Baking soda, or nahcolite in its natural form, is part of the natural mineral natron, which is abundant in sodium bicarbonate and has been used since ancient times. Despite being of great help in the household, baking soda offers powerful medicinal properties.
According to Care2.com:
“Baking soda helps regulate pH—keeping a substance neither too acidic nor too alkaline. When baking soda comes in contact with either an acidic or an alkaline substance, its natural effect is to neutralize that pH. Beyond that, baking soda has the ability to retard further changes in the pH balance, known as buffering.
