May have antibacterial effects against H. pylori

The stomach and small intestine are both infected by the bacterium H. pylori. It can result in stomach cancer and inflammation of the stomach lining and is the main cause of peptic ulcers. Even though the infection affects around 50% of the world's population, most people won't experience these issues. Although the exact mechanism of H. pylori transmission is unknown, experts think that contact with feces-contaminated food and drink may be a factor.

Proton-pump inhibitors, which lessen the production of stomach acid, are frequently employed in treatment plans for peptic ulcers brought on by H. pylori. Wasabi may also help heal peptic ulcers brought on by H. pylori, according to preliminary test-tube and animal research. Although promising, more human studies are required before any judgments on the impact of wasabi on H. pylori can be made.
