Basics
Black tea is a true tea made from leaves more heavily oxidized than the white, green, and oolong varieties. Black tea is generally stronger in flavor and contains more caffeine than the more lightly oxidized teas. While green tea usually loses its flavor within a year, black tea retains its flavor for several years. For this reason, it has long been an article of trade, and compressed bricks of black tea even served as a form of de facto currency in Mongolia, Tibet and Siberia into the 19th century. Traditionally, black tea was the only tea known to Western culture. Although green tea has been gradually increasing in popularity, black tea still accounts for over ninety percent of all tea sold in the West. |

| A new study suggests that black tea reverses blood vessel dysfunction in patients with coronary artery disease, which reduces the risk for heart attack and stroke in these patients. In their crossover study, the scientists asked 66 patients with coronary artery disease to drink either 4 cups of black tea or 4 cups of water daily for 4 weeks. Investigators found the arteries of the tea drinkers were better able to expand and contract with the body's blood flow needs compared with the arteries of the water drinkers. |

| Diagnose |
| Black tea has heart health benefits. The study does not directly prove that tea can prevent cardiovascular disease. The writers speculate that flavonoids in tea are what help the artery walls stay healthy. The results are regarded as important but not anywhere near a guarantee that black tea drinkers will live longer. |
