Just a second...
The wiki text is clear that Borax is nearly all Boric Acid, he should have known that..
The text also says that AFTER reacting we get ~11% boron. Now in my posts I have pointed out that this is not a very good form of Boron. This is however not as important as understanding that Borax is Boric Acid so it tends to react faster with ionizing radiation then anything else.
Pure BOric Acid is used to stop the reaction of nuclear rods to make it possible to transport the stuff safely.
>>therefore one teaspoonful is approx 140mg or boron
Huh? Typo, brain scramble?
>>I tried 150mg of boron
Huh? Save dosage is 20 mg per day, whats up?
The key [for fluoride] is to get the Boron in the correct location in Boron form. This as I have typed over and over and over and over and over and over again can only be done when it includes BOron in Asparatate form:
Doses up to 18 mg of boron daily appear to be safe for adults even if taken for prolonged periods of time. This is double the dose of even the most liberal amounts suggested by advocates of boron use. There is also no evidence to suggest that boron is either carcinogenic or mutagenic.
In 1904, human volunteers consuming greater than 500 mg of boric acid daily (this is equivalent to about 180 mg of elemental boron) showed symptoms of poor appetite and digestive problems. Symptoms of acute toxicity typically include nausea, diarrhea and abdominal cramps.
