YOU WRITE - (I bought NaClO2 ultra poor from a chemical company - it get
yellowish after mixing with citric acid )." Is what you are giving your father exactly like the mms that Jim Humble suppliers have? Are you making your own mms? Because you said you got it from a chemical company? Why didnt you just buy it from a mms supplier? In my opinion that is the safest route right now.
I worry that if the sodium chlorite is not diluted properly maybe problems would result? Jim Humble's Miracle-Mineral-Supplement sodium chlorite solution has specific measurments for good reasons. So, just curious what you have there?
