Helicobacter pylori is a common bacterial species that infects the human stomach and is a major cause of gastritis, peptic ulcer disease, and stomach cancer. The effectiveness of standard triple therapy for H. pylori eradication has decreased due to increasing antibiotic resistance. As a result, there is a need for alternative treatment approaches such as phytotherapy. The aim of this study was to investigate the in vitro activity of a patented blend of plant extracts from chamomile flowers, coneflower herbs, peppermint leaves, and thyme herbs, known as H. pylori tea against H. pylori. The study was conducted at the Department of Pharmaceutical Microbiology with Laboratory for Microbiological Diagnostics and the Department of Pharmacognosy with Medicinal Plant Unit at the Medical University of Lublin in Poland.
The product was prepared by macerating the plant extracts in various solvents and the minimum inhibitory concentrations (MICs) were determined using the microdilution broth method. The solvents used were ethyl acetate, ethanol 99.8%, and 70% aqueous ethanol.
The MIC values of the H.pylori natural treatment tea blend against H. pylori were as follows: the blend demonstrated activity with MIC values of 31.3-125 µg/ml, depending on the solvent used. The most active extracts were those obtained with ethyl acetate or ethanol 99.8%, with MIC values ranging from 15.6-62.5 µg/ml. The lowest activity was observed for the extract obtained with 70% aqueous ethanol, with MIC values ranging from 62.5-250 µg/ml.
The results of this study indicate that the blend has promising in vitro activity against H. pylori. The most active extracts were those obtained with ethyl acetate or ethanol 99.8%. These results are similar to those of the essential oil components bisabolol, menthol, and thymol. Further studies are needed to confirm the activity of this patented blend against clinical H. pylori isolates and to investigate possible mechanisms of action.
The patented “H. pylori tea” blend, made from chamomile flowers, coneflower herbs, peppermint leaves, and thyme herbs, shows promising in vitro activity against H. pylori and has potential for use as an adjuvant agent in H. pylori infection treatment or prevention.
