Effective Natural Remedies for Managing Diarrhea

My mom, 82, has bouts of diarrhea every month or so. This last for hours and hours and then slowly it subsides and next day she is okay. I remembered reading about taking ACV for this. I asked her if she would try it and she said yes. I mixed 2 tbsp of ACV (with the mother), and 1/4 tsp of baking soda (without aluminum from health food store) and about 8oz of water, and she drank it. She said immediately that she felt better. I checked on her about 15 minutes later and she said she was 100% better! I'm just elated! And so is she of course. Thank you EARTHCLINIC and TED! And thanks to all who posted their experiences about ACV and diarrhea.
