Patient Education

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.

Senna


What is it? Senna is an herb. The leaves and the fruit of the plant are used to make medicine.

Senna is an FDA-approved over-the-counter (OTC) laxative. A prescription is not required to purchase senna. It is used to treat constipation and also to clear the bowel before diagnostic tests such as colonoscopy.

Senna is also used for irritable bowel syndrome (IBS), anal or rectal surgery, tears in the lining of the anus (anal fissures), hemorrhoids, and weight loss.

Senna fruit seems to be gentler than senna leaf. This has led the American Herbal Products Association (AHPA) to warn against long-term use of senna leaf, but not senna fruit. The AHPA recommends that senna leaf products be labeled, "Do not use this product if you have abdominal pain or diarrhea. Consult a healthcare provider prior to use if you are pregnant or nursing. Discontinue use in the event of diarrhea or watery stools. Do not exceed recommended dose. Not for long-term use."
