Between 1900 and 1930 in the USA electrotherapy was the most popular form of medical treatment by doctors and was taught in most medical schools. Then the AMA and FDA came into existence with their focus on pharmaceutical drugs to gain much money and take away the power to heal from the hands of the common man. (Back then people could buy electromedicine devices from the Sears catalog.) They had the medical schools stop teaching electromedicine by threatening to take away their AMA-accredited status. And the FDA made it illegal to sell electrical devices for the purpose of treating disease unless they approved them (ha! fat chance!). So then, little by little, electromedicine was forgotten in this country. See the electromedicine museum at http://www.electrotherapymuseum.com/. But in 1992 researchers at the Albert Einstein College of Medicine discovered that a small amount of electrical current disabled 98% of HIV-1 from being able to infect human blood cells. They used this research as the basis of a couple of medical patents, but no company ever purchased the right to use that technology to have a non-drug approach to treating AIDS. (Maybe because they were scared to counter the mob-like drug companies.) When Bob Beck, a physicist and alternative health researcher, found out about these patents he devised a simpler method of applying electricity from batteries to the blood to affect the microbes therein. Then he tested his blood electrification device against microbe-caused diseases and was generally successful. Then he started lecturing around the country and a few companies started making and selling his devices. I joined that elite group in 1997 after using those devices to rid myself of a 16 year infection of Epstein Barr Virus that caused Chronic Fatigue Immune Dysfunction Syndrome. My first customer success stories were from 2 people who had cancer. This is because there are cancer-causing viruses that these devices help eliminate. Lately I've discovered how to make tumor electrification devices based on info from scientific studies, the Chinese, and the Germans. I've supplied them to a local cancer doctor here who has used them with great success. Just look up "tumor electrification" on Google for a very enlightening mind trip.
