Make sure that you have a good intake of potyassium, as barium can interfere with potassium metabolism and affect heart function. EDTA seems to be the best chelator of barium. Barium also combines with oxygen, hydrogen, carbonate, sulfate, and halogens like chlorine and fluorine. When taking EDTA, it can be helpful to take trace minerals, calcium carbonate, potassium and sodium bicarbonate, and vitamin C.
I would consider the McCombs Plan for reversing the fungal candida back to its normal yeast form. The typical die-off reaction is eliminated or minimized through the sweating on the Plan. Keep the bowels moving also. Normal bowel movements are 3-4 times a day.
A great reference for barium is found here -
