She should use a blood electrifier with a higher frequency (such as 10 hertz) so that the drugs she's taking won't toxify the blood cells. Keep in mind that both ozone and Colloidal Silver have a dark side. Ozone gives you free oxygen which is a free radical which can damage healthy cells as well as microbes. And Colloidal Silver can rapidly accumulate in the body to dangerous levels. So don't take it for more than a week at low doses.
A Magnetic Pulser (such as what Sota Instruments sells) is useful and has no dark side.
