Origin and history
Psyllium is a herbaceous plant native to India and Iran, used for millennia in Ayurvedic medicine to regulate bowel movements. Its name comes from the Greek word psyllia , meaning "flea," referring to the small size of its brown seeds. Also known as ispaghula , psyllium is cultivated for its seeds and their husk (the seed coat) , which are very rich in mucilage—soluble fiber with exceptional properties for digestive comfort and intestinal well-being.
