Background

Pomegranate is a small, fruit-bearing tree that comes from the Middle East and is now cultivated in many parts of the world, including the Mediterranean region, Southeast Asia, and the Southwestern United States.

Pomegranate was used in traditional medicine to treat intestinal parasitic infections, diarrhea, sore throat, and other conditions. It has been used orally (by mouth), topically (applied to the skin), and as a gargle or mouthwash.

Preparations from pomegranate are currently promoted for many conditions including high blood pressure, heart disease, and diabetes.

How Much Do We Know?

There’s some evidence from studies in people on the effects of pomegranate for a few health conditions. Many of the studies have used pomegranate juice rather than dietary supplements.

What Have We Learned?

Pomegranate juice or extract may be helpful in reducing blood pressure, but additional research is needed to confirm this effect.

Studies show that pomegranate may reduce blood glucose levels to a small extent.

Studies have been done to see whether various products from pomegranate can influence levels of cholesterol and other lipids, but no clear effects have been demonstrated.

The limited research that’s been completed so far doesn’t allow conclusions to be reached about whether pomegranate is helpful for any other health conditions.

What Do We Know About Safety?

Pomegranate juice is believed to be safe. Pomegranate extract may also be safe. Pomegranate root, stem, and peel may not be safe when consumed in large amounts because they contain substances that can have harmful effects.

Pomegranate usually doesn’t have side effects, but some people may have digestive tract symptoms. Allergic reactions to pomegranate have been reported.

Drinking pomegranate juice during pregnancy or while breastfeeding may be safe. Little is known about whether it’s safe to use other forms of pomegranate or other parts of the plant during pregnancy or while breastfeeding.
