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 approval of the Knott machine the FDA
has only granted two approvals to light therapy machines, the Therakos from Johnson and 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." the Medfaxx is used for bactericidal management of dermatologic disorders with UVC
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 physicians throughout the world have used this device to treat HIV, Malaria and Hepatitis B & C. They
have also been granted IRB approval for the study of the treatment of Temporomandibular Joint Pain and Hepatitis C.
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 the world over. This is just
the beginning for light therapy as the floodgates have been opened and the sky's the limit for this technology. The future
is bright indeed for light therapy.
