AAT treats the symptoms associated with allergies and sensitivities by reducing the biological stress caused by the offending substance. Gentle pressure is used to stimulate points on the back, which correspond with the major organ systems. According to traditional acupuncture theory, this stimulation relaxes the body and temporarily strengthens each of the major organ systems. During treatment, a digital representation of the substance is introduced to the surface of the skin. Acupressure stimulation is then applied to reduce the stress load caused by the substance. The body associates the enhanced state with the substance, allowing for a more appropriate response.

The degree of stress on the organ systems, caused by an allergen, is proportional to the degree of the negative reaction. By easing the stress on the organ system involved, the related symptoms are also reduced, allowing for a positive conditioning effect.
