I have only taken the oregano drops a few days but so far it seems to be working extremely well. I would recommend the pure oregano for any kind of infection. Very good product!!!! I also read about the sputnik on MH:s website. I bought the sputnik from the Irish website and it worked pretty well the first round,(you are supposed to use it three times before the battery dies) the second time there was almost no electrical current left, so don't think the parasites got to scared of that one, and no current at all left for a third time. So I'm guessing he's right about them using them all over again. I was constipated so it took too long to get the sputnik through the system, but there's no way in hell it was lasting for 700 hours if that's the supposed time. Mine only lasted about 120-170 hours, but the first time it was working well!
