Ginger may help ease functional dyspepsia, according to a small study from the World Journal of Gastroenterology. A condition marked by abdominal pain, functional dyspepsia often causes an uncomfortable feeling of fullness after eating (similar to the symptoms of indigestion). For the study, 11 people with functional dyspepsia took either ginger supplements or a placebo prior to eating a meal. Among those given ginger, researchers noted speedier gastric emptying (the time it takes for food to leave the stomach and enter the small intestine). However, ginger did not appear to improve gastrointestinal symptoms. Ginger may help treat other stomach troubles. For instance, research shows that the anti-inflammatory herb can help alleviate nausea caused by morning sickness. There's also some evidence that ginger may relieve stomach upset experienced by people undergoing chemotherapy.
