Reflexology, or zone therapy, is the practice of massaging, squeezing, or pushing on parts of the feet, or sometimes the hands and ears, with the goal of encouraging a beneficial effect on other parts of the body, or to improve general health. There is no consensus on how reflexology does or could work in practice; a unifying theme is the idea that areas on the foot correspond to areas of the body, and that by manipulating these one can improve health through one's qi. Concerns have been raised by medical professionals that treating potentially serious illnesses with reflexology, which has no proven efficacy, could delay the seeking of help from proven conventional medicine. However, registered reflexologists operate according to a code of conduct and would not diagnose a serious medical condition or treat one without medical consent.
