I tried out the internal borax today. Later on I had moderate/severe symptoms of toxicity such as kidney pain, confusion, tremors, chills, weakness, heart racing etc! I began to taste the acid/metal taste of borax in my mouth even though I hadn't drunk it for hours. It was as if my body was using every means possible for expelling the stuff from my system. I couldn't keep my train of thought and I would keep forgetting what I should do next or what I had just thought of a few moments ago. I was scared I was going to die I felt so horrible. I was afraid to sleep in case I died in my sleep.
I guess since I have weak kidneys (always had from a kid) as well as using the borox every night for three nights topically, I guess my body's levels just rose too high for me to fight it off. I was completely ready to go to the emergency room... except the person I was talking to at the poison control center had no idea what boron toxicity was. Miraculously my constipation eased up considerably (almost the opposite in fact) and I felt like some of the effects were eased enough so because of that I can deal with the rest of it. My kidneys are still in a moderate state of pain and I have some light-headedness still. Just potentially warning those people who may decide they want to go this route, especially if their kidneys aren't in top-notch shape.
Reading up on this states that boron is toxic in levels as low as 3 grams for a 60-kilogram woman. I don't know how much I had. A pinch and a tiny smudge more dissolved in 500 ml of water. But couple that with the amount absorbed through my skin and it might have been a lot more than what I thought.
Just warning those who are contemplating trying it. It very much didn't work for me. Wish I didn't attempt it.
