This therapy utilizes the effects of different wavelengths of light on the human body. Scientific research has confirmed what the ancients knew long ago - that different colors have very definite properties and affect the body in very different ways. Some colors can stimulate a sluggish organ into greater activity, while others can soothe hyperactivity and calm a stressed nervous system. This treatment is particularly useful in combination with acupuncture to deepen the relaxation of the nervous system during treatment.
