Tea Mail – November 2003
The Big Health News in October
October’s most notable green tea news report was undoubtedly the American Association for Cancer Research’s second annual international conference on Frontiers in Cancer Prevention Research, in Phoenix, Arizona. Four research papers were presented, supporting the evidence that green tea is useful in fighting certain types of cancer, in addition to lowering cholesterol, preventing heart disease, boosting oral hygiene and possibly aiding in weight loss. Drinking just two cups, but probably more like four cups a day of green tea may retard the growth of certain tumor cells, researchers agreed.
Dr CS Yang from Rutgers University, N.J, said “laboratory studies have suggested that green tea consumption may produce many health benefits, including the prevention of cancer”, and added that “research is now showing how this novel chemopreventive agent might work at the molecular level and in the human population.”
Iman Hakim, a researcher at the University of Arizona Cancer Center, showed that cigarette smokers who drank four cups a day of decaffeinated green tea for four months cut the cellular damage caused by cigarettes. “What we found was significant,” she said, referring to tests done on the urine of the 118 smokers in the study.
Study shows tea leads to cancer prevention
Elvira DeMejia, assistant professor in food science and human nutrition, headed the research. The experiment was conducted over a period of more than nine months on two groups of rats. Both groups were given a carcinogen that would cause liver cancer. The rats in group one were the control group and drank only water and those in group two only drank fresh green tea.
At the end of the study, the rats in group one had cancer tumors in the liver, whereas the rats in group two had no tumors, DeMejia said. She is continuing the research to find specifically what mechanism in the tea is preventing the cancer. “Green tea is excellent,” said DeMejia, because it has more antioxidants. She drinks green tea or black tea every day.
Green Tea may slow down HIV
“The T-cell is the sparkplug of the immune system,” said Dr. William Shearer of Baylor College of Medicine in Houston, who is doing a follow-up study on EGCG. “The HIV virus sticks to it and kills it. That’s what causes the trouble. “Shearer said the finding could open the door to using EGCG to augment the drug cocktail that AIDS patients take.
Green tea is made up of antioxidants called catechins, the most abundant of which is EGCG, or epigallocatechin gallate. The study was published in the November edition of the Journal of Allergy and Clinical Immunology.
Green tea could protect against cancer
Green tea could have specific effects against cancer cells, according to a new study. The health benefits of green tea have long been promoted – from lowering cholesterol from fighting infection. Now researchers at Menlo Park, California, reveal how synthesized analogs of the active ingredients of green tea can react with cancer cells.
The main ingredient of green tea is epigallocatechin-3-gallate (EGCG) which has already been linked with reduced risk of breast, pancreatic, colon, esophageal and lung cancers in humans.

More fantastic Seven Cups teas to be released in December
Exciting news from Seven Cups, as three new teas are being added to the current range, and more are promised soon! The new varieties, all of which are personal favorites of the Seven Cups team, will be available to buy on this website in 2 ounce, 1/4 pound, 1/2 pound and 1 pound, foil-fresh resealable packs. And look out for more special teas from Seven Cups over the coming months, including our first Puer (or Puerh) teas.
The first new variety is Organic Gunpowder Green Tea, which is gently steamed after picking and has a well rounded, full-bodied taste.
We are especially proud to announce two more new varieties, which are our first Oolong teas: Gold Tieguanyin Oolong Tea and Monkey Picked Tieguanyin Oolong Tea. All teas come from the same plant, Camillia Sinensis, but Oolong differs from green tea in that it is partially fermented (green tea is unfermented, black tea is fully fermented). Oolong teas have some of the qualities of both black and green teas, and ours are beautifully fragrant and full bodied, with a sweet, fruity aroma.
