Helicobacter pylori is linked to a majority of peptic ulcers and to some types of gastric cancer, and resistance of the microorganism to antibiotic treatment is now found worldwide. Virgin olive oil is an unrefined vegetable oil that contains a significant amount of phenolic compounds. Under simulated conditions, we have demonstrated that these substances can diffuse from the oil into the gastric juice and be stable for hours in this acidic environment. In vitro, they exerted a strong… 
Anti-Helicobacter pylori and urease inhibitory activities of resveratrol and red wine
Abstract There is considerable interest in alternative approaches for the eradication of Helicobacter pylori using biologically active compounds including antioxidants from a wide range of natural
Antibacterial effect of kaempferol and (−)-epicatechin on Helicobacter pylori
TLDR
The aim of this work was to evaluate the in vitro antibacterial effect of kaempferol and (−)-epicatechin, both individually and combined, on H. pylori in liquid and solid cultures and in co-cultures with AGS human gastric carcinoma cells.
Olive-Leaf Extracts Modulate Inflammation and Oxidative Stress Associated with Human H. pylori Infection
TLDR
The obtained results showed that both extracts significantly decreased interleukin-8 (IL-8) secretion and reactive oxygen species (ROS) production in human gastric AGS cells, and both extracts exhibited similar potential to decrease ROS production, showing the importance of standardizing the extract composition according to the bioactive properties.
An overview of antimicrobial resistance and the future of medicinal plants in the treatment of Helicobacter pylori infections
TLDR
The current state of H. pylori antimicrobial resistance, medicinal plant constituents ranging from extracts commonly in use, by the lay community, to substances being prospected and tested by researchers as possible substitutes to treat H.pylori infection are appraised.
Olives and Olive Oil Compounds Active Against Pathogenic Microorganisms
TLDR
It has been demonstrated that the main phenolic compound in olive brines is hydroxytyrosol, a component of the oleuropein moiety, which inhibited the growth of Lactobacillus plantarum in a model system, but its presence in the brines of both olives non-treated and treated with NaOH did not lead to an explanation for the lack of lactic acid fermentation in the former olive brine.
Effect of antimicrobial compounds from olive products on microorganisms related to health, food and agriculture
TLDR
It has been found that some salt-free solutions from table olive and olive oil production processes are rich in these antimicrobial compounds, and they can exert bactericidal and antifungal activity against phytopathogenic microorganisms.
Antimicrobial activity of phenolic compounds of wine against Campylobacter jejuni
Abstract Campylobacter jejuni is a food pathogen which causes gastrointestinal conditions with an ever-increasing incidence at a global level. The antimicrobial power of wine and its components has
Natural products and food components with anti-Helicobacter pylori activities.
TLDR
The constituents derived from nature that fight against H. pylori in the literature are reviewed and the combination of these agents actually may result in lower a dose of antibiotics.
Current knowledge on alleviating Helicobacter pylori infections through the use of some commonly known natural products: bench to bedside
TLDR
The aim of this review is to analyze the role of some well-known natural products that have been tested in clinical trials in preventing, altering, or treating H. pylori-related infections.
PHYTOTHERAPY IN THE PREVENTION AND SUPPORT OF TREATMENT OF HELICOBACTER PYLORI INFECTIONS
TLDR
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.

Resveratrol and Red Wine Extracts Inhibit the Growth of CagA+ Strains of Helicobacter pylori In Vitro
TLDR
It is demonstrated that both red wine and resveratrol inhibit the growth of H. pylori cagA+ strains in vitro and further support their role as chemopreventive agents.
Inhibition of Helicobacter pylori and Associated Urease by Oregano and Cranberry Phytochemical Synergies
TLDR
The results indicate that the synergistic contribution of oregano and cranberry phenolics may be more important for inhibition than any species-specific phenolic concentration and that the antimicrobial activity was greater in extract mixtures than in individual extracts of each species.
INHIBITION OF HELICOBACTER PYLORI BY PHENOLIC EXTRACTS OF SPROUTED PEAS (PISUM SATIVUM L.)
TLDR
The potential to use natural phenolic phytochemicals from pea sprouts to control H. pylori was found to be promising and provides a strategy and foundation to design legume phenolics as functional ingredients against H. Pylori.
Essential Oils as Components of a Diet-Based Approach to Management of Helicobacter Infection
TLDR
The results indicate that essential oils are unlikely to be efficient anti-Helicobacter agents in vivo, but their effects may not be irrelevant if one plans to use them as food additives to complement present therapies.
Suppression of Helicobacter pylori-induced gastritis by green tea extract in Mongolian gerbils.
Since urease of Helicobacter pylori is essential for its colonization, we focused attention on foodstuffs which inhibit the activity of this enzyme. Among plant-derived 77 foodstuff samples tested,
A Combination Effect of Epigallocatechin Gallate, a Major Compound of Green Tea Catechins, with Antibiotics on Helicobacter pylori Growth In Vitro
TLDR
Results indicate that green tea catechins may be a valuable therapeutic agent against H. pylori infection and general combination effect between EGCg and other antibiotics, such as MTZ and CLR, on the antibacterial activity against clinical isolates.
In Vitro and In Vivo Activities of Tea Catechins against Helicobacter pylori
TLDR
In infected Mongolian gerbils, H. pylori was eradicated in 10 to 36% of the catechin-treated animals, with significant decreases in mucosal hemorrhage and erosion, suggesting that tea catechins may have therapeutic effects on H.pylori infection.
Anti-Helicobacter pylori flavonoids from licorice extract.
TLDR
Three new isoflavonoids with a pyran ring, gancaonols A[bond]C, were isolated together with 15 known flavonoids and exhibited anti-H.
In vitro inhibition of Helicobacter pylori by extracts of thyme.
TLDR
The aqueous extract of thyme possesses a therapeutic potential which merits validation by clinical studies, and had a significant inhibitory effect on H. pylori, reducing both its growth and potent urease activity.
Comparison of the concentrations of phenolic compounds in olive oils and other plant oils: correlation with antimicrobial activity.
TLDR
Results indicate that not all oils classified as "olive oil" had similar bactericidal effects and that this bioactivity depended on their content of certain phenolic compounds.
