Doctor's Note

This is the final video of my four-part series about the latest discoveries on tea. See Antimutagenic Activity of Green Versus White TeaIs Caffeinated Tea Dehydrating? and Treating Gorlin Syndrome With Green Tea for parts 1-3. This reminds me of the experiment that involved rubbing what is perhaps the Biggest Nutrition Bang for Your Buck, on the skin—broccoli sprouts. For more on cervical cancer, see Poultry and Penis CancerAmla Versus Cancer Cell Growth; and Cancer-Fighting Berries. For more on wart viruses, see Wart Cancer Viruses in Food, and Pets & Human Lymphoma. That will probably close out my tea review until next year’s batch of articles—I can’t wait to see what’s next!

      I can only imagine the look on my patients faces when they ask, “Doc what can I do about my Genital warts?” and I reach into my pocket and pull out a teabag. . . of Green tea of course.

    • HemoDynamic, M.D.

      Every medical professional should be required to watch Michael Greger, M.D.’s new DVD “Uprooting the Leading Causes of Death.”

      Informative, Intelligent and Highly entertaining it should be required viewing before entering any establishment that sells food.

      The information contained on this DVD (If used) Can and will Save Your Life!

      Support the man who supports Mankind!        (All procedes to charity)

      • SJ M.D.

        Yes – the DVD is absolutely great and presented with great humor. Lots of important information in one hour.

    • Pbeach

      What about plain old warts on your fingers? Would it help there too? Worth a try!

  • GSH

    A new addition to my morning smoothy! Green tea leaves.

    Thanks so much for this! I have to drink decaf green tea because I have lone afib which by the way is much less frequent when my diet is more filled with fresh veges! I am vegan and have been for years now, enjoying your videos and inspirations!
    Is decaf as effective as regular green tea? I hope!

    • Veguyan

      Your decaffeinated green tea may have less
      antioxidant polyphenol catechins than regular green tea.

      Researchers at UCLA measured the antioxidant
      capacity and polyphenol content of 18 teas.

      They found that decaffeinated tea had around half
      the antioxidant capacity of regular green tea.

      However, this loss of antioxidant capacity apparently is related to the decaffeination process. The company Triple Leaf Tea advertises that their decaffeination process retains more of the antioxidant power:


      Now you can enjoy the benefits of green tea without
      the caffeine! Drink Triple Leaf Decaf Green Tea as often as you like anytime of
      day. Experts recommend drinking three of more cups of green tea a day. Our
      Decaf Green Tea is naturally decaffeinated using a carbon
      dioxide process that maintains green tea’s beneficial antioxidants.* 

    • Thank you for such a good information.
      However it is advised for people with HPV and genital warts to try to find out someone to support and love.

  • Scott Harer

    What about HPV positive throat cancers? Any chance green tea might be a good thing to start drinking to prevent/help cure one of those? I have just had a friend with that diagnosis.

    • HemoDynamic, M.D.

      Why wait!  Start drinking the Green stuff now and worry about the research as an afterthought because it can’t hurt.  And there is too much evidence showing that is stops cancer in its cradle.

      Go GREEEN!!!!!

      • SJ M.D.

        No doubt that green tea has health benefits, but there are single rapports of hepatotoxic (liver) side effects, if consuming large amounts for a long period of time.

        • HemoDynamic, M.D.

          Maybe it was just because they’re Danish!!  You know how those Danish people are.  ;-)

          Just kidding SJ.  Very interesting for sure but any confounding variables?  I will have to check that out.  I would love to see the original study!

          • SJ M.D.

            You are a true poet!

            Just a case rapport, so the science is “not strong”. There are ref. to other articles though – not read them yet.

        • HemoDynamic, M.D.

          Hey SJ how did you know (or guess) I grew up in San Diego?  You never answered my reply before and I am curious if we may know some of the same people in Denmark.

          • SJ M.D.

            Dr D,
            Lucky punch! You know my name, I dont know yours. Once in a while I search the internet to look for “Plant Strong” or vegan doctors. Even tried to find you! Googling “HemoDynamic” does not help :-) In Denmark they are hard to find! As I recall it, I saw the name of some “vegan doctors” in California, and I wondered if one of them were you. I am going to a congress in San Diego later this year, so I just figured if you work in S.D. I would have visited you!

          • HemoDynamic, M.D.

            My name is Jim Bennie, I grew up in San Diego and it was beautiful back then but it is too crowded, too expensive and has too much gang activity to raise a family.  I live in Northern Cal now about 900 miles away from SD.  It would be great to meet up with you someday for sure.  There are so few Vegan Docs that we need to stick together like pressed garlic!

          • SJ M.D.

            One day we will meet and share a carrot!

          • SJ M.D.

            Connect via Linkedin? I have send an invitation.

          • HemoDynamic, M.D.

            Stephen,  I am connected via linked in but it wouldn’t let me connect with you.  I will leave this post up until I get a reply and then I will remove it.  My email is I think that is the one that linkin is registered to but I am not sure.

          • SJ M.D.

            I have send an e-mail to hotmail and tried via linkedin again.

    Is there any concern about taking green tea extract soft gels orally?  I have 100 mg Blue Bonnet soft gels.   

  • Sebastian Tristan

    I use a vinegar/tea solution for my dermatitis. It doesn’t cure it, but it keeps it at bay.

    • Youcef

      Have you tried different concentrations?

  • Cindy in Mnl

    I’ve had this condition for approximately 28 years, and only started drinking 5 glasses of green tea a day for the past two months. Suffice it to say, they’ve completely disappeared. Thank you so much, Dr. Gregor!!

    • veghead

      Wow really? Were you incorporating any other methods to help as well or just the green tea?

  • Ed

    Wow amazing! I take two green tea pills every day. And I also drink green tea, organic coffee and drink echinacea tea. I found out when I was like 17 I got the kind of hpv that causes cervical cancer. I started taking drinking green tea every day and excercising, as well as watching what I eat. In 6 months I clearned the virus. Never underestimate the power of food!

  • HealMe

    $900 per tube of the green tea ointment (Veregen) I understand (unconfirmed). Don’t know what size tube. Would the price go down if in a larger metro area OR if more dr’s prescribe it? Unknown if carried on popular insurance companies’ formularies. Anyone know the economics of this?

  • Alan
