Can Drinking Fermented Tea Prevent COVID-19?!

Did new Chinese research prove that you can prevent COVID-19 infections by drinking fermented tea?!

Take a look at the viral claim, and find out what the facts really are!

 

Claim : Fermented Tea Can Prevent COVID-19!

This message has gone viral on WhatsApp and social media platforms, claiming that new Chinese research has proven that you can prevent COVID-19 infections by drinking fermented tea!

Chiayi Chang Gung Hospital, and China Medical University published: The so-called principle that drinking tea can prevent coronavirus is as follows:

Scientists put the virus into the tea water and let it stand for 1 minute~ They found that 90% of the virus in the tea water was killed. It can kill 100% if left for 3 minutes. Especially tea species with a high degree of fermentation (such as black tea/Taiwan oolong tea/Pu-erh cooked tea, etc.) have a good bactericidal effect~because the virus survives on the oral and nasal mucosa when it is just infected.

Drinking tea at this time can destroy the virus cell wall and flush the virus into gastric juice to kill the virus. There are tea products with high thearubigin content at home that can be drunk at any time after brewing~ As long as the tea leaves are less irritating, they can be drunk all day without causing headache/stomach pain or scraping of the stomach/tea that does not affect sleep can effectively prevent the epidemic.

Please share this information~ Drink more tea to help yourself and use kind knowledge to help others.

Truth : Fermented Tea Cannot Prevent COVID-19!

This is yet another example of COVID-19 fake news circulating on WhatsApp and social media, and here are the reasons why…

Fact #1 : No Evidence Of Such Research

First, let’s start with the fact that there is no evidence that the Chiayi Chang Gung Hospital, and the China Medical University – both from Taiwan, ever published joint research proving that drinking fermented tea can prevent COVID-19 infections.

Back in March 2020 (before COVID-19 vaccines and treatments were developed) researchers at the Chiayi Chang Gung Hospital’s Department of Traditional Chinese Medicine used a computer program to identify potential antiviral components in traditional plants.

They identified theaflavin – a polyphenolic compound found in black tea leaves, as a potential inhibitor of protease activity in the SARS-CoV-2 virus. Thearubigin mentioned in the viral message is an oxidation product of theaflavin.

The head of that research team, Wu Ching-yuan (吳清源), claimed that its antiviral effect was similar to remdesivir. But since its publication in March 2020, there has been no further development on using theaflavin to treat or prevent COVID-19.

Even remdesivir was found to be ineffective against COVID-19, with the WHO recommending against its use in November 2020.

In any case, the researchers did not even claim that drinking tea – whether black or fermented, can prevent COVID-19 infections.

Fact #2 : SARS-CoV-2 Is A Respiratory Virus

The SARS-CoV-2 virus is a respiratory virus, which means it primarily infects you through your respiratory system, and to a lesser extent – through your eyes.

Therefore, drinking hot water and drinks, even coffee or tea, has absolutely NO EFFECT on the SARS-CoV-2 virus.

This study identifies possible associations between COVID, the vaccine and the development of SJS/TEN.

We propose three theories for this seven-fold increase in case number; a virus induced, a vaccine induced and a threshold lowering pathway.

We advise future research investigates the impact viruses such as SARS-COV-2 have on immune mediated diseases such as SJS/TEN.

Fact #3 : COVID-19 Is A Virus, Not Bacteria

The viral message claims that highly-fermented tea like black tea, Taiwan oolong tea, Pu-erh kills the COVID-19 coronavirus, because they have “good bactericidal activity“.

This is like pointing out that water has good firefighting activity while recommending it for cleaning an oil spill… The creator of this fake news does not seem to understand that SARS-CoV-2 is a virus, not bacteria.

The viral message also wrongly claims that the COVID-19 coronavirus has cell walls. As a virus, SARS-CoV-2 does not have any cell wall. It only has a protective protein coat called a capsid.

Fact #4 : SARS-CoV-2 Is Sensitive To Temperature

It is no surprise that the SARS-CoV-2 virus is sensitive to temperature. This has been confirmed through numerous research early in the pandemic. You don’t even need boiling hot water or tea to kill it!

At normal room temperatures, 90% of the virus will be automatically destroyed / deactivated after 20-50 hours. But if you raise the temperature to just 54.5°C, the time is cut down to less than 1 hour!

Based on those research, conservatively, the COVID-19 coronavirus can be killed by simply heating contaminated objects for:

  • 3 minutes at temperature above 75°C (160°F).
  • 5 minutes for temperatures above 65°C (149°F).
  • 20 minutes for temperatures above 60°C (140°F).

Needless to say, at 100°C, the virus is instantly destroyed. There is no need to leave the virus in boiling hot water / tea for 3 minutes to kill it, as the viral message claims.
