Ginger: Since ancient times, people have turned to ginger as a cure-all for pain to nausea and everything in between. It's not just an old wives' tale, either — studies have shown that ginger can be a very effective treatment for some kinds of stomach upset.
A natural anti-inflammatory, ginger is available in dozens of forms, all of which can help. Ginger chews and supplements are easy to take, while other people prefer their ginger in beverage form. Try an all-natural ginger ale or chop up some fresh ginger root and make a tea.
Apple Cider Vinegar Soothes an Upset Stomach: A mixture of one tablespoon apple cider vinegar, one cup warm water, and one tablespoon honey will ease indigestion and may alleviate cramping and gas in your upset stomach. It can also lessen discomfort caused by heartburn.
Caraway Seeds Ease an Upset Stomach: Caraway seeds are packed with vitamins and minerals, which inhibit the growth of bad bacteria that causes indigestion, gas, or bloating and contributes to an upset stomach. Nibble on a handful after eating your meal, or if you feel gassy.
Yogurt Reduces Discomfort from an Upset Stomach: You probably don't crave anything dairy when you have a stomachache, but the probiotic qualities of yogurt—aka live bacteria—make it a good cure as it eases digestive discomfort and boosts your immune system. Just make sure to choose non-fat plain yogurt without added sugar or flavors when you have an upset stomach.
