What home remedies can help relieve pain from food poisoning?

Food poisoning can be caused by viruses, parasites or bacteria. The symptoms may include one or all of the following: nausea, vomiting, and/or diarrhea. The main goal of home treatment is adequate hydration. For watery diarrhea, over-the-counter loperamide or bismuth subsalicylate can help reduce the frequency of bathroom trips. If a person has fever, blood or mucous in the stool or cannot maintain hydration, medical evaluation is indicated.
