frequencies?

As I just read a bit of a recent post by Jessesmom in parasupport I now have questions. I have built a zapper identical to that which is Dr. Clark gives instructions for in her first book. While at the end of the book she gives a list of frequecies she has found for each thing listed. She also stated that with the model she instructed the building of there was no need for the seperate frequecies because with the 9V power supply for what ever reason it got them all. Does this mean I do not need to worry about all the bacteria, fungi, viruses as long as I use it the three consecutive times as Dr. Clark indicated. Well at least not worry other than getting rid of the toxins all these things release.
