Green tea may protect the bladder from becoming inflamed
May 21, 2007 -- Herbal agents could be used to treat inflammatory bladder diseases,
according to a preliminary study that looked at the ability of green
tea to protect bladder cells from inflammation. The University of
Pittsburgh School of Medicine study, being presented at the annual
meeting of the American Urological Association (AUA) in Anaheim,
Calif., found that components of green tea protected bladder cells from
damage in culture. The study is Abstract 299 in the AUA proceedings.
"We discovered that catechins found in green tea protected both normal and cancerous bladder cells from inflammation when we exposed the cells to hydrogen peroxide," said Michael B. Chancellor, M.D., professor of urology and gynecology at the University of Pittsburgh School of Medicine. "Although further studies are needed, these results indicate herbal supplements from green tea could be a treatment option for various bladder conditions that are caused by injury or inflammation."
In the study, normal and cancerous bladder cells were exposed to two major catechin components of green tea, epigallocatechin gallate (EGCG) and epicatechin gallate (ECG), for 23 hours. Both significantly protected cell lines from exposure to hydrogen peroxide, which damages or kills cells. The concentrations of EGCG and ECG used in the study were at levels that may be achieved through dietary intake.
