reflexology is to do with the feet being linked to everything and u can treat other parts of the body through them,
dunno how to explain better but google says:
Reflexology is a treatment which applies varying degrees of pressure to different parts of the body, commonly the hands and feet, in order to promote health and well-being. It is suggested that there are reflexes or zones running along the body and terminating in the hands or feet. All systems and organs are said to be reflected on to the hands or feet and by applying gentle pressure to specific areas of the hands or feet a change can be effected elsewhere in the body
