Are there any natural supplements that aid in healing a stomach ulcer?

Natural un-sweetened licorice is recommended by Healthline to reduce the symptoms associated with stomach ulcers. Foods rich in flavonoids, which include berries, broccoli, legumes and kale, can help ulcers heal. Some flavonoid-rich foods must be avoided, however, as they are acidic and add to ulcer symptoms.

Acidic flavonoid-rich foods include red wine and citrus fruits, and these foods should be avoided when treating stomach ulcers, adds Healthline. Coffee, high-sugar foods and carbonated beverages must also be avoided when treating ulcers. Milk must especially be avoided, as it contains calcium, which stimulates the production of stomach acid. A diet rich in fruit, vegetables and whole grains aids in fighting stomach ulcers, as it provides ample amounts of vitamins.
