Potassium salt is often used as a substitute for regular sodium chloride salt (the salt you find on your kitchen table), and for good reason. Most people in the United States take in too much salt on a daily basis, which may put them at risk for hypertension, heart attacks and strokes.
Major uses of potassium nitrate are in fertilizers, tree stump removal, rocket propellants and fireworks. It is one of the major constituents of gunpowder (blackpowder) and has been used since the Middle Ages as a food preservative.
