(NaturalNews) An extract made from one of the main antioxidants found in green tea may be able to slow the progression of prostate cancer, according to a study conducted by researchers from Louisiana state University and published in Cancer Prevention Research, a journal of the American Association for Cancer Research.

Researchers gave 26 prostate cancer patients between the ages of 41 and 68's four capsules of day of Polyphenon E, an extract of epigallocatechin gallate (EGCG) made by Polyphenon Pharma. EGCG is a powerful antioxidant to which many of the health benefits of green tea have been attributed. The dosage given to the participants in the study was equivalent to that acquired from drinking 12 cups of green tea per day.

After 12 weeks, the researchers found that levels of the prostate cancer markers Hepatocyte growth factor (HGF), vascular endothelial growth factor (VEGF) and prostate specific antigen (PSA) had fallen by an average of 18.9 percent, 9.9 percent and 10.4 percent, respectively, indicating a slowed progression of the disease.
