During the late 1970’s wounds and ulcers were successfully treated with low-pow-er laser light by Professor Endre Mester. Márta Fenyő with her coinventors discov-ered that from among the characteristic attributes of the laser light the Polari-zation was responsible for the biostim-ulation, consequently for the healing of refractory wounds and ulcers.That is how their invention and Patent “A method and equipment for healing wounds and injuries on the body surface”, in other words: the Polarized Light Therapy was born.Márta Fenyő and her research team discovered the stimulative effect of the polarized light on all living biolog-ical systems, including the significant vigoration of the self-healing abilities of the human body, when used in hu-man therapy. This is explained mainly by the effects of the polarized light on the regeneration, revitalization and harmonization of the cell functions.Polarized Light Therapy brought re-sults also in the treatment of chronic diseases such as ulcers, acne, other chronic skin diseases and sports injuries.Prompt and spectacular results were achieved in the Polarized Light Ther-apy of operation scars, burns, head-ache, rheumatic and arthritic prob-lems.Low-intensity Linearly Polarized Light emitted in a broad spectrum has re-cently brought a new breakthrough in healing.In most cases the duration of treat-ments of restricted areas on the skin surface is in the 2 – 30 minutes range. In cases when extensive areas need to be treated, the entire area is scanned by the light beam, which obviously requires a longer time.In the year 2004 Márta Fenyő invent-ed and made protected the technol-ogy of the Polarized Light emitting light source built of LED-s, which ena-bled to construct medical equipments having light emitting surfaces of any size as well as of any shape.This technology made it possible to build medical devices being able to treat very small surfaces (e.g. one cm2), as well as large surfaces, being suitable to treat the entire body sur-face with the biostimulating and heal-ing agent: the Polarized Light.


Polarized light significantly enhances the activity of the immune-competent cells, stabilizes the cell membrane of the red blood cells and enhances their ability to bind, retain and deliver extra amount of oxygen.The treatment using polarized light significantly stimulates the activity of T-lymphocytes being responsible for recognizing and defeating mil-lions of faulty cells produced minute by minute in the human body that subsequently become responsible for serious illnesses and malignant defor-mations.Thereby this treatment can prevent more or less serious illnesses as well as it can facilitate and accelerate the recovery from protracted illnesses. Through the enhanced ability of the red blood cells to bind, retain and deliver extra amount of oxygen more vital oxygen becomes available for the cells as it was proven in a research work accomplished at the beginning of the 1980’s by Márta Fenyő and Professor Imre Lengyel, Head physi-cian of the Laboratory at the National Institute for Vascular Surgery.


The electromagnetic spectrum in-volves a broad scale of different wavelenghts, starting with the very short Ultraviolet (UV) till the longer, near Infrared (IR) wavelengths.The Polarized Light Therapy (PLT) utilizes the visible and near IR wave-lengths in course of the treatment.The penetration depth into the skin depends on the given wavelength, so it is different in the case of each wavelength.


Earlier research projects proved that wounds and chronic ulcers treated with polarized light started to heal. Polarized light stimulates the self-defence mecha-nisms of the body. It was found that the cellular defence was significantly intensi-fied following the light therapy.After the treatment using polarized light the white blood cells (neutrophil granulo-cytes) became more active: they phago-lized most of the bacteria being in the intercellular space.Beforehand the intercellular bacteria hin-dered highly the wound healing process.The microscopic image made in the course of the investigations proved that following the polarized light treatment the number of white blood cells – differ-ing from the neutrophyl granulocytes, and being the representatives of a higher degree of the immune protection, such as lymphocytes, monocytes and eosinophil cells – significantly increased in the smear which was microscopically examined. Apart from the cellular defence also the humoral defence was stimulated. The immuno-electrophoresis of the sample of the wound exudate taken after one single treatment unquestionably proved the sig-nificant increase of the absolute amount of eight sorts of vital immunoglobulines. Polarized light raised the protection of the human organism to a higher level – explains Márta Fenyő about her research.Owing to the results of the later research works the stimulating effect of the po-larized light on the immune system was repeatedly proven in laboratory tests in vitro and in vivo as well: it was shown that polarized light stimulates the activity of the T-lymphocytes in the blood.


What is the Polarized Light? How to Produce it?The beam emitted from a light source contains light waves oscillating in all di-rections of the space. The polarizing filter placed directly into the light beam per-mits the passing through only for those components of the light beam which oscillate in a single privileged direction of the space.The Effect of Polarized Light onto the Lipid BilayerThe waves of the polarized light travel in a preferred plane of the space. Accord-ing to the biophysical model developed by the inventor, Marta Fenyő and her research team the electromagnetic field oscillating in this determined plane slight-ly reorganizes the polar heads of the lipid bilayer of the cell membrane. By reaching a higher energy level, the cell membrane becomes better ordered.This minor structural change results in significant biological effects due to the amplifier role of the cell membrane; it can affect the fluidity and permeability of the membrane, the movements of proteins tightly bound to the membrane, the meta-bolic and transport processes of the cell.There is a tight link between the lipid bi-layer building up the cell membrane and the proteins bound to it. The membrane has the ability to transmit energy from the realignment of polar heads induced by polarized light towards the proteins that influence virtually all processes associated with the cell activities, like energy production of the cells, immune process-es, enzyme reactions, including also the active and passive transport processes.The cell membrane plays a prominent biochemical role, therefore the confor-mation change induced by the polarized light can influence significant biochemical processes, including recognition process-es (anti-bodies, hormones), energy trans-fer and transformation (such as oxidative phosphorylation) and information trans-fer (neurotransmitter).Furthermore, the polarized light enhanc-es the ability of the red blood cells to bind, retain and deliver more oxygen, sta-bilizes the membrane of the erythrocytes and thereby it enhances the stability of the red blood cells in anoxic environment.It enhances blood circulation; therefore the increased amount of oxygen reaches cells, organs and systems faster. Investi-gations carried out on various biological model systems proved that polarized light promotes the self-defence ability: it stimulates the immune system, promotes the regenerative processes in the entire organism, thereby assists also the wound healing.Our practical experiences gathered so far show that Polarized Light has a direct beneficial effect on nerve endings, en-ergy paths and nerve tissues, it eases or terminates pain.Based on the knowledge basis – referred to above – the conclusion can be drawn: Polarized Light Treatment normalizes and harmonizes the off-balance biological processes.
