Reflexology is an alternative medicine technique that involves applying pressure to certain points on the feet, hands and ears that are believed to correspond to different parts of the body. The document discusses how reflexology is based on the principle that stimulating zones in the feet, hands or ears can positively impact related areas of the body like glands, organs and systems by correcting imbalances. A brief history of reflexology is provided, noting its origins in ancient Egypt and its modern founder William Fitzgerald. Potential benefits include relaxation, improved circulation and stress reduction, though adverse reactions like fatigue or nausea are possible.
