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.

Blond Psyllium


What is it? Blond psyllium (Plantago ovata) is an herb. Its seed husk is used as a laxative and stool softener and to help reduce cholesterol.

Psyllium seed husks absorb water in the stomach and form a large mass. This mass stimulates the bowel in people with constipation. In people with diarrhea, it can slow down the bowel and reduce bowel movements. This mass can also reduce the amount of cholesterol that is absorbed into the body.

Blond psyllium is commonly used as a stool softener in people with constipation and hemorrhoids. It is also used for diarrhea, irritable bowel syndrome (IBS), high cholesterol, heart disease, and diabetes. It's used for many other conditions, but there is no good scientific evidence to support most of these other uses.
