Abdominal pain can signal an array of ailments. Sometimes the cause is as simple as too much food or alcohol. But occasionally, abdominal pain is a sign of a more serious problem, such as a disorder of the appendix, intestines, gallbladder, liver, kidneys, pancreas, spleen, stomach, or reproductive system. If the pain is severe or persistent, consult a doctor. With appendicitis, pain begins in the area of the abdomen around the navel and may move to the lower right or it may subside. The pain eventually worsens and is exacerbated by movement. See a doctor immediately. Homegrown cures for stomachache have changed little over the years. Mothers still send ailing children to bed with a heating pad or a glass of flat ginger ale. Another remedy called for a rag soaked in kerosene to be placed over the lower-right quadrant of the abdomen, in which the appendix lies; it was then covered with a towel and a hot-water bottle. Heat indeed helps relax cramps and improve blood flow. Undoubtedly less effective was the following advice: "To cure cramps, put a pan of water under your bed."

For every aching belly there was a tea or an infusion "guaranteed" to bring relief. Many were made from herbs that are still valued today, such as chamomile, peppermint, anise, cinnamon, sage, thyme, nutmeg, ginseng, and caraway seed. Most of these are carminatives, which help expel gas. Some, such as chamomile, are also thought to be anti-inflammatories, which help soothe an inflamed stomach.
