I've been reading on the second page of these posts that one poster said he felt Borax supplies 75 mg in a 1/8 tsp--but Dr. Newnham said "...40-60 grams was a dangerous dose and children had been killed with much smaller doses...... So I took 30 mg of borax twice daily, this was 6 mg of elemental boron a day and in a week the pain was less, in ten days the pain was less. In three weeks the pain, swelling and stiffness had all gone, so I stopped taking the borax. A year later the pain and swelling returned so I took more borax and in two weeks all was right again."

It seems that if 75 mg is 1/8 of a tsp, but Dr N. took 60, forgive my math (it's horrible) but wouldn't that mean you should be taking less than 1/8 to get 60 mg (his 30 mg 2x a day)??? So why is everyone taking so much more than he researched and recommended? Pls explain. I am all ears and I don't want to take too much or risk poisoning myself!! Tnx

Please! Do yourself a favour, and STOP TAKING ANY AND ALL SUBSTANCES until you buy a scale....

When weighing doses of any particular substance but ABSOLUTELY WITH NO EXCEPTIONS for drugs/medication, you NEED to be using a Calibrated Milligram Scale (so the units appear as 0.000g and in this case if you want 75mg you want it to read 0.075g when weighing out your dose.)

1/8th of a teaspoon is NOT a unit of measurement, maybe for flour or something that doesn't matter at all, but NOT for medications when the recommended doses are in the milligrams... JUST so we are clear, a milligram is 1000th of a gram, this is miniscule in comparison.. If you were to use this spoon method with a more harmful substance you would SURELY kill yourself! PLEASE be careful!

I write this for your benefit and ONLY with pure love, nothing else! ❤️

Borax is less toxic than table salt. In the case of Borax, I think the measuring spoon dosage is perfectly fine. A scale would be useful for perhaps things like Sodium thiosulfate.

Borax is not elemental Boron. So your example is a bit flawed. Now if they are purchasing pure powdered Boron reagent grade or higher than yes you are 100% correct.

The doses involved on this site do not require the precision that you are demanding. The mineral Sodium Boron is less toxic than Sodium Chloride and it's LD50 is much higher. No one would be alarmed at someone putting a 1/4 teaspoon of table salt aka Sodium Chloride in a liter of water and drinking it let alone using an accurate scale to measure out the amount wanted.

In fact in nature water supplies can have up to 300mg/L and soil 33mg per kilogram.

The LD50 for Borax is 3.16gm/kilogram so 3160mg per kg of mass. So a 150lbs. man or 68kg man would need to consume 214,880mg of Borax in a day to have a 50% chance of death. Now if talking about elemental Boron, not Borax, I think adults have died at 15,000mg to 20,000mg. So again a huge safety profile for the dose being recomended on this site and other sites.

You would really have to work hard to get to those levels. Most people get lose stool the first time they ingest 1/4 of a teaspoon in water I can not imagine anyone ever approaching a level that would be of true concern. Again it is less toxic than table salt!

A dose in mg/kg for a rat is not the same as a dose in mg/kg for a human. You need to adjust the body area/size between species. See: https://pmc.ncbi.nlm.nih.gov/articles/PMC4804402/
