|An H. pylori infection is not exactly a death sentence, but it can still have nasty consequences.|
But cancer is only the "worst case" scenario, when it comes to the potential (ill) health effects of being infected with H. pylori.
The Helicobacter pylori bacterium has also been associated with in cases of chronic gastritis, functional dyspepsia, peptic or duodenal ulcers, and cancer or gastric lymphomas.
"Because it can survive in acidic environments, it remains intact in the stomach and promotes the destruction of the gastric mucosa. This makes the organ sensitive and vulnerable to triggering of ulcerative lesions and blocks the sterilization of food, producing failures in the digestion process." (Bonifácio. 2014)Atrophic gastritis, which is a common consequence of rampant H. pylori infections, may cause pernicious anemia because it interferes with the absorption of vitamin B12 from food. The symptoms of gastritis in general are burning, abdominal pain, loss of appetite, nausea, vomiting, feeling of satiety and gastrointestinal bleeding.
One question that arises is: How likely is it that you are infected?
With worldwide prevalence estimated at between 50 and 90%, this type of cancer frequently occurs in developing countries. And one of the most comprehensive reviews of the literature confirms, the answer to this question may well depend on where you live.

How is H. pylori transmitted? Laboratory studies have yielded evidence in favor of both faecal-oral and oral-oral pathways. However, a role for either waterborne or zoonotic transmission has not been ruled out. Overall, "the failure of investigations to single out a mode of transmission for H. pylori signals the possibility of multiple transmission pathways." (Goodman. 1995)A classic, pharmacological "H. pylori" eradication scheme that would of which recent studies show that it is more effective if a metronidazole-based therapy is chosen over the standard clarithromycin-based therapy (Nishizawa. 2014), is yet something you should only contemplate if you have actually been diagnosed with the nasty gram-negative, microaerophilic bacterium. If you only suspect being infected or want to reduce your risk of being affected, the following natural H. pylori treatments are certainly preferable to the nitroimidazole antibiotic medication metronidazole:
Feijoa sellowiana (O.Berg) is one of the natural anti-H. pylori agent (Basile. 2010)
- Leaves of Strychnos pseudoquina ST. HIL. (Loganiaceae) or rather a methanolic extract from these leaves which have been used traditionally as malaria treatment has been shown to be effective in a rodent study by Silva et al. (2005).
- Chamomille or more specifically an extract from the inflorence of the camomille flower (Cogo. 2010).
- Achiote (Bixa orellana) or rather a tincture that's made from the seeds of this shrub or small tree originating from the tropical region of the Americas (Cogo. 2010).
- Green Yerba mate leaves are another effective H. pylori treatment as Schubert et al. point out in a 2006 paper. Whether drinking mate tea will do the same, has not been established, though.
Maybe H. pylori is not always bad!? As strange as it may sound, some scientists argue that the contemporary evidence that "with modern life, for probably the first time in human history, there are large numbers of noncolonized persons" and that this decrease in H. pylori infections was associated with an increase in gastroesophageal reflux (GERD), Barrett's esophagus, and adenocarcinomas of the gastric cardia and lower esophagus. These diseases are not directly related to H. pylori, but "colonization with cag+ H. pylori strains appears protective against these diseases." Accordingly, the authors of one of the more recent papers elaborating on this hypothesis conclude: "[I]n the 21st century, the continuing decline in H. pylori may lead to the disappearance of duodenal ulcers and distal gastric cancers and toward a marked increase in GERD, Barrett's esophagus, and esophageal adenocarcinoma." (Blaser. 1999)
- Garlic extracts are another of the better-known H. pylori treatments (Cellini. 1996)
- Pistacios, or rather the mastic gum from Pistacia lentiscus (L.) var. chia (Duham) has been found to inhibit H. pylori growth by Paraschos et al. (2007).
- Malva sylvestris inflorences and leaves have been shown to inhibit the growth of H. pylori by Buffon et al. (2001)
- False rubarb, aka Rheum rhaponticum roots have been reported to be effective H. pylori killers (Cogo. 2010).
- Pomegranate peels exhibit anti-H. pylori activity, as well (Hajimahmoodi. 2011).
|Table 2: Anti-Helicobacter pylori activity of essential oils (Bonifácio. 2014)|
As you can see in Table 1 the major problem is that in vivo studies, i.e. studies in which the oil was tested in intact organisms, in the case of the essential oil from Cymbopogon aka lemongrass the anti-H. pylori effects were observed in vivo, as well (in a mouse study by Ohno et al. (2003), to be precise).
Against that background it remains to be seen if any of the previously mentioned oils, fruits, plants and plant extracts are "strong" enough to eradicate a rampant H. pylori infection in a living human being. What appears to be likely, though, is that they could prevent it from becoming "rampant" in the first place.
