Took me a year:)
Combination of iodine, boron +++
It takes time, simple as that.
Been experimenting with borax - copper- Iodine solution lately for external use. But need to test it more on volunteers before I know if it is any good (or not)
After a long time break I started with cases again, I see pretty much the same in all of them; low body temperature, low function stomach acid, deficiency of many minerals, vitamins.
Plus most of them use far to much medications.
