Useful natural treatments for healing a stomach ulcer may include eating a healthy whole foods diet that is rich in flavonoids, and consuming deglycyrrhizinated licorice, zinc and mastic gum, according to WebMD and Healthline.
Nutritious whole foods may help an ulcer heal more quickly, explains Healthline. Research has demonstrated that flavonoids may be a beneficial treatment for stomach ulcers because they offer cell protective and antioxidant properties, according to the National Institutes of Health. Foods that are high in flavonoids include legumes, kale, broccoli, apples and berries. Natural deglycyrrhizinated licorice may also be helpful for soothing stomach inflammation, according to the Mayo Clinic. Zinc boosts immunity and speeds wound healing, and mastic gum may protect the lining of the stomach and reduce stomach acid levels.
