Vibrational medicine, also known as energy medicine, is a branch of alternative medicine that posits that all matter, including the human body, is composed of energy that vibrates at different frequencies. Practitioners of vibrational medicine believe that disease and illness are the result of disruptions or imbalances in these vibrational frequencies, and that restoring balance can promote healing. This approach incorporates various therapies, such as sound healing, color therapy, and the use of crystals, to influence the body's energy fields. The term "vibrational medicine" is derived from the idea that everything in the universe, including thoughts, emotions, and physical matter, vibrates at specific frequencies. In Hebrew, vibrational medicine can be translated as רפואה תדרית (refua tedrit). In German, it is known as Schwingungsmedizin, and in Spanish, it is referred to as medicina vibracional. While vibrational medicine is not widely accepted by conventional medical practitioners due to a lack of empirical evidence, it remains popular in holistic and alternative health circles. Key figures in the field include Dr. Richard Gerber, author of "Vibrational Medicine," and Dr. Mitchell Gaynor, who has explored the use of sound and vibration in cancer treatment.
