This first study found that the administration of oregano oil (oreganum vulgare) consumed orally for 6 weeks was effective at curing enteric (intestinal) parasite infections in humans. Fourteen participants were used in this study all of whom tested positive for the enteric parasites Blastocystis hominis, Entamoeba hartmanni, and Endolimax nana. The authors report that: “there was complete disappearance of Entamoeba hartmanni (four cases), Endolimax nana (one case), and Blastocystis hominis (eight cases). Also, Blastocystis hominis scores declined in three additional cases. Gastrointestinal symptoms improved in seven of the 11 patients who had tested positive for Blastocystis hominis.” This paper is important because it establishes the antiparasitic properties of oregano in humans.
