Ispaghula husk is a soluble fibre that comes from a shrub-like herb, Plantago psyllium. Ispaghula husk is also known as psyllium, psyllium seed, psyllium husk, ispaghula or ispaghula seed.
Ispaghula husk is a central ingredient in many high-fibre cereals, and is often combined with wheat and oats. It is also contained in many processed foods such as "health drinks", bread, biscuits, rice cakes, instant noodles and other bakery products and is also sold as a supplement such as Metamucil, Colon Cleanse, Serutan, Fybogel, Bonvit, Effersyllium, and Konsyl.
This study investigated the effect of ispaghula husk supplementation on recurrence of colorectal adenomas in patients with a history of colorectal adenomas. (An adenoma is a benign tumor of glandular origin. Although these growths are benign, over time they may progress to become malignant). The study included 665 patients who received either supplementation or placebo and were followed for three years.
The study found that patients who had the ispaghula husk had a 67% increased risk of recurrence of colorectal adenomas compared to patients who had placebo.
