Interventions/Control_1
The subjects take 2 kinds of supplementary diets for 2 weeks each, with a 1-week washout period between them. The placebo supplementary diet(control) is freeze-dried miso soup and the experimental diet is freeze-dried miso soup supplemented with 10 g of burdock powder. The supplementary diets are taken twice daily, at breakfast and dinner, with their usual diet for 2 weeks. Thus, the daily administration of burdock powder during the administration period is 20 g. The order of the supplementary diets for each subject is randomly chosen.

Results
Seven patients were analyzed. There were no significant differences regarding mean bowel frequency and stool consistency between the burdock powder administration and control periods, though burdock powder showed a tendency to increase bowel frequency and make stools softer. The numbers of radiopaque markers remaining in the colon at the end of the control and burdock powder periods were not different. No adverse event related to consumption of roasted burdock powder was observed.
