Several natural remedies, including chewing gum, eating licorice and drinking aloe juice, may relieve acid reflux symptoms, according to Fox News. Drinking a glass of water mixed with 1/2 teaspoon of baking soda or 2 tablespoons of slippery elm may also help reduce acid and protect the stomach.
As of 2015, limited research has been performed on herbal remedies for acid reflux, notes WebMD. One supplement, called Iberogast, may decrease digestive symptoms, such as heartburn, nausea and stomach cramps. Iberogast contains caraway, angelica, lemon balm, milk thistle and peppermint, along with Clown's mustard plant, German chamomile, greater celandine and licorice. Research has not determined which of these nine herbs relieves acid reflux symptoms.
