The term alchemy goes back thousands of years. It refers to transmutation or change. Most people are familiar with the alchemical reference of turning lead into gold. That was the goal of the alchemist: to create or facilitate positive transformations. Overtime the term became associated with healing because people would go to an alchemist to get herbs or potions. Carl Jung applied the term to psychoanalytic methods where part of the process was working with archetypes and inner guides. In hypnosis, in very general terms it has come to represent work where the client brings in guides to give them advice or council in hopes that the client can bring positive transformations to their life.
