Quantum Biofeedback scans the client's body looking for  viruses, deficiencies, weaknesses, allergies, abnormalities and food sensitivities. It reports on the biological reactivity and resonance in the body and indicates needs, dysfunctions and vulnerabilities. This information tells about the energetic state of one's body and the direction in which the body is focusing its energy. These figures are then compared against a "norm".   Reactions to various types of foods, chemicals, and other substances are revealed and can be further investigated to locate patterns and more clues.  Quantum Biofeedback also feeds back its own frequencies to neutralize destructive wave patterns. In some cases it may add frequency, in others reverse it to either enhance or counteract the body's own resonances.
