I'm vaguely familiar with hypnotherapy and NLP (neuro-linguistic programming). Are there any papers published in prestigious journals on this subject? Or is this crackpot stuff. I've heard that a potential cause of allergy may be anchoring allergic reaction to pollen when experiencing trauma. That way, a person's allergic reaction will be triggered when being exposed to pollen. Furthermore hypnotherapy claims, since allergy is all in your head it may be cured with NLP. Is this for real?
