Patient Education

Psyllium


Psyllium, a bulk-forming laxative, is used to treat constipation. It absorbs liquid in the intestines, swells, and forms a bulky stool, which is easy to pass. This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

Black Psyllium


What is it? Black psyllium is a plant. People use the seed to make medicine. Be careful not to confuse black psyllium with other forms of psyllium including blond psyllium.

Black psyllium is found in some over-the-counter medicines and is effective for treating and preventing constipation. It is also used for diarrhea, obesity, diabetes, and for reducing the risk of heart disease, but there is less evidence that it is effective for these conditions.
