Wrong move I think, she should have used it CONTINOUSLY for 3 months then dropped down after that. This is what Bob Beck tells people to do. During those 3 weeks shes giving time for Viral counts to rise. Tell her to keep on going with it till she is happy with the results. A Blood Electrification unit is excellent but it cant do the body like a zapper, its effects are just on the pulse points area utilised and the blood.
The Colloidal Silver is another excellent idea but your doseage is far to low. She should also make sure her spoon is not Metal as this could effect its potency. A dosages of 200ml 5ppm or higher is suggested. This is not high at all!
If she follows this guideline above she will she a very big difference. The blood electrification unit should be used for 2 hours a day until results are gotten. The Singlet Oxygenation way is another great example and the combination of these is a real Lennox Lewis knockout system. She could also try herbs Olive Leaf, Burdock Root.
