Helicobacter pylori is a Gram-negative, rod-shaped bacterium with an ability to colonise the gastric pylorus. It is estimated that more than half of the human population may be carriers of this pathogen. Unfortunately, the collected data concerning H. pylori infections is inaccurate as the symptoms occur only in 20% of people infected. The presence of the bacteria may lead to inflammation, stomach ulcers, or even cancer. In the cases of confirmed infection, the treatment usually involves a so called “triple therapy” with a proton-pump inhibitor and antibiotics. However, a decrease in the effectiveness of this therapy is observed as a result of increasing antibiotic resistance in bacteria. New solutions are being researched that could both help in the treatment of H. pylori infections and prevent the spread of the pathogen. Numerous scientific studies confirm that the use of plant-based products can be a good addition to the treatment of various infections. Phytotherapy is a science-based medical practice that uses the knowledge about active compounds naturally occurring in plants, in order to improve overall health. From existing research, it is known that the consumption of certain plant-derived products, for example olive oil and green tea, can lead to H. pylori eradication. On the other hand, licorice can be used to support the classic treatment method by increasing the eradication rate of the pathogen. Plants with anti-H. pylori properties include: cinnamon, cranberry, oregano, aloe vera and many others. The aim of this work is to review literature that is focused on a potential use of phytotherapy to support the treatment, combat, or prevent infections caused by H. pylori.
