I believe it is the combination of borax and Iodine that gives the good results. I have tried only Iodine in some cases, but this have not given the result they wanted.
Like a female friend of mine; frequent urination was the problem. When out drinking beer or coffee, she had to see the lavatory at least 4 times more frequent than me.
She have had this problem for years.
She tried Iodine with all companions as I suspected a hypo T in her. It worked pretty well, but had no effect on the frequent urination until I put her on borax too (after approx 3 months on iodine). In just a week the visits to the wc was reduced 2/3, and have stayed that way.
This is where borax have worked the best, fast; frequent urination and bedwetting in children.
Have no idea why it works tho :)
"Borax may be some type of secret internal cleanser that will someday become more popular."
-yes, you may be into something.
