Making your own Oral Rehydration Solution
How to make a cheap, safe, and effective ORS powder yourself.
The simplest formula is 3 Tablespoons of sugar, and 1 teaspoon of salt, dissolved in 1 liter of potable water. An alternative simple formula is 8 teaspoons of sugar, and 1 teaspoon of salt, dissolved in 1 liter of potable water. You may elect to add a flavoring to this mixture. Unsweetened Koolaid would add flavor and color, and make the drink more palatable to some.
This basic formula has been used effectively for more than 30 years by WHO, UNICEF, and other relief agencies and has saved millions of lives.
