Helicobacter Pylori Bacteria And Green Tea Research
Researchers have examined many substances that may prevent this adhesion. One of the strong, yet safe, effective substances are polysaccharides (natural complex carbohydrates) in green tea extract. Using a hot water extract of Camellia sinensis (green tea) polysaccharides without the antioxidant catechins, scientists found that it strongly inhibited adhesion not only with Helicobacter pylori bacteria, but also with P. acnes, and Staphylococcus aureus. It showed no inhibition or adverse effects with beneficial bacteria like Lactobacillus acidophilus or commensal bacteria (Lee, In vitro anti-adhesive activity of green tea extract against pathogen adhesion, Phytotherapy Research, April 2009). Other research has found Camellia sinensis polysaccharides to be more effective than Panax ginseng or Artemisia capillaris (Lee, Inhibition of pathogenic bacterial adhesion by acidic polysaccharide from green tea (Camellia sinensis), Journal Agriculture Food Chemistry, November 2006). Preventing the adhesion and colonization of this bacterial infection is extremely important worldwide as it affects about half the world’s population. H. pylori infections are strongly associated with chronic gastritis, peptic ulcers, and the development of stomach cancer.
