Iodine: this very vital substance has been villified by the same people who stand to gain the most from it's non-use: M.D.'s (truly a criminal racket)
So it's no surprise to see it's use disdained in an otherwise accurate review of the symptoms of so-called 'coeliac': grain-intolerance.
While I keep sources private and methods of preparation, it's use is quite simple: If you are outside of north america, it's easy to order it through the pharmacist, and they in turn order it from a lab, which in turn orders it through one of the big pharmaceutical companies. The price is very low compared to inflated prices I see online, either for liquid iodine solution or KI (potassium iodide, in tablet form).
How this applies to coeliac:
We know the internal organs, especially the small intestine, are attacked during coeliac symptoms.
Iodine is a totally necessary nutrient used in immune system and other organ building and function.
note: this excludes radioactive iodine, and 'surface treatments' which have been doctored (adulterated), such as betadine.
