It would be interesting to know the mechanism of the baking soda effect. I only use it as mouth wash (against acidity in my mouth), I wonder how it affects tumors.

Good job OP.

A strange thing that the supermarket where I used to buy pure baking soda run out of it a few weeks ago and they wont order it any more, they only have some crap baking mix instead of that, now I had to buy it somewhere else.
