It’s been used long time to improve treatment of kidney disease.
Turned my Dad’s completely around and he was in kidney failure.
My best friend’s mother did the same thing...although she also added a drop or two of apple cider vinegar to the baking soda/water mix.
She was near renal failure because of diabetes when she started taking the remedy at the advice of an elderly neighbor lady. About 6 weeks later...she was 100 percent better.
That was 8 years ago.
I take the same remedy for acid reflux...and its gone...along with the zantac.
