Why use expensive and potentially harmful antibiotics to eradicate Helicobacter pylori, when natural oils are equally effective?
Essential oil of Origanum vulgaris(oregano), containing high quantities of carvacrol, apart from exhibiting broad spectrum bactericidal activity, even against antibiotic-resistant strains, broad spectrum fungicidal activity, without any side effects, even against fluconazole resistant strains, has also antinociceptive and potent anti-inflammatory activity.
Carvacrol is highly bactericidal against H. pylori P1 and against other Helicobacter strains tested. 
No bacterial resistance has been observed.
