Baking soda is edible and is most commonly used as a leavening agent in baking. Baking soda can also be used, dissolved in water, as a drink to help ease stomach and digestive issues. Baking soda, or sodium bicarbonate, is an antacid and antiseptic and can boost the body's alkalinity.
Baking soda is high in sodium and should only be taken in small doses over a short period of time. It should not used at all by people with high blood pressure or those who are on sodium-restricted diets.
Using baking soda therapeutically has been shown to produce results for conditions such as arthritis, indigestion, heartburn and infection. It can also improve sport performance and is thought to help treat gout, kidney stones and urinary tract infections, according to MD Health.
