Each of the AMI devices, invented by Dr. Mandara Cromwell, provide frequencies that restore balance to the body with quick and easy-to-use thirty-minute channels. The design of the devices and Acoustic Meridian Intelligence concept are based on the idea that specific frequencies can travel the meridian pathways of the body. The AMI devices use ancient techniques, combined with advanced sound technology, applying sound trans-dermally to the body through the feet or hands.
