NAET stands for Nambudripad's Allergy Elimination Techniques. Similar to the common allergy treatment of micro-dosing with certain allergens such as peanuts, NAET involves exposure to the substance while you rest with acupuncture needles in your body.
In order to determine what allergens are causing the majority of your symptoms, one might choose to go through allergy testing prior to receiving NAET treatments. In the event that allergy testing has not been done, or a patient is not interested in going through that process, muscle testing can be used in order to determine which substances are causing the reaction.
Once that has been determined, pressure is applied to the back, all along the spine, while the patient lays face down, with a vile of the substance in their hand. Then, the patient lays face up while a series of acupuncture needles are inserted. After resting with the needles in for 20 minutes or so the treatment is complete.
Depending on the severity of the allergy symptoms, patients require a varied number of treatments in order to experience a full recovery. By the end of the series of treatments, the patient is able to consume or otherwise be near the substance without symptoms.
