols strengthen the immune system, mitigate excessive inflammatory responses, and promote the activity of interferons and natural killer cells, thereby reducing the viral load.
And what about the virus’s second route of entry into the body, through the nasal mucosa? Nasal sprays made from tea could protect against it.
Willfully missed opportunities
What would have become of the coronavirus pandemic if health authorities had recommended such simple self-protection to the population from the very beginning of the pandemic – in conjunction with other measures that would have been just as easy and comparatively inexpensive to implement? With antiviral mouthwashes like Betaisodona, “we would never have needed a lockdown,” hygiene expert Prof. Klaus-Dieter Zastrow assured early on when the entire world had succumbed to the killer germ panic. Nebulized hydrogen peroxide would also have reliably eradicated SARS-CoV-2 – not only on surfaces and in indoor aerosols but also in the bodies of infected individuals. Vitamins C and D, as well as minerals like zinc, could have been used extensively to strengthen the body’s defenses. In addition to tea, many other plant substances have anti-inflammatory and immunomodulatory effects, from quercetin and resveratrol to thyme, sage, and licorice root.
The COVID-19 years offered natural and empirical medicine a historic opportunity to rise like a phoenix from the ashes. But it wasn’t allowed to. It would have brought disaster to the billion-dollar business with ineffective, side-effect-rich “vaccines” and antiviral drugs such as Remdesivir, Molnupiravir, and Paxlovid.
