I bought a cheap zapper on Ebay because I did not want to spend a lot of money on something that might be a waste.
recommends using it for a total of 21 minutes per day split three times. 7/7/7. I don't do it her way.
I use my zapper all night long. I tuck the rods in the elastic of my PJ's and let er rip until morning. The reason that they kill parasites, etc. is that they get your white blood cells active. In a person that has a weakened immune system the white blood cells are not very active. They get active and hungry.
I also use a frequency generator. I can get specific numbers with that. The zapper is an additional weapon in my arsenal for the destruction of parasites
and other nasties that have taken up residence. Used in conjunction with anti parasite
herbs and thorough sanitation after Restroom activities reduces your re-contamination exposure.
In my two Liver Flushes, I have gotten uncountable numbers of dead liver flukes out. I couldn't tell that the zapper was working until I did the liver flushes.
We need all the weapons we can get our hands on to eliminate these disease causing organisims. By all means try the zapper, I'm glad I did.
