Green tea and green tea extract as a protective agent used in liver transplant operations and cancer-fighter. Seems epigallocatechin-3-gallate (EGCG) -- a green tea extract -- may improve the condition of patients suffering from chronic lymphocytic leukemia (CLL).
Although researchers weren't sure what constitute a safe, effective dose, EGCG-rich green tea extract contained in over-the counter products certainly improved the condition of four chronic leukemia patients. (These same researchers also found ECGC killed leukemia cells taken from CLL patients last year.)
CLL is different than other forms of leukemia in that it progress more slowly than acute leukemia, and it touches as many as 15,000 Americans every year. Some patients live with this condition for decades without treatment, while others require immediate care.
The trick about drinking green tea: Be careful that the tea you're drinking doesn't contain high levels of fluoride.
