Look at the Mayo Clinic website

I have amazing and important news, I was pretty sick with my CLL for about 4.5 years, then doing more research, I found the Mayo Clinic website (this was in 2012). They were convinced that a lot (I take about 4100 mg per day, no side effects) of green tea extract would help a great deal. My white count in 2012 was a little over 41,000 and slowly climbing. I started taking green tea extract (Walmart and Amazon both carry it) and my flare-ups and episodes have stopped. My whitecount has since stayed around 25,000 to 28,000. I can still feel pretty bad sometimes, but it's short-lived. Once I was really sick for about 95 days. I was in charge of the payroll at a manufacturing plant, back then we had 73 employees and paid weekly, so I just sucked it up and didn't have any sick days. I am sharing this so if it just helps 1 person, please if you have CLL give green tea extract a shot, if it helped me maybe it will help you too.
