I find bicarbonate of soda good. I use that in place of toothpaste when I'm taking anything homeopathic (when peppermint, in most toothpastes, should't be used).
bicarbonate of soda is very alkalinising too I believe.
I will put more thought into this and make sure I post anything else I can come up with.
We need to stay active in advancing possible treatments for this insidious menace of a thing!!
