Some Benefits Claimed about Tava Tea
Green tea and cholesterol
In a Taiwanese randomised controlled trial, 78 obese women who took 400mg of green tea extract three times a day for 12 weeks experienced significant reduction in LDL-cholesterol and triglyceride levels, and a simultaneous increase in levels of HDL-cholesterol, and the hormones adiponectin (promotes insulin sensitivity) and ghrelin (modulates hunger).

Green tea expands blood vessels
Researchers from Greece tested subjects after they consumed green tea, 125mg of caffeine and 450ml of hot water on three separate occasions. They measured the diameter of the brachial artery in each participant 30, 90 and 120 minutes after they consumed each beverage.
Arterial dilation increased significantly with tea by 3.69%, peaking at 30 min, whereas it did not change significantly with caffeine or water.

Tea is good for the brain
A cohort study of 2501 people from Singapore has found that regular tea consumption is associated with lower risks of cognitive impairment and decline.
The effects were most evident for black (fermented) and oolong (semi-fermented) teas. In contrast, no association between coffee intake and cognitive status was found.

Green tea prevents fatty liver
A US team fed groups of genetically obese and lean mice a diet containing zero, 1%, or 2% green tea extract for six weeks.
At the end of the study, the obese mice fed green tea extract weighed 23-25% less than obese mice fed the non-supplemented diet and the lean mice fed green tea extract weighed 11-20% less those on the non-supplemented diet.
