@drandolph1951 Psyllium husk is an excellent source of fiber for treating both diarrhea and constipation. It absorbs water in your digestive tract to form a gel. So if you’re suffering from diarrhea, it traps excess fluid, firms up loose stool and slows down digestion. For constipation, Which I’ve only had once over 40 years ago when I was pregnant, it softens and bulks hard stools.
