For most systemic infections I'd recommend the combo Beck approach ( blood electrification and magnetic pulsing ) because of its simplicity, lower cost, and effectiveness (keeps them from reproducing) on all virus and bacteria circulating in the blood. Our best overall combo for all ailments is a Microbe Electrifier and the Maxi-Pulser (or OMF Generator if there is a localized bacterial infection) since with these two you have full antimicrobial capabilities. Below I list common ailments and what approach I feel is best for their treatment although either approach is often equally effective. "LT" is short for Localized Treatment (at the site of the problem), and "ST" is short for Systemic Treatment (whole body treatment with blood electrification and whole body Pulsing).

Allergies - Beck units (ST)
AIDS - Beck units (ST)
bacterial infection, localized - OMF Generator
bacterial infection, systemic - Beck units (ST)
Cancer - Beck units (ST). also OMF Generator (LT if localized and close to skin)
Candida yeast infection (intestinal or vaginal) - OMF Generator
Chronic Fatigue Immune Dysfunction Syndrome - Beck units and Maxi-Pulser (ST)
colds - Beck units (ST)
flu - Beck units (ST)
Fibromyalgia - Beck units (ST)
fungus - OMF Generator (LT)
Gastritis/Ulcers (H. Pylori bacteria) - Microbe Electrifier  (LT)
Hepatitis - Beck units (LT, ST)
Herpes - OMF Generator and Microbe Electrifier (LT)
Kidney infections - OMF Generator
Lymes disease - Beck units (ST)
Lung/throat/sinus infections - OMF Generator (LT) used every hour
Mycoplasma Infection - Beck units (ST)
Parasites - Anti-Parasite Zapper (ST with pad electrodes)
Sinusitis - OMF Generator
Sexually Transmitted Disease (infection) - Microbe Electrifier and OMF Generator (LT). Only OMF Generator is needed if it's bacterial. (Pulse 100 times in each of 3 locations twice a day for 2-3 weeks. Email me for more details.) If it's a viral infection then blood electrification is needed to disable viruses that are scattered into the bloodstream.
Urinary tract infection - OMF Generator
