Diarrhea, abdominal discomfort, anorexia, vomiting or nausea caused by bacteria, viruses, parasites or toxins in contaminated food or water
Drink warm sweetened tea, or water mixed with a little honey and salt to prevent dehydration. Also bouillon with added salt, or strained broth. Avoid eating until symptoms have subsided, and then only bland foods like cooked cereals, jellied consomme, and live yogurt to replenish the friendly bacteria in the digestive tract.
To stop diarrhea, boil 1 tsp of oregano with 1 cup water, strain and drink 2-3 times daily. Also drink freshly made carrot juice with apple juice. An infusion with ginger is also helpful. If none of these is available drink a glass of Coca Cola.
