Since the first outbreak of COVID-19 happened in WuHan when doctors and nurses were doing their best to save live in hospitals and citizens were doing their best to follow the lock-down policy in order to reduce the burden to the medical helps that are need to the Coronavirus fight in that most critical and horrified moment, specialists in different disciplines have been working closely in China, including virus and medical research experts for medicine and vaccine, in meantime, there were many experts in TCM (Traditional Chinese Medicines) and tea research area started to deepen their research from the past health benefits to specifically against the virus reactions or immunity system research; such researches are still ongoing today.
When the effective curing medicines that don’t create other health problems and proven effective vaccine are not yet available, there are more and more people turning their head to find ‘solutions’ from tea.
Before we enter the discussion about what can tea do for us to fight against COVID-19 virus, I think it is important to establish a clear understanding and repeat the fundamental professional protocols that we need to follow:
Tea does can provide many health benefits but shouldn’t consider tea as cure to disease.
Whenever you have healthy, always suggest to check with your family doctor and/or specialist before following from what were written in books or social medias by anyone, neither from so-called “Guru” nor amateurs.
Those who would like to be seen and respected as ‘tea sommelier’ definitely should take the responsibilities more strict, we can share and give suggestions based on confirmed scientific research data and facts, but may not play the doctor or medicine specialist roles.
I am very fortunately to have Prof. Wang FangCheng from Academia Sinica from Beijing, as good friend who I share the same passion for the facts and data researches in tea. So whenever I read something interesting on line, I have a ‘double-checking windows’ to verify the accuracy and authenticity about the scientific research.
There are indeed two major tea research centers in China are devoting their resources and expertise to deepen their researches in tea and both have very encouraging progress that related to the researches to Coronavirus, one is Zhejiang University Agriculture Department and the other one is Yunnan Agriculture University.
According to the Director of Research Center lead by Prof. Wang XuanJun, actually the FDA from USA has already approved the use of plant derived tea polyphenols for external use in 2006, which is used to treat diseases caused by virus. Therefore research in antivirus functions from tea polyphenols is an important focus by tea research experts. Since the outbreak happened in WuHan, his team has deepened the research on tea polyenols for Coronavirus.
Prof. Wang’s research does not limit to Camellia sinensis only, actually in his lab his teams have tried to isolate 800 compound structures from 110 plants, including tea, honeysuckle and grapes; the computerized analysis showed 20 compounds have the potential to bind the S protein on the surface of the virus. “Of course, there is potential gap between computerized analysis vs. reality that we need to investigate further”, according to Prof. Wang. Prof. Wang and his teams so far have continue the actual binding test in which they discovered five compounds are preferred, and block experiments are performed at the molecular level. The blocking experiment means when compounds are present whether can block the virus from binding to the receptor. If compounds can’t block the virus from binding, then it is meaningless with the claim for unite.
Based on the current research result, they discovered EGCG, a catechin monomer component in tea polyphenols in tea, can effectively block the binding of S protein to receptor ACE2 and almost 6 EGCG can achieve the ability of one human receptor to bind to viral S protein. This is a very good news for tea lovers.
Many people thought only green tea has EGCG, as matter of fact, EGCG is one of richest compounds (80%) in catechin, as matter of fact richer EGCG can be found in large-leaf Pu’erh (Sheng) and green tea. When analyzing Theaflavins (yellow color), thearubins (red color) and theabrownins (brown color) in black tea from the tea process, they found theaflavins can also vind to S protein. Tea lovers can appreciate the theaflvins more from the golden tippy black tea.
What is amazing about tea is may be there are only small differences in tea polyphenol structures but the functions may be completely different, and that reflects the mysteries in life and Nature.
Due to the time rush and data were not sufficient enough, therefore Prof. Wang and his teams will continue with the research, they will only announce the final result after having sufficient data and facts.
At the same time, the experts in Zhejiang are studying how the warm tea drink to the relapse of virus infection. Any research, either medicine, vaccine or tea, that related to COVID-19 Coronavirus require very struct research attitude, quantifiable and verifiable data and facts. But with diligent and strict scientific researches we do can sense the light at the end of tunnel for Coronavirus.
Various health benefits that different kind of tea have already been scientifically confirmed, and people simply need to enhance the most foremost important learning – Listen to your body & respect your conditions but not follow information blindly and carefully choose pure and authentic quality tea, take responsibility for own decision. When you think you deserve the best, then learn to respect tea and the Nature.
During the interview by the Yunnan TV & Radio, Prof. Wang XJ said “there is no double drinking tea is good for health, but in order to reach the potential objective to prevent and cure from the virus, perhaps it is better use the extract of effective compounds, we are deepening the research on the application side, hopefully can provide more data to the research for COVID-19 Coronavirus.”
The spike of COVID-19 pandemic rage the world by surprise; the announcement for lock-down took us by surprise; we have been hoping for reopening, but the announcement for gradually reopening gave us some joyful news, in the meantime, start to question ourselves “What and How should I do to cope with the new way of living”.
When we are in the process of preparing ourselves for the reopening, we probably also need to prepare ourselves to accept that most people are facing a same challenge that we will not able to have old life back so easily, the COVID-19 pandemic forced us to change our social behaviors and the way of living for an unknow period of time ahead.
Actually the more I practice the Chinese tea ceremony, it is more clear why it’s helpful for everyone to manage the isolation and stress in the lock down period:
With tea, we learn to engage with ourselves through silence and simple focus
With the simple way of tea serving and sharing, we connect with other person who share the tea with in much calmer and peaceful manners.
With the practice of simple Chinese tea ceremony, even as short as one minute is a complete 60 seconds
When enjoy a cup of tea, there is no desire, no fear, no judgement, but simply pure concentration and appreciation
The nasty COVID-19 Coronavirus urged us to rethink what and how we should take actions for our future starting from today: Environment, Disinfection, and Unity. Public Health is no longer a government’s responsibility, but we have to take our part of responsibilities seriously.
A friend told me she saw a Pharmacy in Brussels is selling textile mask, washable and can replace the ‘filter’. So my friend asked the pharmacist,are you also selling the filter? The reply was “No”. So question will be, can this kind of textile mask really helps to reduce the risk against Coronavirus without or using ‘coffee” filter?
What is the purpose of wearing mask in this particular time? To create a fancy looking? or try to reduce risk of virus infection, particularly for those who are working in the hospital? It is not a funny joke to see our medical personnel wear non-medical masks in the hospital. Same thing for the citizen who will return to work in the space where they face challenge to keep the safe 1.5m safety distance at work or in the shop or in any venue.
The textile mask is washable and allows reuse. But it should have a protective filter in between two layers of textile fabric. So the question would be : Is there a PM2.5 antibacterial filter between the front textile and inner layer of textile?
I have high respect to doctors and nurses and medical & health specialists because of their education and certificates, but it is sad to watch such unscientific demonstration to the fight against the aggressive Corornavirus.
Hope the following checking points are useful for you to choose the textile mask for the reopening:
The antibacterial efficiency %
The breathing level
You should have more than 1 or 2 masks so you can wash it everyday after use
There is life limited for the antibacterial filter, normally is 7 days under normal conditions
Textile masks are not recommended for those who already have breathing problem or children younger than 3 years old.
The government should be cleared with the import regulation and selling permission in order to avoid the chaotic situation happened to masks
Before the pandemic, masks were allowed to sell freely in shops / supermarkets
when the pandemic happened, retail of masks was not allowed otherwise can face severe fine punishment
Since today the non-medical masks are free to sell in shops
Even though the photo from hospital alert my worries about the ‘professional sense’ from some medical personnel, but still it is better to check with your family doctor or local specialist before buying masks.
Tea and tea culture began from China that silently traveled, integrated in different cultures through human migration. The different selections for the first step have created different tones in tea cultural journeys in the West.
In five thousand years China history, Chinese have been using tea to bridge cultures through trading, tolerate and encourage cultural integration without imposing, encourage the simple concept of sharing for mutual prosperity, solidarity and friendships; it has been further cultivated into Chinese culture when tea eventually embedded in Chinese daily living culture without emphasizing cultural hierachy but the sharing of common wealth, self cultivation and good social behaviours.
However, the West started their tea journey from totally different angles. The initial ideas from those who brought tea to the West from China meant to make money and profit for their own but not for the common wealth. The high tea concept did encourage the growth of afternoon tea culture in England which further influences the tea culture in the world,
The western tea journey did not start as a social drink to promote common wealth of average people but more for rich and selected high society, just like how tea and tea culture were before the 7th century in China. Even though today became a social drink, but the hidden shadow of hierarchical show-case and comparative behaviors are not yet whitened out after the past two decades.
Under the horrified threats from Corona virus pandemic, it is not clear about potential impacts to the global economy, let’s hope the growth of tea drinkers and awakened awareness for solidarity can continue. Perhaps slowly, but let’s make sure it grows surely.
Since the first outbreak happened in Wuhan to the raging global pandemic, we start to have some knowledge about Corona virus based on the accumulated observations and experience from those front line doctors and nurses who scarified or took risk of their live to help those infected patients.
Here is the summary from doctors who worked on the treatment for Cororna virus infection in WuHan, hopefully it gives us a clearer understanding different syndromes from Flue vs. Virus:
Air pollution: Dried coughing + sneezing
Having cold : coughing + slime + sneezing + running nose
Yesterday in New York City press conference, an American doctor said Corona virus is a very nasty virus, because some carriers don’t show any syndromes, otherwise testing positive even with the negative testing from the day before.
Hopefully with the continued down curve of infection numbers and increasing of healing numbers, our government will lift up the “home staying” policy, but it does not mean we should consider “We are freed”. We should still keep high alert because so far there is no effective medicines or vaccines. Even when we are able to reopen, it is better for us to continue the following practices:
Keeping social distancing
Washing hands regularly and thoroughly
Wearing mask in the public, particularly in the crowd environment
The responsible person who takes care and have rights to harvest tea picking from the >500 years old GuShu （ancient tea tree）in WuDong Shan village, for FengHuang DanCong, went to check that growing status, she was shocked by the destroying of some branches.
This crime has been reported and now is handled by the police in FengHuang Mountain Range. Hope they can catch the responsible criminals and punish them severely.
Please don’t even try to think or speak about human rights, because those who.committed such crime don’t deserve any right.
International political driven pressure to China has never seized even with the worsen situation of #COVID19 #Coronavirus worldwide pandemic. Recent unfaired and racist attacks from #mouthmasks eventually have touched the bottom line and are now facing counter reactions from China government.
China strictens the quality standards fir export
Starting from 1/4/2020 not only #mouthmasks but all medical supplies and equipments must have the quality testing certificate/report that product quality have been tested and approved according to China standards in order to receive a quality testing certificate/report issued by any from 48 approved quality verification organizations. Right now there are 48 companies are verified and approved by #CNAS can provide the quality checking and approval certificate; such testing report is issued in Chinese and CNAS logo should be appeared on the testing report. Cargoes will only be allowed for export shipment with such testing certificate/report and requires an written acceptance agreement from oversea buyers.
International quality testing community should work with CNAS to establish an universal quality testing standards in terms of testing methods and acceptance of the testing result. Otherwise no medical supplies can be shipped out. Also transhipment is not allowed.
The international quality testing community shouldn’t downgrade the CNAS quality standards without consulting. Also back fight to deny quality testing report issued by other European countries won’t help the problem situation that we are facing collaterally.
The China government point of view is very clear “
unfair accusations and complaints about the mask quality forced the China
government to set stricter guidelines for the mouth masks export. I hope the linked information are useful for
The point of view from China government is clear : “We do care about the quality of medical supplies for live saving; they don’t have to buy if they don’t accept our standards and testing certificate/report we approved.”
China has suffered a lot from the outbreak of #COVID19 #Coronavirus in #WuHan. They have established very strict quality standards that shouldn’t missed up the international business tractions if importers or buyers did mot pay attention to make clear with specifications and required quality standards.
That’s why for weeks I tried to urge your attention that customers should know what they are buying and should give very clear specifications and quality standards before hands.
Complaints and put the blames to China is not fair to handle the situation, certainly it is not able to ease the pandemic situations that our medical personnel are facing right now.
When virus outbreak happened in WuHan, there were many international donated masks did not meet the surgical masks （N95, FFP3）standards, so they sent medical quality experts from hospitals and Red Cross to classify masks. Those unqualified masks were distributed to community for civilian protection masks use.China and Chinese people did not make any complaints, even though many masks did not meet the medical mask standards, China and Chinese people still showed gratitude to the humanitarian generosity and friendship.
