Drinking dandelion water does not cure H. pylori. Helicobacter pylori is a kind of bacillus with bluntly rounded ends and curved or curved shape, which can survive in human stomach without being affected by gastric acid and other factors, triggering gastritis, gastric ulcers, duodenal ulcers, gastric cancer and other diseases, leading to stomach pain, acid reflux, heartburn, nausea, vomiting, gastric distension, post-meal feeling of fullness, feeling of early satiety and other uncomfortable symptoms. The eradication of Helicobacter pylori requires a combination of drugs, commonly used antibiotics such as clarithromycin and furacilin, combined with proton pump inhibitors such as omeprazole and pantoprazole and bismuth potassium citrate, taken for 14 days, to achieve the effect of killing Helicobacter pylori and improving symptoms such as stomach pain. Dandelion water is not a drug and cannot cure H. pylori. Once infected with H. pylori, it is recommended to consult a doctor for a clear diagnosis and targeted treatment under the guidance of the doctor.
