Green Tea Extract Improves Chronic Lymphocytic LeukemiaTopics: Health Issues
As we have posted in numerous previous posts, green tea is very good for your health, and has shown strong evidence of having beneficial effects in cancer, diabetes, cariovascular disease, immune function, lowering total cholesterol levels, as well as improving the ratio of good (HDL) cholesterol to bad (LDL) cholesterol, and more.
Now researchers at the Mayo Clinic in the US are reporting that they've found that it appeared to improve the condition of four patients with chronic lymphocytic leukaemia (CLL), a cancer of the lymphocytes that is the most common type of leukaemia, mainly affects people over 60, and that is rare in people under the age of 40. The exact mechanism by which green tea may fight cancer remains unclear, and may include antioxidants and other compounds acting synergistically.
The Mayo Clinic study found that EGCG (epigallocatechin gallate), a catechin found in green tea, was able to kill cancer cells that were taken from CLL patients and put in a test tube with the tea compound.
All teas (green, black, and oolong) are derived from the same plant, Camellia sinensis. The difference is in how the plucked leaves are prepared. Green tea, unlike black and oolong tea, is not fermented, so the active constituents remain unaltered in the herb.
