A system of holistic acu-light therapy developed by Peter Mandel, colorpuncture applies different frequencies of visible light onto the meridians where needles are typically placed during acupuncture. By using differing colors, energy can be manipulated, either to stimulate or sedate. Gentle, relaxing, and noninvasive, colorpuncture is sometimes used as an alternative to acupuncture for children and adults uncomfortable with the use of needles.
