Another pioneer in the field of light therapy was Dr. Emmett Knott. In 1928 he developed
the Knott Technique of Ultraviolet Blood Irradiation. His system used ultraviolet light to irradiate a
small amount of blood that was extracted from the body and which was then returned to the body intravenously. This technique
was used to treat bacterial and viral infections as well as a range of non-healing wounds, inflammatory diseases and autoimmune
disorders. Knott's machine received "grandfather" status from the Food and Drug Administration (FDA).

Since the advent of antibiotics Western
medicine has moved away from light therapy. Because in the U.S. the pharmaceutical companies and the FDA control the field
of medicine the biggest advances in the area of development of UV light therapy have taken place in Europe, and more specifically
in Russia and Germany. You can see the range of machines developed in those areas in our database.
Since the FDA's approval of the Knott
machine the FDA has only granted two approvals to light therapy machines, the Therakos from Johnson & Johnson and the
Medfaxx. The Therakos system is used to treat cutaneous T-cell Lymphoma or CTCL which is a type of Non-Hodgkin Lymphoma (NHL).
UVA and a photosensitizing agent are used in this process. According to their website they are "actively engaged in basic
research, have an expanding program of clinical trials, and are supporting innovative independent studies within the academic
and medical community." Medfaxx is used for bactericidal management of dermatologic disorders with UVC light.
A newer company
which has developed a revolutionary concept in Light therapy is Harris Medical Resources. The Harris UV Lamp is revolutionary
in that it treats the blood sublingually using UVC light. Our company UVN America has acquired the rights to the Harris UV
Lamp device, United States patent number U.S. 7,763,059 B2. Physicians throughout the world have used this device to
treat HIV, Malaria and Hepatitis B & C. They have also been granted IRB approval for: A
Prospective Clinical Evaluation of the Harris Medical UV Lamp for the Reduction of Chronic Hepatitis C Viral RNA Load: A Phase
2 Clinical Trial (T.A.B.S. Protocol No. 2012-007).
Hopefully this kind
of treatment will be fully accepted by the medical community at large and will begin to be integrated into medical treatment
protocols all over the world. This is just the beginning for light therapy in the medical technology world. Indeed the future
is bright for light therapy.
