Green Tea is one of the most extensively, and successfully, researched herbs in the world today. It was first noticed several decades ago, that people involved in presenting the green tea ceremonies had remarkably low incidence of cancer. Hundreds of studies later, we now know that green tea, and in fact all tea (Camellia sinensis) as a wide range of beneficial properties for reducing risks of cancer, heart disease and liver disease, plus antioxidant properties, benefits for the skin and much more. Here is some of the recent research on tea and its antioxidant polyphenols.

Rationale: The intermittent hypoxia (IH) that characterizes sleep disordered breathing impairs spatial learning and increases NADPH oxidase activity and oxidative stress in rodents. We hypothesized that green tea catechin polyphenols (GTPs) may attenuate IHinduced neurobehavioral deficits by reducing IH-induced NADPH oxidase expression, lipid peroxidation, and inflammation.
Conclusions: Oral GTP attenuates IH-induced spatial learning deficits and mitigates IH-induced oxidative stress through multiple beneficial effects on oxidant pathways. Because oxidative processes underlie neurocognitive deficits associated with IH, the potential therapeutic role of GTP in sleep-disordered breathing deserves further exploration.
