The Violet Ray was originally
developed by the famous scientist Nikola Tesla. Tesla
was successfully experimenting on disease and
rejuvenation with ozone in the late 1800s and early
1900s. In the 20s and 30s, Oxygen-Zone Therapy was used
in hospitals, clinics and sanitariums. In the second
half of the 20th century, pharmaceutical companies
started disparaging all electro-therapies as
drug-oriented medicine was taking off under the Flexner
Report which banned everthing from being taught in Medical Schools
besides deadly allopathy`.
Tesla had a hunch that, since his high-potential, his currents could be passed into the body harmlessly, "these currents might lend themselves to electrotherapeutic uses." He experimented upon himself. When Tesla was struck down in the streets by a New York taxi, he didn’t deliver himself over to the medicals but dragged himself up to his hotel room where, in seclusion and with the help of his own electrotherapy, he recovered from his fractures and contusions. He never patented in electrotherapy but in 1891 began publishing his observations in technical journals, and seven years later we find Tesla giving a speech to the American Electro-Therapeutic Association in which he details with drawings the Violet Ray apparatus he has invented for this purpose, which included a Tesla coil.
"The vital force is not enclosed in man, but radiates within and around ... like a luminous sphere. It is a radiating essence, and in these semi-material rays, the imagination of man produces healthy or unhealthy effects. But of these invisible causes of disease popular medicine knows next to nothing. Men who are devoid of the power of spiritual perception are unable to recognize the existence of anything that cannot be seen externally. There are some who have learned so much that their learning has driven out all their common sense. Medical science may be acquired by learning, but medical wisdom is the gift of God.” Paracelsus (1493–1541)
