Here in danmark boron has become a controlled substance because of the environmental protective folk finding out it was killing off some of the native wetland life because of runoff from industrial uses and laundry detergents and the like.
I had to order my supply in from Turkey.
The apples here go soft and spongy very quickly once off the trees, and we had a lovely green apple tree in the garden that was cut down eventually due to a a fungal infection in the trunk.
That was before we took over the house (from family) and I had a supply of boron.
Supplemental boron is incredibly gentler on the body and brain. If you've got mycoplasmas at the achy root of your condition (for example autoimmune illnesses, HIV, diabetes (usually a complex with viruses involved too)), you'll want fat-based cleansers like coconut oil and the like. Colloidal Silver is turning out well for me too.
Mycoplasmas steal fats out from under your feet- which are -vital- for heathy cell walls and for mitochondrial health. You need to have plenty of fats available for the cell wall strengthening triggered by boron.
It's a subject worth looking into, since it's an infectious agent easily spread through vaccines.
TLDR: Use chelated boron supplements, borax will strip ye silly if you are dealing with a major chronic illness that results from fatty acid deficiency from tiny buggy parasites that live inside cells.
