Part(s) Used: Seed and husk
Constituents/Active Ingredients: 10-30% mucilage, mainly concentrated in the husk or outer epidermis of the seed coat. This soluble fibre is largely made up of xylose, galacturonic acid, arabinose, and rhamnose. The seeds also contain: hemicellulose; 15-20% protein; 5-13% fixed oil with linoleic and oleic acid esters (omega-6 and 9 fatty acids); phytosterols; triterpenes; aucubin (iridoid glycoside); and the alkaloids plantagonine, indicaine, and indicamine.
Overview: Psyllium products, also known as ispaghula, consist of the dried, ripe seeds of the plant, as well as preparations of the ground/powdered seed and husks. Psyllium has a long history of traditional use as a medicine in the US, Europe, India, and China. Psyllium seed was traditionally used for treating chronic or occasional constipation, as a soothing, non-irritating bulk laxative, as an absorbent fibre for treating diarrhea and for alleviating irritable bowel syndrome, gastritis, and diverticulitis. Some other uses of psyllium in traditional medicine include as an emollient, demulcent, and diuretic.
