The Erchonia cold laser uses concentric lasers at a wave length of 635nm and scrolling frequencies to allow various effects of the exposed tissue.
The bottom line is that the cold laser works like putting the proper amount of light onto a plant. Enough allows the plant to fluerish. Too much can kill it and not enough will not allow it to grow.
Here's a good example. A neuroma is an inflamed nerve- often found in the foot (Mortons Neuroma). The body tries to heal the nerve but walking and irritation doesn't allow it to heal. So it feels better for a while and then comes back. Lasers have been shown to help the tissue heal quicker and get ahead of the lesion.
The Erchonia laser has been shown to accelerate tissue healing x2. Quicker healing and you gain ground. The laser speeds the healing by doubling the activity of the ATP in the cell and by doubling the rate of cell division.
It is not a cure all but it is another treatment that is gaining notice, especially with patients that have seen great success.
