Also known as sodium bicarbonate, baking soda has a variety of uses, from treating an upset stomach to soothing heartburn. Drinking dissolved baking soda in water neutralizes acidity in the stomach, caused by a number of different foods and beverages, such as tomatoes, chocolate, citrus, alcohol and carbonated drinks. Lifestyle choices, such as smoking or taking aspirin, can also cause increase stomach acidity.
Pour a minimum of 1/2 cup room temperature water into a drinking glass. Set the glass aside.
Measure 1/2 tsp. of baking soda. Add the baking soda into the glass of water.
Stir the water and baking soda mixture with a spoon until the granules are completely dissolved. Baking soda is soluble in water at .274 oz. of baking soda to 3.5 oz. of water at 64 degrees Fahrenheit.
Drink the solution to help with stomach acidity. Repeat the process every two hours, without exceeding 3-1/2 tsp. in a 24-hour period because of the high levels of sodium contained in baking soda.
