EGCG from Green Tea may help anxiety

July 26, 2006

GABA is the major neuroinhibitory neurotransmitter in the brain. When GABA receptor sites are properly stimulated it induces relaxation, reduces stress, reduces anti-anxiety, and helps induce a feeling of calmness. In this study mice were fed EGCG, Green Teas most important polyphenol. It was found that EGCG at high serving sizes prevented inhibition of GABA(A) receptor sites. This allows the form of GABA function that decreases anxiety, stress, and irritability. This research was performed at the University of Montpellier II in France and is published in the July 19th, 2006 issue of the journal Brain Research.

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.

Studies show it is not the caffeine which helps decrease the risk of developing diabetes but probably the polyphenols.
