At the very beginning of the study, 14 aromatic plants (hyssop, sage, rosemary, fennel, yarrow, tarragon, basil, juniper, wild thyme, lemon balm, lavender, mint, oregano and savory), growing in the Balkan peninsula were chosen and their essential oils were isolated.
The essential oils obtained were tested against H. pylori cultured in the laboratory.
Results showed that savory and oregano essential oils expressed the highest activity, whilst a combined mixture exhibited 4 times higher activity than individual oils. [1,2]
Since the mixture of savory and oregano essential oils had a significantly higher activity in the elimination of H. pylori than individual oils, the mixture was examined in the next phase.
