In 1971, Edgar Engelman, MD, conducted a study to find out if a spoonful of sugar really is an effective cure for hiccups. He assembled a group of 20 patients who had been experiencing intractable hiccups for more than six hours, eight of whom had had them anywhere from a full day to six weeks. Each of the test subjects was given one teaspoon of white granulated sugar to swallow dry, and for 19 of the 20 hiccup patients, the cure was immediate. André Dubois, MD, a gastroenterologist in Bethesda, Maryland, noted in The Doctors Book of Home Remedies that "the sugar is probably acting in the mouth to modify the nervous impulses that would otherwise tell the muscles in the diaphragm to contract spasmodically."
