For more than 20 years, Dr. McMakin has taught basic and advanced FSM courses to professionals all over the world and continues to amass a database of useful frequencies and successful case study reports. It is through this empirical method that the knowledge base of FSM has expanded. Currently, there are protocols for all body systems as well as protocols for anxiety and depression. It is not a cure all. It works if the diagnosis is correct and if the proper frequencies are selected. For me, it is another tool along with homeopathy, osteopathy and conventional medicine that I use to promote healing from within.
