(NaturalNews) An extract from green tea may slow the progression of the most common form of leukemia, according to a study conducted by researchers from the Mayo Clinic and presented at the annual meeting of the "American Society of Clinical Oncology."

The study was conducted on 42 patients suffering from early-stage chronic lymphocytic leukemia (CLL). Because CLL typically develops slowly with periods of remission, patients are only treated when the disease is actively spreading. None of the study participants were yet undergoing any cancer treatment, including radiation or chemotherapy.

The participants were treated with an extract of epigallocatechin galeate (EGCG), an antioxidant in the catechin family, leading to a significant drop in leukemia cell count in more than two-thirds of participants. In more than one-third of participants, the number of cancerous cells in the blood dropped by a full 20 percent. Additionally, 70 percent of patients who were suffering from enlarged lymph nodes underwent a 50 percent reduction in lymph node size.
