The use of antibiotics to control Helicobacter pylori virulence has led, inevitably, to these bacteria developing antibiotic resistance.
To find new ways of reducing this infection without antibiotics, researchers are looking at food and plant-based solutions.
One study tested 77 plant samples against an enzyme called urease, necessary for this bacterial infection to colonize the stomach and intestines.
While both tea and rosemary herbal extracts were effective, the most powerful inhibitor of bacterial urease were the catechins in green tea extract.
In addition, animal testing showed that Helicobacter pylori virulence and infection was increasingly suppressed as the dietary green tea intake was increased, in a dose-dependent manner (Matsubara, Suppression of Helicobacter pylori-induced gastritis by green tea extract in Mongolian gerbils, Biochem Biophys Res Commun, October 2003).
H. pylori is a dangerous gatric and intestinal infection, contributing to chronic gastritis, peptic ulcers, and gastric cancer.
It is also widespread, affecting about half the world’s population.
