Apple cider vinegar and food poisoning.
Use
Apple cider vinegar is used as a treatment after food poisoning has already struck. It cannot really prevent the illness from occurring, but it can ease the symptoms and speed your recovery once you are sick. According to "The Natural Remedy Book for Women," apple cider vinegar treatments can kill off the bacteria making you so sick. It can also hydrate you and replace some of the vital nutrients and minerals lost due to vomiting and diarrhea.
Remedy
The University of Maryland Medical Center recommends a fairly simple apple cider vinegar-based remedy for food poisoning. Pour 8 oz. of warm water into a cup, and stir in 2 tsp. of apple cider vinegar. Sip the mixture until it's gone, drinking it slowly to enhance your chances of keeping it down. Repeat the treatment three times daily until your illness has passed.
