RESUMO
This research is based on the effect of the lemon tea concentrate whose polyphenols are powerful antioxidants. Studies have shown that they suppress free radicals in a more effective way than vitamins C or E; in some of cases, specifically in H. pylori, which generally colonizes the human stomach as a single strain with stable characteristics. Authors mention that this colonization can be stable throughout life. This bacterium is related to chronic gastritis, and although H. pylori infection is still the main cause of duodenal and gastric ulcers, the prevalence of ulcers associated with H. pylori is decreasing, while that of related ulcers with non-steroidal anti-inflammatory drugs (NSAIDs) is increasing. Much of what has been published lately about H. pylori and has focused on its important changes in the pattern of the disease and in the potential value of eradication therapy.
