Used for centuries in Indian and other Asian cuisines, ginger root also has a long history as a home remedy for digestive problems. A 2008 study published in the “European Journal Gastroenterology and Hepatology” found a scientific basis for ginger’s benefits to the G.I. tract, showing that it helps move food more quickly from the stomach into the small intestine for absorption. Steep a slice of peeled ginger root in a cup of hot water when you have an upset stomach. Ginger also appears to assist with inflammation, according to a report in “Arthritis Today.” Participants in a study at the University of Miami showed a 40 percent improvement in osteoarthritis pain after taking ginger extract.
