Eating garlic cannot kill H. pylori, which is a kind of anaerobic bacteria, also known as microaerobic bacteria. This bacteria can only be completely killed by giving amoxicillin, clarithromycin, metronidazole, etc. Eating garlic does not have any effect on this bacteria. H. pylori is often parasitic in the pylorus of the stomach, sometimes in the form of spirals and sometimes in the form of rods, hence the name H. pylori. Usually a carbon 13 or carbon 14 breath test is required, and if the DPM is greater than normal, anti-H. pylori medication is needed. Gastric triplet or quadruplet drugs are commonly used in clinical practice, usually for two weeks of treatment, and then the carbon 13 or carbon 14 breath test will be repeated after a month or so of discontinuation.
