Although nowadays light sources such as LASERs (Light Amplification by Stimulated Emission of Radiation) and LEDs (Light Emitting Diodes) are largely used in several therapeutic areas, the scientific basis of their effects on biological systems still is relatively unknown by the academic community. In this study, a brief revision about effects of light on biological systems is presented. Low power light sources such as LEDs may be used as an alternative therapeutic method or be used associated to the conventional methods, having the advantage of being a low cost method and of proven efficiency in the treatment of ulcers and other diseases.
