Several years ago I had persistent stomach pains with no known cause or prior illness which I suspected was e. coli. I did not see a doctor as from past experiences I tried to keep my dr. visits way down and just use natural remedies when possible. Here is an inexpensive e. coli treatment you can try that I fortunately found in an article by a cranberry juice company and was very effective in relieving my symptoms: On an empty stomach drink 8 oz of pure (no additives) cranberry juice followed immediately by 2 tablespoons of pink bismuth. Do this 3 times a day for 1 week. In theory, the cranberry juice dislodges the e. coli from the stomach and the pink bismuth carries it out to the bladder for expulsion.
EC: Pink Bismuth = Pepto-Bismol or Kaopectate
