The real cost of using Rife vs the cost of NOT using it! Same for zappers.
Rife machines, especially the best, can be quite expensive, some costing as much as $6000 US or more. On the other hand, there are some helpful solutions that cost below $500 US. Some minimal zappers can be found for as low as $10 to $15 US.
What is the cost of suffering from something such as Lyme Disease? How about EBV? Hepatitis B? HIV? Any other virus or other microbe? Especially when one suffers from these things for several years and allopathic medicine fails?
Would it not be worth spending $30 to 100 just to stop a cold or the flu 1 time? Would it not be worth a lot not to spend several days in bed sick?
Just because modern medicine does not offer or approve of something, does not mean that it does not help.
In fact, the better that something is at stopping you from spending money on medicine, the more that they will spend trying to keep you from using it or even knowing about it.
