Researchers have found that ferulic acid, a natural compound found in rice bran, may help reduce symptoms of diarrhea-related digestive disorders by calming overactive intestinal muscles. In laboratory experiments, ferulic acid reduced calcium signals that trigger gut muscle contractions, suppressing spasms caused by several chemical messengers. These findings suggest the compound could support future dietary or therapeutic approaches for conditions such as diarrhea-predominant irritable bowel syndrome. However, researchers caution that slowing intestinal movement could worsen constipation, so further studies are needed to confirm its safety and effectiveness in humans.
