I drink green tea almost every day. I thought I would pass this along.

A component of green tea helps kill cells of B-cell chronic lymphocytic leukemia (CLL), the second most common leukemia in American adults, according to new research.

Mayo Clinic researchers found that the component, called epigallocatechin-3-gallate (EGCG), destroys leukemia cells by interrupting the communication signals they need to survive. The research appears online in the journal Blood.

CLL is most often diagnosed in people in their mid-to-late 60s. Chemotherapy is used to treat the most severe cases, but there is no cure for CLL.

In this study, the Mayo scientists found that EGCG prompted leukemia cells to die in eight of 10 patient samples tested in a laboratory.

"We're continuing to look for therapeutic agents that are nontoxic to the patient but kill cancer cells, and this finding with EGCG is an excellent start," study leader Dr. Neil E. Kay said in a prepared statement. "Understanding this mechanism and getting these positive early results gives us a lot to work with in terms of offering patients with this disease more effective, easily tolerated therapies earlier."
