Borax helped my candida by killing most of it, and is one of the few things that can handle mycoplasma and toxins.
I use it internally (cosmetical grade) and mixed in my household cleaners, shampoo, soap etc.
Great if one lives in a humid climate; where mold and fungus trive. Mold, fungal based organism and insects have no utilization of boron, and are therefore killed by borax that contains 11 % boron. Humans and plants need and utilizes boron very well, and thrive on it (in right proportions of course)
