OBJECTIVE: Determine if a specific formulation of Camellia sinensis (CSF) can prevent illness and symptoms due to cold and flu, and enhance gammadelta T cell function

METHODS: DESIGN: Randomized, double-blind, placebo-controlled study.

SUBJECTS: Healthy adults 18-70 years old.

INTERVENTION: Proprietary formulation of Camellia sinensis (green tea) capsules, or a placebo, twice a day, for 3 months.

Measures of Outcome: As assessed by daily symptom logs, percentage of subjects experiencing cold and flu symptoms, number of days subjects experienced symptoms, and percentage of subjects seeking medical treatment.

Mean in vivo and ex vivo proliferative and interferon gamma responses of subjects' peripheral blood mononuclear cells to gammadelta T cell antigen stimulation.

RESULTS: Among subjects taking CSF there were 32.1% fewer subjects with symptoms (P = 0.035), 22.9% fewer overall illnesses of at least 2 days duration (P = 0.092), and 35.6% fewer symptom days (P < 0.002), compared to subjects taking placebo. gammadelta T cells from subjects taking CSF proliferated 28% more (P = 0.017) and secreted 26% more IFN-gamma (P = 0.046) in response to gammadelta T cell antigens, as compared to gammadelta T cells from subjects taking placebo. CSF was well-tolerated.

CONCLUSIONS: This proprietary formulation of CSF is a safe and effective dietary supplement for preventing cold and flu symptoms, and for enhancing gamma delta T cell function.

Green Tea May Protect Against Colds and Flu

If these studies are correct, then we can assume that green tea(or white tea) protects from colds or flu, improves bone density, protects from cancers and other diseases as well...all that and more.

Yes, the research is promising. But, that's just the tip-of-the-iceberg as far as green tea and health are concerned.

Here's a good link that summarizes the most recent research on this powerful medicinal herb.

That is a very interesting site with lots of information.
I switched from coffee to green tea almost a year ago. Since then I've switched again to white tea, then to organic white tea. I have done alot of research on teas, and have found that white tea has more antioxidants and phyto-nutrients than green tea, with less caffeine, and tastes great.
I will still drink green tea, but prefer white.

Anything is better than coffee.
