Dandelion belongs to the herbal plant, which has the effect of clearing heat and detoxification, but there is no scientific experiment to prove that it can kill Helicobacter pylori alone. H. pylori is a bacterium that exists in the stomach, infecting the body usually leads to gastritis, and since there is no specific drug that can kill it alone, the standard triple therapy and quadruple therapy are mainly used in clinical practice. And although dandelion has a variety of nutrients, one of the components may have some effect on inhibiting and killing H. pylori, but its proportion may be small, a single dandelion, the treatment of H. pylori infection effect is not obvious. Therefore, patients with H. pylori infection can choose triple therapy, that is, two antibiotics plus a proton pump inhibitor, if the effect is not good, you can add a gastric mucosal protective agent, that is, quadruple therapy, to effective anti-H. pylori treatment.
