The Otto 128 is used for pain management, muscle spasms, or circulation. It promotes relaxation, enhanced memory, and enhanced sexual function by stimulating the nervous system and release of nitric oxide.The Otto 128 was shown by Dr. John Beaulieu to promote the release of nitric oxide, a gas in our blood vessels known to relieve pain and promote relaxation and health.The Otto (osteophonic) tuners are placed on joints, muscle and nerve groups which in turn resonate throughout the body providing relief from arthritis, knee or back pain, surgery or a strenuous workout.When used in conjunction with the Ohm-Earth Tuner, the Otto 128 will create an Ohm, the sound and frequency of the Earth.The Otto 128 tuner has been shown to stimulate the release of Nitric Oxide, an important and natural molecule for maintaining good health.
