If you have occasional heartburn, acidity home remedies are the best thing to try out. Some of the things that could be of immediate use and relief to you are common household items that you have in your refrigerator or in your pantry. For example, mustard is proven to help with acidity so the moment you feel the problem coming on, eat one or two spoonfuls of mustard and you should feel some relief within five to ten minutes. Another thing that can help with your acidity is baking soda. A mixture of baking soda and water is very effective in lessening the acidity in the stomach. However this old standby should be used only once. Dissolve ¼ teaspoon of baking soda in ¼ cup of water and drink it as soon as you feel the acidity. A lot of people are using warm water for this as it has an extra mild effect.
