Core tip:Helicobacter pylori is a bacterium that is commonly found in the stomach and is capable of causing a number of digestive problems, including ulcers and stomach cancer. Over the past few years, the efficacy of conventional therapy has decreased. However, new therapies are not commonly accepted as first-line treatments in some countries because of a lack of national validation studies. This review aimed to report studies demonstrating the effectiveness of different non-conventional therapies and comparing them with conventional triple therapy.
