Iberogast, a mix of nine different herbs, has helped heartburn in some studies, and calcium supplements and chewing gum also reduce stomach acid. Other home remedies, such as drinking milk, end up spurring the stomach to produce even more acid, as stated by WebMD.
The acid-fighting properties of calcium have been common knowledge for some time, as it is also the active ingredient in a lot of the antacids that are available over-the-counter. However, milk is not a suggested solution for stomach acid, as other ingredients cause the stomach to make more acid. If calcium supplements or antacids do not work after a couple of weeks, an individual should consider being tested for gastroesophageal reflux disease, notes WebMD.
Chewing gum spurs the body to produce saliva, which buffers acid in the stomach. Chewing gum also causes people to swallow more frequently, which kicks acid from the esophagus back down into the stomach. Sugar-free gum fights heartburn and tooth decay at the same time, states WebMD.
Other natural treatments for heartburn include staying away from foods that cause heartburn, such as peppermint, chocolate, citrus juice or fruit, onions, tomatoes and fatty foods. Adding fiber to one's diet keeps the digestive system moving, allowing acid less time to settle. Eating no fewer than 2 or 3 hours before bedtime allows the stomach to empty before one lies down. Even losing weight helps, as extra fat in the abdomen presses on the stomach, pushing acids back to the esophagus, according to WebMD.
