Quick food poisoning help

One of my daughter's friends got food poisoning and I did a bit of research on natural help to get rid of it. The two easiest with ingredients we had on hand were: 1. Cut a lemon or lemons in wedges keeping the peel on. Steep in water like you would a tea bag and drink. 2. Squeeze four lemons into a cup and add enough sugar to taste. Drink (do not add water) and the ailment is said to be gone within 30 minutes! I haven't tried these but I will let you know if they worked for the dear girl trying them out! Note: Practice basic safety measures with this and educate yourself on causes, symptoms and treatments for food poisoning. http://www.webmd.com/food-recipes/food-poisoning/food-poisoning
