Cold Laser is light frequency therapy. It stimulates cell reproduction and growth and therefore the healing process. It acts the opposite as an infection. An infection will invade a cell and then spread to other cells infecting the other cells. Cold laser stimulates cells and causes those cells to stimulate the cells around them into faster growth and reproduction. It is not recommended for cancer, however, there are cancer codes. It is not completely understood if these codes slow the growth of cancer cells or stimulate killer T-cells which kill cancer cells and therefore is currently contraindicated for cancer of all kinds. Dr. Pena has been very successful using cold laser therapy on patients with migraines, trigger points (scar tissue) in the muscles, tremors, insomnia, wounds, gastritis, infection, inflammation, anxiety, drug and smoking addiction, and many other ailments.
