Benefits of Green Tea for Boosting Antiviral Immune Function

August 19, 2019

[Music] the belief of green tea is a wonder weapon against diseases dates back thousands of years I’ve talked about it in relation to chronic disease but what about infectious disease interest in the antimicrobial activity of teeth dates back to a military Medical Journal in 1906 suggesting that servicemen fill their canteens with tea to kill off the bugs that caused typhoid fever however this effect of tea was not studied further into the late 1980s when tea compounds were pitted against viruses and bacteria in test tubes and petri dishes but what we care about is do they work in people I had dismissed this entire field of inquiry as clinically irrelevant until genital warts external genital warts caused by human or the most common and fastest spreading venereal diseases worldwide patients with external genital warts present with one or several cauliflower-like growths on the genitals and or anal regions considerably impairing people’s emotional and sexual well-being but rub some green tea pointment on and you can achieve complete clearance of all warts in more than 50% of cases Wow if it works so well for wart viruses what about flu viruses works great in a petri dish but what about in people tea drinking school children do seem to be protected but you know know until it’s put to the test if you give health care workers green tea compounds they come down with the flu about three times less often than those given placebo in fact just gargling with green tea may help while a similar effect was not found in high school students gargling with green tea may drop the risk of influenza infection seven or eight fold compared to gargling with water in elderly nursing home residents where flu can get really serious unlike antiviral drugs green tea appears to help by boosting the immune system enhancing the proliferation and activity of gamma delta T cells a type of immune cell that acts as a first-line defense against infection subjects who drink six cups of tea per day head up to a 15 fold increase in infection fighting interferon production in as little as one week but why there’s actually a molecular pattern shared by cancer cells and pathogens and with edible plant products such as tea apples mushrooms and wine so eating healthy foods may help maintain our immune cells on ready-alert effectively priming our gamma delta T cells that can then provide natural resistance to microbial infections and perhaps tumors I guess I shouldn’t have been so surprised t after all is a vegetable infusion you’re basically drinking a hot water extraction of a dark green leafy vegetable [Music]

    5 cups a day of Oolong green tea, a fermented Chinese tea, has helped with my psoriasis as well as detoxing. The taste takes getting used to.

    Hey, I just discovered that I can support the work of NutritionFacts.Org and Dr. Greger by selecting "NutritionFacts Org" as my Amazon Smile non-profit for donations! I just made a large Amazon purchase, and it's great to know that some of that money will go to help Dr. Greger and his staff to continue their extraordinary work of spreading the truth about nutrition and the importance of a plant-based diet!

    Could i plant a green teat plant – and than eat leaves? Is that better than tea?

    Thank you, Dr.Greger…Great video.

  • Reply Vladimir Yuvachov March 20, 2017 at 4:35 pm

    There are too many awkward pauses in this video. You can tell that they added time in between Dr. Greger's speech. It doesn't listen nicely.

    Is decaf just as effective?

    Daily 1-2 cups of green tea + regularly washing hands = best flu shot ever.

    Dr. Greger and the team, I like this rendering of the data done by Tyler McReynolds better than the previous video's rendering. What I like here is the highlighted and focusing on the specific sentence that Dr. Greger is referring to and quoting about. This directs the viewer to the relevant passage in the research and adds enhanced context. I also like the transition to the next research paper wherein the page is rendered and then, again, the relevant text is highlighted. All in all, the fact that the team is a) making enhancements and b) allowing fans and viewers to weigh in speaks volumes about all of you. You are spectacular and I am all the healthier for it all.

    I only drink de-caffeinated green tea. Does de-caf green tea have the same benefits?

    I thought the presentation format of this video was much better than the last. The graphics cleanly presented the supporting information with out looking like an elementary slideshow. The pace and flow of dialog was also spot-on, no long pauses and not too quick.

    This video is so much better. The vitamin D video looked like a 90s video and was moving so much while you read.

    Thanks for an informative video.. is there any negative effects of the caffeine? if so, are these outweighed by the benefits?

    Will drinking decaf green tea diminish the medicinal properties?

    I drink organic green tea in the same mug that I drink organic coffee in. I infrequently wash it and I think that the tea disinfects it to a degree.

    Lol I drink 2 cups of matcha every day, and some of green tea infusion.My ancestors were from Okinawa (One of the Blue Zones, the place where people reach one hundred years easily). Maybe matcha is one of the reasons from these people.

    caffeine is a stimulant drug. caffeine is for the weak who can't get their energy from normal everyday food using caffeine is no different than using heroin or speed or any other hard drug it'll eventually wear you down and kill you don't believe the lies of green tea or coffee or any of the rest of it caffeine is a stimulant drug poison.
