The doctor behind it is a chiropractor who accidently stumbled upon her miracle cure. She claims a degree she doesn't have, which is also pretty shady.

Devi Nambudripad was a student chiropractor and acupuncturist at the time she developed NAET. Whilst experiencing a reaction to eating carrots she attempted to overcome the reaction through a self-administered acupuncture treatment. After the treatment the reaction to eating carrots did not return. At the time of the acupuncture treatment, a remnant of carrot was on her skin, and Nambudripad concluded from this that the presence of a minute quantity of carrot during the acupuncture treatment was the key to the treatment. She then formulated a hypothesis that contact with a small amount of an allergen during an acupuncture or acupressure session can remove reactions to food and other substances.[19]

NAET is promoted by her Nambudripad’s Allergy Research Foundation (NARF) which also publishes its own journal called The Journal of NAET, Energetics & Complementary Medicine.[20]

She is licensed as a chiropractor[1] and acupuncturist[2] in California. She also identifies herself as an M.D.. Her website states that she received the Doctor of Medicine degree from University of Health Sciences Antigua (UHSA) in January 2002.[21] The California Medical Board does not list an active license, and it does not recognize medical degrees from UHSA as valid, listing it as a "disapproved" school since 1995.[22]
