I confess that although I've had the technique applied by various holistic health practitioners, I don't have a whole lot of knowledge on the subject.
I've been told that it only measures the benefit of whatever you are testing for (a remedy, nutrient, relationship, whatever!) IN THAT GIVEN MOMENT! They tell me if you test again an hour later, you might get a very different answer. That being the case, how is this method beneficial??
Please, any and all who have understanding of how this modality works, feel free to enlighten me! I just don't know enough about it. I will dowse for answers to similar questions as others use muscle testing for, but I recognize there is room for error in THAT method also!
