Preventing the Flu By Gargling Tea

While I was reading up on the latest H1N1 virus information, I came across an interesting study that measured how tea could prevent influenza. It seems you don’t even have to drink the tea, you can just gargle it. The study Gargling with tea catechin extracts for the prevention of influenza infection in elderly nursing home residents, which came out in 2006, took 124 elderly residents and divided them into two groups.

  • Tea Catechin Group – Gargled 3 times a day with a solution that contained tea catechin extract.
  • Control Group – Gargled 3 times a day with a solution that had no tea catechin extract.
  • The study took place over 3 months.
  • Both groups were vaccinated with an influenza vaccine.

What was the result?

  • The Tea Catechin Group had a 1.3% infection rate.
  • The Control Group had a 10.0% infection rate.

That is a reduction in infection rate of 87%. I’m guessing this is encouraging news for those people sensitive to caffeine that wish to get health benefits from tea catechins. Just gargle away! According to the Wikipedia page on Catechins, other health benefits include:

  • Reduced risk of stroke, heart failure, cancer and diabetes.
  • Skin protection from UV radiation-induced damage and tumor formation.
  • Antibiotic properties.

How bad could flu season get this year? One measure is to look at places in the Southern Hemisphere that are going through winter right now. From The Human Condition blog on Newsweek:

In Argentina, 20 to 25 percent of the population has been attacked by the flu over a three-week period. That could easily occur in the United States, where pandemics typically attack between 25 percent and 40 percent of the population.

I’m making some tea right now. Not that I fear H1N1. Any flu is to be avoided. No gargling for me though. Tea is too tasty not to consume as intended.

Michael Allen Smith fell in love with coffee while attending college. Shortly after graduating college, he found himself in the Tampa Bay area far away from the good coffee he had at The Ohio State University. That is when he starting home roasting coffee.

He has visited close to three hundred different coffee places in Seattle, Portland,Vancouver and San Francisco and met many of the top roasters and baristas in the country. Since 2009, Michael has been the Organizer of the Coffee Club of Seattle, which is a Meetup group of over 800 coffee enthusiasts. Besides the social aspect of the group, the Coffee Club of Seattle partners with local coffee professionals for educational events such as coffee cuppings, brewing demonstrations and roasting tours.

Unrelated to coffee, Michael has a personal blog at which covers several topics including fitness, cooking and economics.
