Oolong Tea Health Benefits for High Blood Pressure

In this 2004 study of the long-term effects of drinking tea on high blood pressure, results showed that drinking oolong or green tea regularly can significantly lower your risk of developing high blood pressure.

In the study, which examined the tea drinking habits of over 1500 participants in Taiwan, the risk of developing hypertension decreased by 46 percent for habitual tea drinkers who consumed at least 120 ml (1/2 cup) oolong or green tea daily for at least one year. For those who drank over 600 ml (2 1/2 cups) oolong or green tea each day, that risk was decreased by 65 percent.

Tea consumption for more than a year did not lead to additional risk reduction.

Oolong Tea and Type 2 Diabetes

Twenty participants with type 2 diabetes taking prescribed hyperglycemic medication participated in this 2003 study conducted in Taiwan.

After consuming 1500 ml (about 6.3 cups) Chinese oolong tea each day for 30 days, the study participants had significantly lower blood sugar levels. (Chinese, rather than Taiwanese, oolong tea was selected for the study because its shorter oxidation process typically results in higher levels of antioxidants in the tea.)

More oolong tea health benefits... the study also found that oolong tea in combination with hyperglycemic medication was more effective in lowering blood sugar levels than the medication alone.
