The book of QT Universal Codes is designed as a self-help guide to assist a person in healing physical and emotional issues, as well as toxin sensitivities. These Universal Codes work well for many people for multiple issues. The term “Universal Code” is used in contrast to a “personal QT Code” given during a private session with a QT Practitioner. QT Universal Codes have been developed from working with thousands of clients. Patterns of recurring Codes were recorded during private sessions by QT’s founders, Dr. Stephen and Beth Daniel.
