The May 15, 2008 issue of the American Journal of Respiratory and Critical Care Medicine published the discovery of researchers at the University of Louisville in Kentucky that the antioxidant property of green tea could help prevent the cognitive deficits associated with obstructive sleep apnea (OSA). Sleep apnea occurs when breathing is periodically interrupted during sleep, temporarily depriving the brain of oxygen. When caused by airway collapse or blockage which obstructs breathing during sleep, the condition is known as obstructive sleep apnea.
The December 15, 2007 issue of the journal Biological Psychiatry
published the results of a study conducted by Dr Baolu Zhao of the Academia
Sinica in Beijing, China and his colleagues, which found a protective effect
on the brain for green tea extract in an animal model of Parkinsons
disease. Previous research conducted by Dr Zhaos team found that tea
polyphenols, which have an antioxidant effect, were associated with an
in-vitro neuroprotective benefit.

In laboratories around the globe, green tea is sparking tremendous excitement as new health applications keep being discovered.
A large epidemiological (population-based) study in Japan has found asignificant reduction in the risk of death - especially deaths due to strokes - among people who drank five cups of green tea per day. However, the same study surprisingly found that green tea had no impact on the risk of dying of cancer. The Ohsaki National Health Insurance Cohort Study, published in the Journal of the American Medical Association in September, 2006, was begun in 1994. It eventually involved over 40,000 Japanese adults who had no prior history of stroke, coronary heart disease, or cancer.
Active Components:Catechins (polyphenols)

The Chinese have used green tea for thousands of years. Recently it was introduced onto the American natural health markets. Green tea is rich in bioflavonoids. Bioflavonoids are compounds that help fight damaging free radicals. One class of bioflavonoids, polyphenols, is especially abundant in this herb. Specifically, the catethins(polyphhenols with multiple linked ring-like structures) have extraordinary antioxidant ability, especially in the brain.
