THE NATURE OF LIGHT
1 What type of light is being used? 2 Why does it work? 3 What functions of a light unit are important?
We all know that light (sunlight) is essential for all living things. Over the years the use of artificial colored light as a therapeutic aid has proved successful, but not consistent. We feel the reason for this, is that the colored lights which were used actually consisted of many frequencies.
An example is a white incandescent bulb using a red coating or filter over it. When this light is analyzed scientifically, it actually shows many frequencies of red plus traces of blue, yellow, orange and green. Current research has shown that the most effective results, in terms of using light on the body, are obtained when using a single frequency or wavelength of light. This is referred to as monochromatic light.
Sunlight itself consists not only of the visible light but ultra-violet and infra-red. In addition, each of these visible colors is not just a single wavelength, but is comprised of a range of wavelengths so that you actually have a band of color.
Green ranges from 490 nanometers to 560 nanometers. Red wavelengths of 630, 660 and 670 nanometers have been commonly used on research on the treatment of tissue. Good results also have been obtained using infra-red wavelengths at 880,940, and 950 nanometers.
Our preference is the 660 red frequencies because of its visibility and its compatibility with the cells in our body. The light should also be bright enough to penetrate deeply into the tissue. The brighter the light, the more biologically effective it will be.
The brightness should be at least 4,000 milli-candles and it could be as high as 15,000 milli-candles. So, essentially, the light should be a bright, monochromatic red color. Monochromatic means that it should contain no other color wavelength except 660 nanometers.
There are two methods to accomplish this. One, use a low powered, 2 milli-watt laser, or two, a light-emitting-diode (LED) with power up to 50 milli-watts. We prefer the LED because it is less expensive, and it is less technical to use.
It�™s also smaller, lasts longer, and is non-dangerous to the eye or any other part of the body. The LED uses non-coherent light rather than the laser�™s coherent light, so there is no way that tissue can be damaged. Non-coherent light literally means that the light is broken up or caused to be out of phase.
Coherent laser light is specifically phased to increase its strength and focusing power. The Food and Drug Administration has approved the use of low wattage lasers as long as a physician warns the patient as to the experimental nature of the device. Based upon research and observed results, we feel the use of the LED light is equal to the low power laser and in many applications it is superior.
There are a number of LED light machines available on the market today, ranging in price from hundreds to thousands of dollars. While the more expensive machines usually have more functions, these functions aren�™t always necessary to the average user. The functions include plug-in light probes, with different LED colors.
There are also adjustable brightness, adjustable pulse rates, electro-acupuncture probes and acupressure point readout meters. In addition, some are plugged into 120 volt power outlets while others use throw-away or rechargeable batteries. But when it comes down to applying the red light for a specific purpose, when you know exactly what you want to accomplish, then all the machines are essentially the same.
So our advice to the average person is to obtain an inexpensive light unit first, and then later acquire a machine with more functions, if that interests you. We also want our light unit to be able to select either a continuous or a pulse beam.
A preferable pulse rate is 250 cycles per second since this is most compatible with the body�™s nervous system. You will not be able to see this pulse rate since your eye can only see about 45 cycles per second; but, if you move the light rapidly from side to side, you can distinguish the pulses which appear as a broken light image.
PAIN RELIEF AND HEALING
Now that we have discussed the nature of the light we are using, it is time to talk about its main uses. The first feature is its ability to reduce or eliminate pain and swelling in the body (using the continuous beam).
The second feature is its ability to increase the rate of healing of diseased or damaged tissue (using the pulse beam). The light itself is not doing the healing. Rather, it is providing the necessary energy to the cells, specifically to the DNA molecules in the cells, and the cells perform their own healing.
To help visualize this process under normal conditions, picture natural sunlight entering the body and providing energy to every cell in the body. This energy must pass through pathways in order to complete the distribution of energy to the DNA molecule in each cell. These pathways are referred to as the acupuncture, acupressure or the meridian system.
The DNA in turn directs the energy to the cell membrane. When the energy is cutoff or overloaded to an area of the body, the cells in that area cease to function normally. The cutoff or overload of energy may be caused by injury, disease, infection, tension, stress, fear, guilt or any number of sources.
One way of helping to alleviate this adverse condition is to use the light to provide an energy transfusion to the distressed cell. The light can be applied by two methods. Either directly to the problem area or indirectly via those acupressure points that are connected with the problem area. These points are specifically indicated in the second section of the Practitioner's Manual.
The light�™s wave length, 660 nanometer red, plus its brightness allows it to penetrate quite deeply into the body�™s tissue. In addition, the light rays bounce off the water contained in the body tissue. This scatters the rays even deeper, and affects the surrounding cells. You can reach virtually any spot within the body directly with the light.
It is always better to apply the light in a darkened area, meaning it is not as effective if it used in a highly lit room or outside with the sun. The light is not as effective if used through clothing because clothing will deflect or change the wavelength of the light.
For direct application, hold the light probe close to or on the skin, directly over the area you wish to work on. Some people find the light more effective when they rotate the light slowly clock-wise, that is, towards the right.
Apply the light for 5-20 minutes, depending on the severity of the problem. Then, wait for 40 minutes. If the pain still persists, proceed with another treatment. Repeat this process as often as necessary until the pain is gone. Don't be scared to experiment with a variety of points on the body, you can do no harm!
Remember to use the continuous light beam for pain and swelling (activated when you turn the head and the solid light beams), and use the pulse beam for the healing of diseased or damaged tissue (activated when you turn the head a second time -you will see the light pulse for just a second but then pulses faster than the eye can see).
The continuous beam is sometimes referred to as the �œsolid beam��. Again, to help visualize what is taking place, picture the beam of light energy penetrating down to the problem cells. When there is pain, the cell walls can be pictured in a state of extreme tension.
The continuous beam provides a vibrational signal to the DNA in the cell. The DNA, in turn, instructs the walls or membranes of the cell to relax. As the cells relax, the tissue make up of those cells also relaxes. This is followed by the relaxing of the muscles and the pain subsides.
In addition, the light increases the blood circulation in the area that it penetrates. This increased circulation results in a warm, glowing feeling within the problem area which further adds to the soothing effect on the painful area.
When there is disease or damage, the cell walls can be pictured as shrunken, deformed and transparent or fading. The pulse light beam provides a stimulating, rejuvenating energy to the DNA in the cell. The DNA transmits this energy, via a protein or calcium transfer, to the cell walls and the cells transform to healthy looking solid shapes as the treatment progresses.
The energy supply which had been blocked from these cells has been replaced with the energy of the light unit and the DNA molecule now has the energy to do its normal function.
There seems to be several reasons why this particular light is so effective. The wavelength emitted by healthy cells averages between 600 and 725 nonometers, whereas unhealthy cells emit a shorter wavelength. The 660 nanometer red light is in the middle of the healthy cell wavelength range and therefore appears to be in close harmony with the cell.
This could explain why infra-red frequencies (remember the 880 and the 940 frequencies) which, although they penetrate deeper into the tissue, still have slower healing times than the red light. In addition, the DNA in the cell appears to respond much more quickly to a single frequency of light than to natural sunlight, which contains all the color frequencies.
It seems that the DNA, when it is deprived or overloaded with energy would prefer to communicate or respond to only one frequency at a time, much like your wanting to talk to one person at a time rather than simultaneously with many people, especially if you don't feel well.
The following physical problems have been either observed, reported or researched as having shown significant pain reduction when the light is applied. Headaches, ear and toothaches, tense muscles, pulled muscles, sprains, cuts, burns, back pain and arthritis pain.
Likewise, faster healing rates have been noted in physical problems like wounds, burns, psoriasis, rashes, tendonitis, herpes, torn ligaments, arthritis, circulatory conditions, organ and tissue degeneration and sinus problems. Feel free to experiment with other conditions!
The use of the red light has produced no known side effects. It does not cause any tissue damage and it cannot be over applied. At times, a temporary increase in discomfort occurs with chronic conditions. This has been noted an indicator of tissue reactivation, or detoxification, and precedes improvement.
We recommend that under no circumstances should you use this treatment in place of your normal medical treatment, simply us it as a supplement (we have to tell you that).
In 1965, when monochromatic light was first developed, the only way to produce it was with a low power or soft laser. As a result, the majority of the research since that time has dealt with the use of soft lasers.
A low-power laser differs from normal high-energy lasers in that the amount of light and energy generated is very weak. Soft lasers create an almost homeopathic stimulation of the cells whereas high energy lasers can destroy the cells (such as in laser surgery).
Recently Light-Emitting-Diodes (LED) has undergone dramatic changes. As technology has improved, LEDs have changed from being just simple �œindicator�� type lights in electronic equipment (20 milli-candle power) to today�™s ultr-bright and unique wavelength LED (15,000 milli-candle).
This has provided a safe, less costly and available alternative to the low power soft laser. An LED generally produces about 85% of the results of a foot-laser (e.g. pain relief in 7 minutes instead of 6 minutes. Today more and more research, using LEDs instead of soft lasers, is being published. The majority of soft laser research is directly applicable to the use of LED. Remember to apply the light in a darker environment for maximum effect.
THE USE OF ACUPRESSURE POINTS
As we mentioned earlier, the light may also be applied indirectly through the acupressure points to deal with both pain and healing conditions. The body consists of 12 main and 2 control meridian systems. Please refer to the Practitioner's Manual for more information.
Combinations of acupressure points from different meridians can be activated to affect a specific organ or area of the body. In addition, each of the main meridian systems, which are associated with specific organs, end at the tip of a finger or toe for easy access.
For thousands of years, Chinese acupuncture doctors have manipulated these points with needles to improve the health of their patients. In the United States, acupuncture has been accepted and integrated into our medical services. Because many people do not like the needles, a variety of acupressure has been developed, which manipulates the points with finger pressure instead of needles.
These acupressure points can also be utilized by the light probe as pathways to deliver the light energy to the desired area in the body. In fact, when the probe is pressed physically against an acupressure pint, it is accomplishing both pressure activation and light activation at the same time. Acupressures in the United States are already using the light probe as an alternative to finger pressure.
When we apply the light at acupressure points, we use the same rule that we do for direct application. This is the continuous beam to relieve or sedate the pain and swelling, and the pulse beam for healing, rejuvenation and stimulation. The light travels along the meridian pathways to the cells in that part of the body that you wish to help.
The DNA in the cells then uses the light energy in the same way as it does with direct light application. Applying light through the acupressure points has proved more effective for some ailments than the direct application.
Healing of internal organs, especially chronic conditions, deep body pains, sinus problems and arthritis are a few. We recommend using both direct and acupressure application for most problems.
The duration of treatment on acupressure points is shorter than for direct application. Thirty seconds on each point is generally sufficient if you find the right point. Make sure you press the probe into the acupressure point to take advantage of the pressure application benefits as well as the light benefits.
Remember that some like to rotate the light probe clockwise, this is, to the right, in a tight circle. Don�™t be worried that you are not on the exact spot, since the light will penetrate a wide area during the rotation. This can easily be demonstrated by holding a light probe against your finger tip. See how deeply the light penetrates and how wide it radiates? If there is an acupressure point anywhere in that lighted area, it will be affected.
Now, all that remains is to determine which acupressure points you use for a specific problem area in the body, and then how to find where they are located. In order to make this task as easy and as quick as possible, we can take advantage of the wide selection of reference books already published on the subject of acupressure and acupuncture.
You may use any book that you have ready access to, although we have compiled among the best information in our Practitioner's Reference Manual.

I've been looking at 1072nm, because that is the light wave length used in the LED Helmut used in the UK. And then I ran into the following clinical study which shows in healing herpes symplex sores -- 1072nm is twice as fast as Aclovir the normally prescribed method.

The following shows a wave length 1072nm that actually kills bacteria and virus
quote: Our studies have shown that the wavelength centred around 1072 nm is particularly effective at treating herpetic and bacterial infections, alleviating acute pain and in treating eye conditions, whilst the wavelength centred around 1268 nm is particularly effective at providing pain relief from deep muscle injury. It is of note that these two preferred wavelengths correspond to the peak emission wavelengths of a water molecule light transmission profile and thus we believe that the mechanism of action is related to water and possibly cell membranes.

Thanks. I'll look at the articles later.
I just found a ton of info. I'm going to post some of the articles every day or so in case people want to look them over.

"LASER LIGHT VS LIGHT EMITTING DIODES (LED). When this therapy reached the U.S. and Canada, both lasers and light-emitting diodes at 660 nanometers were being used. The LED diffuses; the single frequency laser does not. With this diffusion, the cell can actually be in control of the treatment and shut off the molecules when it was done.
But with the laser, the cells are no longer in control; the doctor or the practitioner applying the laser is in control. If he does it too long or with too much strength, you would not only heal the tissue, but you would start a deterioration again.
So basically, the use of light-emitting diodes eliminated the draw back of lasers, and light could be applied into such sensitive areas as the eyes and around the face. LEDs allowed this whole area to blossom into a much larger usage by average people in their homes.
Tiina Karu, Ph.D. of the Laser Technology Center in Russia, and affiliated with the University of California at Berkely, probably the top researcher in the world on the use of lasers and light emitting diodes published a study in Health and Physics Digest called "Photobiological Effects of Lasers" which discusses photobiological stimulation without laser light.

The article explains that you can do laser treatment without using laser light, by using light emitting diodes which are much safer. Since the cells are basically in control of the process, there is no way to overuse light."

"Lasers, however, have some inherent characteristics that make their use in a clinical setting problematic, including limitations in wavelength capabilities and beam width. The combined wavelengths of the light for optimal wound healing cannot be efficiently produced, the size of wounds that may be treated is limited (due to laser production of a beam of light--a fact inconsistent with treating large areas), heat production from the laser light itself can actually damage tissue, and the pinpoint beam of laser light can damage the eye. NASA developed LEDs to offer effective alternatives to lasers.
These diodes can be configured to produce multiple wavelengths, can be arranged in large, flat arrays (allowing treatment of large wounds), and produce no heat. It is also of importance to note that LED light therapy has been deemed a nonsignifucant risk by the FDA; thus, FDA approval for use of LEDs in humans for light therapy has been obtained."

"Light technology has come a long way since the innovative development of lasers more than 40 years ago. Other monochromatic light sources with narrow spectra and the same therapeutic value as lasers--if not better in some cases--are now available.
These include light emitting diodes (LEDs) and superluminous diodes (SLDs). As the name suggests, SLDs are generally brighter than LEDs; they are increasingly becoming the light source of choice for manufacturers and researchers alike.
The light source does not have to be a laser in order to have a therapeutic effect. It just has to be light of the right wavelength. Lasers, LEDs, SLDs, and other monochromatic light sources produce the same beneficial effects. Simply stated, light is light. The dose and wavelengths are critical.
At present, it is believed that appropriate doses of 600 to 1,000 nm light promote tissue repair and modulate pain."
