Doctor's Note

This is one of the landmark findings that I’m afraid no one will ever hear about because no one profits. No one, that is, except the millions of people spared from infection! I’ve taken a break from my merciless travel schedule (see all my past and future speaking dates!) to work on my 2013 batch of videos. But, whenever I’m back on the road, I hope those 71 seconds protect me from all those airport germs.

    Vitashine Vegan Vitamin D3 is the best flu/cold prevention I’ve come across however taking too much over a long period of time causes insomnia.

  • BrianH

    I only gargled after a sore throat but never thought to it before . And green tea? Gargling with green tea was best all. Amazing!

  • Veganrunner

    Dr Greger thanks for posting your schedule! You are going to be speaking a few blocks from my house March 3. I am coming!

    • SteveK

      Where is Dr. Greger’s schedule posted??

      • Veganrunner

        First paragraph in Doctor’s Notes above. Highlighted.

    • SteveK

      Found it, thanks. Suggest it should be prominent on the home page.

  • Craftymaker

    How often do they recommend gargling, daily? How about the temperature of the water? I’ve always used hot salt water to gargle with.

    • Ray

      This is my question too.

  • Jake

    The yoga assana (posture) known as the “roaring lion”- it involves sticking one’s tongue out towards your chin as far as possible – also relieves sore throat and allegedly helps with a number of other problems. We wonder if the effectiveness of gargling and the roaring lion has to do with stimulating circulation in the throat.

    some may not agree, but I’ve gargled with straight Hydrogen peroxide for about 2 years now, and always! followed up with a gargle rinse of straight warm water at night and have never have had a cold since. Some say good some say bad? it works for me..

    • ted

      You don’t gargle with straight hydrogen peroxide. Getting a drop of merely 30% hydrogen peroxide on the skin feels like a hot fire poker and kills the skin. You probably gargle with 3% hydrogen peroxide.

  • Rie

    Hmmm. I was taught as an RN 20 years ago to gargle salt water for a sore throat. Salt being a killer of ‘bugs’, it makes sense.

  • James Thompson

    Did I missing something? None of the references mentioned using salt in the water.

  • dflores1123

    I was wondering if it matters when you gargle with the salt water? I’m w/ Rie. As an RN the use of salt water for gargling is nothing new for sore throats, but for prevention- that is new-news.

  • beccadoggie10

    Hydrogen peroxide and water also helps eliminate a sore throat. But, I’m not certain if it prevents a cold. Thus far, the best remedy I’ve found to prevent a cold or the flu is common sense. Washing hands often with soap and warm water, using alcohol base sanitizers on shared equipment or while traveling, and eating vitamin A and C rich foods, and ingesting one capsule of Astragalus Root 470 mg once a day.

    Despite our housekeeper coming into our home repeatedly with colds or the flu, I’ve not been made ill, as long as I take low dosage of this herb during cold and flu season.

    On the other hand, my dentist demands the use of patients gargling with Listerine, which I find disagreeable and potentially toxic as I am already chemically sensitive and avoid such unnecessary measures.

    • Nebuladancer

      Sounds more like a requirement for his comfort (not having to deal with bad breath) than a dental health issue.

  • Woodrow123

    Been doing a salt water sinus rinse twice/day for the past 5 years and have had 2 colds in that time. One of the colds was after I’d missed 2 days of the rinse and had been working in a K12 registration department, and the other right after my father passed away..high stress. I used to get colds 3-4 times/year and it always went to my chest. At least 1/2 the time it turned to bronchitis. Think I’ll add the gargle to my routine when things are really getting passed around. It makes sense given the success of the sinus rinse.

    • freerovingbovine

      I asked my MD about avoiding a prolonged cough after a cold. The advice was to exercise, or at least walk around more. The idea is to avoid letting the bug settle in the chest. I tried it, I was grumpy, but it worked.

      • Woodrow123

        Thanks! How much walking? Walking just to move or actually get puffing and break a sweat? I don’t imagine that you’d go to the point of exhaustion though, right?

  • Soeleejmen

    I’m sorry for this question but, is there a risk of taking to much iodine or not. English is not my mother tongue and sometimes it goes all to fast fore me. Can any 1 respond please

  • mciuccio

    Great study, I am going to try it too. However I can imagine 2 yea olds being able to gargle. That seems pretty advanced. Regardless, I am not two and can do it. :)
