I would just a small reflexion to "returning immune power".
What normal zapping do is killing unwanted microorganism in Thymus , bone narrow etc. it gives the immun power increased opportunities to fight viruses, toxins etc.
But what is essentiell is that
in order to get a fully working immune defence u have to eliminate all toxins , solvents etc. After that u even might have to erase the "memory in the water". Yes, water have a memory so even if the substance is gone the magnetic field of the harmful substances might still be there.
I have found out that zappers with teslas mobil coil do the erasing work if you are zapping. It could take some time but it works. first u have to clean your body from toxins.
