Packets of oral rehydration salts are widely available. To use one of these packets, mix the contents with 1 quart or litre of drinking water. If drinking water is not available, or if you are not sure the water is drinkable, boil the water for at least 10 minutes.

Sugar - Six level teaspoons (1 teaspoon = 5grams)
