Psyllium seed husks

From Wikipedia, the free encyclopedia

Psyllium seed husks, also known as ispaghula or simply as psyllium, are portions of the seeds of the plant Plantago psyllium or Plantago ovata.

[edit] Description

Psyllium seed husks expand and become mucilaginous when wet and are soluble in water, but they are indigestible in human beings. The husks are dried and chopped or powdered for use. They may form one ingredient of several in finished products, or they may be used as-is, uncombined with any other ingredients.

Psyllium seeds are very similar to the seed husks and can be used for many of the same purposes, although their use is less common.

[edit] Uses

The characteristics of psyllium seed husks make them useful for any treatment that requires improvement or maintenance of transit time in the gastrointestinal tract, since the inert bulk of the husks helps provide a constant volume of solid material irrespective of other aspects of the diet or any disease condition of the gut. Over-the-counter laxatives and fiber supplements such as Metamucil, Serutan, Effersyllium, and Isabgol have psyllium husks as their main ingredient, in finely chopped or powdered form. The husks can be consumed as-is (with plenty of water or other fluid) with much the same effect. Psyllium can also be added to food or drink to boost the fiber content of the diet, and some cereals (Bran Buds, Heartwise) contain it.

Psyllium husks are used to relieve constipation, irritable bowel syndrome, diverticular disease, and diarrhea. They are used as a regular dietary supplement to improve and maintain regular GI transit. Some recent research is also showing them to be promising in lowering cholesterol and controlling diabetes.^{[citation needed]}
