1. Green tea has cancer-fighting properties: A catechin called EGCG found in green tea has been linked in various studies to a reduction in cancer rates. It may help in the reduction of the following types of cancer: bladder colon, esophagus, pancreas, rectum and stomach.
2. Green tea consumption linked to lower risk of coronary artery disease: In a Japanese study, researchers found that the more green tea you drink, the less chance you will have of developing coronary artery disease.
3. Green tea may reduce the risk of blood clots and strokes: “Green tea also lowers fibrinogen, which is a substance in the body that can cause clots and strokes.” — “150 Healthiest Foods on the Planet” by Jonny Bowden, Ph.D

7. Rooibos and honeybush teas may help with skin cancer: In one study, rooibos and honeybush extracts suppressed skin cancers in mice, giving hope for a future in human studies.
8. Rooibos may be anti-aging: Or, at least a study done with quail found that it helped their egg production capabilities last longer. Since birds are a proposed animal for anti-aging studies, this holds hope that rooibos may help humans as well.
9. White tea was found to be more protective against oxidative stress when compared to green tea.
10. Rooibos tea (both red and green) were shown to have the highest protection for male fertility against oxidative stress: In a study that tested the oxidative stress reducing properties of supplements made from green tea, red rooibos, green rooibos, or Chinese green tea, rooibos extracts helped protect sperm health the most.
Drinking a variety of teas has been proven to be part of a healthy lifestyle. The sampling of studies above are just a drop in the bucket of a whole sea of research, which makes my tea-loving self feel very good.
