No. I don't have that, either. But ten years ago, my Wife had Osteoarthritis bad enough to need three prescription-strength Motrins a day. Something needed to be done, so I did the research. Turns out there was a Ph.D. in Agriculture in Australia, Dr. Newnham, that started to develop it in the 1960's. As a teacher of Soil Science, he wondered if it was a soil issue. Started looking around to see which other countries had a bad rate of Arthritis. Turned out finding which ones DID NOT. Israel only has a 1% rate. He found that it was because the Borax from the Turkish Mountains goes into the water. So he started taking a "pinch" of Borax, however that much was, and his pain started to go away in three weeks. Long story shorter, he tried to market a Borax solution. Big mistake. He was fined a thousand dollars, and the Australian government and Australian medical community saw to it that you could not purchase Borax at all in the entire continent, or England, etc. Until just recently.
Toxicity? Less than common table salt. But in the 1920's a Boric Acid solution was mistaken for plain water, and some infants were killed. A woman in Child-bearing years should not take over 30mg of Boron (the mineral in it) per day.
Also, since I'm posting this to a woman, another story to tell. A while back, a thousand Turkish women of low socioeconomic status were selected for a study. About 500 from a low Boron area, 500 from high Boron. In the low boron area (such as what we get) they found 15 with Cervical Cancer. In the high Boron area, they found Zero. None at all. Prospect of that happening by random chance is greater than one in ten thousand. If you do a Cancer by Country search, you can find that Australia is #1, the U.S. is #5, and Israel is #50.
I'm 75, without a pain in my body, so maybe I'm doing something right. But I take the Boron Water, as well as my Wife, who has NO ARTHRITIS PAIN. Did I say that loud enough? It reduces the risk, on a dose-dependent basis, of at least Breast Cancer, Cervical Cancer, and Prostate cancer.
Cathy, I did a search and see that you are a writer. Nicely done. If you do the research to make sure I'm not making this up and decide to write about it, I applaud that. I see Arthritis as a mineral deficiency. As a start of research, I suggest the video https://www.youtube.com/watch?v=MmVzYnxrJi0 It will tell about things I haven't mentioned. If you need other information, such as calculating dose, just check back with me. This commentary has already gotten too long. And, obviously, I can't promise it will help your condition, but there's a reasonable prospect of it. One that has been hidden, and perhaps you can help correct that. If you do write about it, I'd appreciate a copy. I used to proof Galley Prints while I worked in the medical community.
