Food Grade Borax?
I'd love to try these two remedy components but in the United States Potassium Bicarbonate is only through prescription and Borax is a toxic laundry soap. Do you have any suggestions on what I should use instead?
Borax is quite safe if the amount is used small enough and diluted greatly in a water, such as 1/8 teaspoon diluted in one full liter of water. It is quite possible to reduce that further such as using the same amount in even 5 liters of water, which amounts to 1/(8 x 5) = 1/40 of a teaspoon, assuming an average person drinks 5 liters of water in a day.
Much of the toxicity therefore is due to the concentration of the materials, more than anything else. If a single salt is dissolved in a large swimming pool of water, such saltiness can't even be detected. I can't even detect salty water (assuming the water is not contaminated) if 1/4 teaspoon of sea salt was added to one liter of water).
As to the potassium problem there are ways to get around that by drinking some electrolyte drinks or Rehydration Salts, which do have some potassium. Potassium is not needed in as much if we compare that against the sodium. Most cells tend to bathed more in extracellular fluids where sodium usually predominates over potassium. Also most fruits are also high in potassium just the same.
