Home » Green Tea could help Prevent Cold and Flu Symptoms
The Facts:
- A proprietary formulation of Camellia sinensis (green tea) capsules helped prevent cold and flu symptoms in healthy adults treated twice daily for three months.
- Daily symptom logs showed that approximately a third fewer patients taking green tea capsules reported cold and flu symptoms compared with placebo during the 3-month period.
- Camellia sinensis was also found to enhance T cell function compared with placebo.
Dr Shaun Holt:
Camellia sinensis (CSF) is another name for the tea plant and the levels of oxidation of the leaves lead to the different varieties such as white, green and black tea. This placebo-controlled trial found that green tea capsules had significantly fewer cold and flu symptoms over a 3 month period. Importantly, this study also found a mechanism by which this benefit occurs – an increase in immune activity in certain white blood cells.
