Six elderly psychiatric and 17 mentally handicapped individuals suffering from severe constipation received 3 week periods of treatment with 10 g unrefined bran, three bran biscuits, and Senokot syrup daily or three times weekly. There was no significant difference in the number of bowel movements or enemas or in the consistency of the motions. The results suggest that bran may be substituted for laxatives.
