Hi @valeriewiegand. I moved your question about the potential positive effects of green tea on CLL to this existing discussion:
– Chronic Lymphocytic Leukemia: Mayo study on green tea extract (EGCG) https://connect.mayoclinic.org/discussion/chronic-lyphocetic-leukemia/

I did this so you can read the previous posts and connect with members like @aprilb @boocat @minnesotajim @nancyal and others.

In short, a green tea extract has shown some promise in initial clinical trials for treating chronic lymphocytic leukemia. Laboratory research determined that a compound in green tea extract, called EGCG, can kill chronic lymphocytic leukemia cells. A study of people with early-stage chronic lymphocytic leukemia found that EGCG in pill form reduced some signs of the disease. But green tea trials haven't been conclusive, and this subject requires more study before doctors can agree on the merits of this treatment.

@valeriewiegand I do not have CLL, but am dealing with multiple myeloma. Here is an article from Mount Sinai about teas and how they interact with different conditions. Here's betting you will find some interesting information! What do you think?
