My intent is for Tea Deviant to be a positive place to inspire curiosity and have fun while exploring, but I can’t ignore the proverbial elephant in the room. Considering COVID-19 still has a daily impact on our lives and a study on tea and the virus in vitro has been done I feel it’s worth sharing and hope you do too. I’m not interested in fake news. This is not about a definitive cure. It's about studies that show the potential for compounds found in tea to be helpful against the virus and staying informed.
In November 2020 Nara University in Japan conducted a study on the effect of catechins in black and green teas on COVID-19 in vitro. Various teas were used with the most effective being black tea brewed from tea leaves. The study showed that when that black tea was introduced to coronaviruses it reduced their ability to infect by 99% after one minute and 99.9% after 10 minutes.
I first saw news of this study on the Japanese Greentea Co website. I did some further searches, but could not find an abstract though I did find other articles:
“Nara University study finds some common teas can neutralize COVID-19”
“Detoxify the New Corona with Tea…”
Human beings are more complex than a petri dish in a controlled environment for sure. Still, this study combined with others on tea and COVID-19 along with tea and other illnesses have me thinking there is something to this idea.
Other Tea and COVID-19 Studies
Before the Japan study, in July 2020 the National Institute of Health released info on studies that focused on 2 tea polyphenols: EGCG (epigallocatechin-3-gallate) derived from green tea and theaflavins from black tea. In short, they found both to be worth studying more as they are bioactive with the ability to support physical health in multiple ways . Here is an excerpt :
“Epigallocatechin gallate (EGCG) is one of the most abundant polyphenolic catechin found in Camellia sinensis (L.) Kuntze (tea plant), especially in green tea. EGCG has been tested for its antiviral activity against several viruses and found to be a potential treatment option over synthetic chemical drugs. It is recognized as a multi-functional bioactive molecule exhibiting antitumorigenic, anti-inflammatory, antibacterial, antioxidative, and antiproliferative properties in addition to its antiviral effects (Chacko et al., 2010). Theaflavins (TFs) are another class of polyphenols found in abundance in black tea. The TF derivatives found majorly in black tea are theaflavin (TF1), theaflavin-3-gallate (TF2A), theaflavin-3′-gallate (TF2B), and theaflavin-3,3′-digallate (TF3). All these TFs are being researched for their bioactive properties and are known for their broad-spectrum biological properties, like anti-tumor, anti-viral, anti-inflammatory, anti-oxidative, and anti-bacterial properties. Since EGCG and TFs are of natural sources and consumed regularly by a majority of the population, investigating the anti-viral properties of these polyphenols against COVID-19 could be an advancement in finding a treatment to this latest pandemic.”
EGCG would not appear to be effective taken orally though:
“However, EGCG is unstable and when consumed orally has low bioavailability. It tends to get oxidized quite easily before it reaches the target. Hence, many studies have suggested structural derivatives of EGCG to enhance its bioavailability.”
Tea Fights the Common Cold and the Flu
In previous studies tea catechins have been found effective against other viruses including influenza and the common cold. They showed antiviral capability and immune support. References to studies done since the 90s indicate that drinking green tea with consistency reduces the chance of flu.
I think tea just feels good too, and feeling good has also been linked to higher immunity.
Does the addition of milk affect the benefits of these powerful tea compounds? I found this scientific review from 2015 that covered various studies on the effect of milk (even non-dairy) on the beneficial properties of tea. The studies referenced resulted in wide ranging results thought to be caused by variables like type of tea, brewing method, type of milk and ratio of tea to milk. Even though some studies indicated a positive effect, overall the review stated that milk in tea was more likely to have a masking or negative effect.
This article from Food Chemistry details that though regular sweeteners like sugar had a negative effect on antioxidants in tea, stevia did not. I am not ready to give up my raw honey in my morning tea, but I am happy to have my tea au naturel during the day. How about you?
Whether it’s the taste of your tea, the ritual of it, or the relationships forged over it I hope it brings you joy. We need every ounce of that to come out on the other side of this viral war intact.

Covid-19 took my Mom this week. I know I am just one of many thousands dealing with this, but for those who aren’t I wanted you to know why there’s been radio silence on the blog and socials. Tea Deviant was always meant as a place of fun and discovery and a step away from the pressures of life. It will be that again, but it has been hard to create that content during this time.
The hardest part of this is that she was in a medical facility prior to covid for other health issues and during all of this time she was not allowed visitors. 10 months. My sister got to see her through a window once. I know she knows she is loved, but I hate to think of her enduring all this without direct connection with family and friends. I am grateful to all of the PAs, nurses and aides, many of whom were kind and loving toward her. I don’t believe death is a full end, but I do believe grief is a process that I need to get through.
I look forward to coming back with more tea adventures, a few which are already in the works. One will virtually take me overseas. Until then, to all who have lost friends, family, jobs, homes, and many other things important to the joy of living I wish you strength and peace.

Tea, Grief and Mental Health
Hey tea lovers! I have a couple of very cool tea focused Christmas gift ideas to share with you from Adagio Teas. They sent me their 2020 Tea Advent Calendar and 12 Days of Christmas tea ornaments gift to check out. The video above gives you a sneak peak of what’s inside. Don’t worry, it’s not a spoiler alert. I only show one tea in the Advent Calendar so you can still be surprised with a new tea every day. The 12 Days of Christmas comes with a tea list though, and I do reveal that.
The advent calendar is available in tea bag or loose tea format. Note, the teas for the loose version are different than for the bagged one. So get both! (I like ‘and’ in this case more than ‘or’.)
I have already dug into these teas and want to share notes on a couple. The black Cream Tea, which is in the 12 Days... as Eight Maids a Milking Cream Tea, tastes as good as it smells. I don’t buy a lot of flavored teas but sometimes they just hit the right note. The leaves have a scent of sweet cream. Brewed it is creamy and slightly sweet on its own, but I think the taste is brought out best with honey and a bit of milk.
This tea is also available in a sample size, 3 oz., 16 oz. and a 15 bag box. The tea base is Ceylon and there is no sugar or dairy in it, just natural flavoring.
Another holiday inspired tea is the Pu-erh Chorange, available loose and in bags. It smells and tastes like the classic Terry’s Chocolate Orange candy! (Now I want one.) I liked this tea naked (The tea, not me. Though I have nothing against naked tea drinking. Drink your tea wearing what you want!) It’s also great with a bit of honey to bring out the sweetness. The puerh is gently earthy, round and smooth creating a great base for the balancing act of the chocolate and orange.
On the caffeine-free end I tried the Rooibos Nutcracker. The hazelnut and chestnut notes were what really grabbed my attention in this blend. It also includes apple, cocoa nibs and caramel flavor. I folded some homemade whipped cream in this tea and it was like Christmas dessert in a cup. This is a good one if you want to roll around in the season without getting a caffeine high.
It’s an unusual holiday season for many. I realize I am appreciating every moment of beauty, fun and kindness more than ever. Wishing you some of the joy of the holidays in your cup.
Note: Though Adagio did provide teas I am not an affiliate and these are just links to products mentioned for ease. Enjoy!
“The sequestered situation of this church seems always to have made it a favorite haunt of troubled spirits. It stands on a knoll, surrounded by locust, trees and lofty elms, from among which its decent, whitewashed walls shine modestly forth, like Christian purity beaming through the shades of retirement.” - "The Legend of Sleepy Hollow", Washington Irving
I finally got back to the Hollow this week during daylight to walk the historic grounds of the Sleepy Hollow Cemetery and the The Old Dutch Church, the oldest in the country (estimated at 1685).
A beautiful site with gently rolling hills, loads of foliage, and varying styles of stone work, this place is both a living work of art and of history. Washington Irving, the author of “The Legend of Sleepy Hollow” is buried here. I thought he’d have one of the house-like mausoleums in the cemetery considering how well he was known even in his own time. He was a lawyer, historian and diplomat on top of being a creative writer. Not bad for never going to college and being the 11th child of a sizable family. Not resting in a mausoleum, Irving’s modest tombstone is in his family plot at the cemetery.
“The immediate cause, however, of the prevalence of supernatural stories in these parts, was doubtless owing to the vicinity of Sleepy Hollow. There was a contagion in the very air that blew from that haunted region; it breathed forth an atmosphere of dreams and fancies infecting all the land.”
This is the 200th anniversary of the publication of the tale of the creepy headless ghost that would haunt the dirt roadways of the town at night. The story was published as part of a compilation called The Sketch Book of Geoffrey Crayon, Gent. in March 1820.
This is such a classic spooky tale that has not only survived as a Halloween staple it has inspired TV shows and multiple movies like Tim Burton’s version in 1999. The town is definitely developed, but historic sites like the Sleepy Hollow Cemetery and the Old Dutch Church seem frozen in time. I went on a beautifully overcast day that was not too hot nor too cold, just Goldilocks perfect, and quiet for Halloween season. I even found the Van Tassel plot by pure chance - the family whose daughter Katrina plays such a part in the story.
“It was, as I have said, a fine autumnal day; the sky was clear and serene, and nature wore that rich and golden livery which we always associate with the idea of abundance.”
