Attached to stomach tissue
Helicobacter pylori bacteria (h pylori) must adhere to stomach mucosal cells in order to colonize our digestive tract.
Once it is attached, it can reproduce and establish damaging, potentially lethal, infections.
The majority of infected people do not experience symptoms all the time.
Instead, this infection can cause local inflammation with intermittent stomach aches, gas, acid reflux, nausea, among other abdominal symptoms.
It is considered a type I carcinogen (Stoicov C et al, Green tea inhibits Helicobacter growth in vivo and in vitro, International Journal of Antimicrobial Agents, May 2009) and is associated with stomach or peptic cancer.
Researchers have examined many substances that may prevent this attachment or adhesion in the stomach tissue.
Green tea extract stops adhesion
One of the strong, yet safe and 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 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).
50% of the world
Preventing the adhesion and colonization of this bacterial infection is extremely important worldwide as h pylori bacteria affects about half the world’s population.
H. pylori infections are strongly associated with chronic gastritis, peptic ulcers, and the development of stomach cancer.
