EGCG from Green Tea helps protect lung tissue from cigarette smoke

Cigarette smoke causes inflammation in the lungs lining leading to changes in cells that triggers cancer. EGCG from Green Tea is a powerful antiinflammatory that inhibits the proliferation of and causing the destruction of cancer cells without hurting healthy cells. In this study normal human bronchial epithelial cells were pretreated with EGCG. This prevented the smoke from causing improper cell division and NF-KappaB, an immune system chemical that protects cancer cells from destruction was inhibited by EGCG. EGCH also inhibited enzymes (MMP) that allow cancer to spread. EGCG had anticancer and antiinflammatory activity in lung tissue protecting it from carcinogenic changes caused by cigarette smoke. The study was performed at the Department of Dermatology, University of Wisconsin in Madison and is published in the July 24th 2006 issue of the journal Oncogene.
