Support for psychological therapies which have the aim of bringing about remission of diseases by changing patients’ subconscious belief system is still very low in Japan, and this also applies to the therapies of energy healing and spiritual healing. We gave an overview of ThetaHealing® which combines such therapies at the last ISLIS symposium. EEG (electroencephalography), psychological (POMS), and immunological data of subjects during ThetaHealing® sessions were included in that interim report. This time, we would like to show more data which supports the safety in considering the introduction of ThetaHealing® into integrative medicine.
