As I suffer from nasal polyps, I was interested to read in WDDTY (vol 12 no 7) that avoidance of salicylates might help. However, I have been searching unsuccessfully to find what foods - as well as those you mentioned - I should avoid. I do not own a computer and so cannot search there. Therefore, please, is it possible for you to list them?

Your forthcoming book sounds fantastic and, after reading your excerpt, several points came to mind. Don’t practitioners of radionics heal through working on the energy field around us and, hence, into the physical body?
