2. Baking Soda
Acid reflux is at least partly caused by acid (the clue is in the name). This is because the sphincter in the esophagus becomes loose and opens up (this is called the esophageal sphincter). That in turn allows food and acid to make its way back up the food-pipe, instead of this being a one-way system. This causes indigestion when the acid makes its way to the chest and it causes reflux when the food makes its way into the mouth.
The acid is the most dangerous and serious issue here as it damages the lining of the esophagus, damages the teeth and smells. To neutralize this then, you can use any alkaline substance – and one of the most common choices is to use sodium bicarbonate. Mix with a little water and the pH level will help to provide some instant relief as well as minimizing any damage that might have been caused by it. Baking soda can also be a great choice for generally settling the stomach and is something you should keep around the house in general.
