Richard Gerber, MD, is the author of the best-selling "Vibrational Medicine," which launched a revolution in health care. Gerber's follow-up, "Vibrational Medicine for the 21st Century: The Complete Guide to Energy Healing and Spiritual Transformation," synthesizes the best of non-Western ancient healing wisdom with the latest discoveries in science to produce an entirely new approach to treating and diagnosing illness, based on the belief that the human body is a complex system of pulsing energies that need tuning and balancing.
