Reflexology:

Also known as "zone therapy", this philosophy is based on the idea that specific points on the feet and hands correspond with organs and tissues throughout the body. With fingers and thumbs, the practitioner applies pressure to these points to treat a wide range of stress-related illnesses and ailments.  Reflexology as a therapy (foot massage) has been found to lower the anxiety of pregnant women ( Altern Complement Med. 2018 Feb 23.) and decreased pain and anxiety after abdominal hysterectomy (Complement Ther Med. 2018 Feb;36:107-112.)  There is little evidence reflexology has any benefit to distant organ health or as a diagnostic tool.
