Two medical review articles conclude that "NAET has to be the most unsubstantiated allergy treatment proposed to date" and that "there have been no studies supporting the use of these techniques". The Teuber and Porch-Curren review cautions that "there is the potential for an anaphylactic reaction if a patient with severe food allergies seeks such a therapy and tests themselves by oral challenge away from a physician's office after completing the NAET sessions successfully". The Australasian Society of Clinical Immunology and Allergy has advised against using NAET to treat allergies, criticizing its "lack of scientific rationale" and describing it as a "potentially dangerous technique".
