A detoxification method includes immersing at least a portion of a patient's body within a reservoir filled with water; generating ions within the water; and simultaneously with the generating ions, irradiating a predetermined area of the therapy subject with light generated by a cold laser. The generated light may be irradiated to the patient as either a continuous beam or a pulsed beam. The ions generated within the water may be positive, negative, or combinations thereof. Further, the light may be irradiated as long as the ions are being generated.
