The invention relates to a novel composition for relaxing bowels, and in particular relates to a dextrose candy added with fructo oligosaccharide. The composition contains fructo oligosaccharide as the main raw material and is prepared into the dextrose candy by adding a gastroenteric functional adjusting agent, an absorbing agent, a flavouring agent and the like through the processes, such as mixing, pelletizing, rounding, tabletting and screening. The composition disclosed by the invention is reasonable in formula; the side effects, such as intestinal tympanites frequently generated due to single use of fructo oligosaccharide, can be obviously lightened; furthermore, the bowel relaxing effect is prior to that of fructo oligosaccharide; blood sugar cannot be influenced; and therefore, the composition is particularly applied to young and old patients suffering from constipation.
