I have to agree. I tried naet and a technique similar to naet. I got no results. Perhaps my case was too complicated and I didn't give it long enough. But, it wasn't cheap, and I never would have continued for 100 treatmensts. I have to say my therapist was very kind and caring and tried hard to help me.
It may work well for a simple, clear cut allergy, but not in my case.
I got much better results with Donna Eden's energy medicine and EFT and diet changes. And yes, the immune system is key.
