What is Pomegranate?

Pomegranate is a tree. Various parts of the tree and fruit are used to make medicine.

Pomegranate is used for many conditions, but so far, there isn't enough scientific evidence to rate pomegranate as effective for any of them. We do know, though, that pomegranate does not seem to be effective for reducing the symptoms of chronic obstructive lung disease (COPD) or improving breathing in people with this condition.

Pomegranate is used for conditions of the heart and blood vessels, including high blood pressure, congestive heart failure (CHF), heart attack, "hardening of the arteries" (atherosclerosis), and high cholesterol. It is also used for conditions of the digestive tract, including diarrhea, dysentery, and tapeworm and other intestinal parasites.

Some people use pomegranate for flu, swelling of the lining of the mouth (stomatitis), gum disease, erectile dysfunction (ED), diabetes and a complication called acidosis, bleeding, and HIV disease. It is also used for preventing prostate cancer, obesity, and weight loss. Some women use pomegranate to cause an abortion.

Pomegranate is used as a gargle for sore throat, and it is applied to the skin to treat hemorrhoids.

Pomegranate (Punica granatum) is unique among plants. The only other plant that is closely related is a small tree commonly known as the pomegranate tree or Socotran pomegranate (Punica protopunica) and grows only on the Socotra island in Yemen.

Pomegranate has been used for thousands of years to treat a wide variety of diseases. It is in Greek, Hebrew, Buddhist, Islamic, and Christian mythology and writings. It is described in records dating from around 1500 BC as a treatment for tapeworm and other parasites.

Many cultures use pomegranate as a folk medicine. Pomegranate is native to Iran. It is primarily cultivated in Mediterranean counties, parts of the United States, Afghanistan, Russia, India, China, and Japan. You'll see pomegranate in some royal and medical coats of arms.

Possibly Ineffective for...

Insufficient Evidence to Rate Effectiveness for...

  • Hardening of the arteries (atherosclerosis). Early research suggests that drinking pomegranate juice might help to keep the arteries in the neck (carotid arteries) clear of the build-up of fatty deposits.
  • Clogged arteries (coronary heart disease). Some early research shows that drinking pomegranate juice might improve blood flow to the heart. However, drinking pomegranate juice does not seem to prevent narrowing of blood vessels in the heart (stenosis). Also, there is not enough information to know if drinking pomegranate juice helps to prevent heart disease-related events such as heart attack.
  • Dental plaque. Early research suggests that rinsing with pomegranate extract mouthwash for one minute once or twice daily reduces dental plaque.
  • Erectile dysfunction. Early research shows that drinking pomegranate juice daily for 4 weeks does not improve erectile dysfunction in men.
  • Muscle soreness after exercising. Early research suggests that drinking pomegranate juice twice daily for 15 days reduces muscle soreness after exercising in the elbow but not the knee.
  • High cholesterol (hyperlipidemia). Some studies show that pomegranate juice can lower total cholesterol and "bad" (LDL) cholesterol. However, other studies find no benefit. Pomegranate seed oil, but not pomegranate juice, may improve triglycerides and "good" (HDL) cholesterol levels.
  • High blood pressure (hypertension). Some research shows that drinking 50-200 mL of pomegranate juice daily for up to one year can lower systolic blood pressure (the top number) by 5% to 21%. Also, some research shows that drinking this amount of pomegranate juice can reduce diastolic pressure (the lower number), although other research shows no benefit. Drinking more than 240 mL of pomegranate juice daily does not seem to reduce blood pressure.
  • Metabolic syndrome. Early research suggests that drinking pomegranate juice daily for one month improves blood vessel function in adolescents with metabolic syndrome.
  • Muscle strength. Early research suggests that taking a specific pomegranate extract (POMx) twice daily improves muscle strength recovery after exercise.
  • Obesity. Early research suggests that taking a specific combination product (Xanthigen) containing pomegranate seed oil and brown marine algae reduces body weight in obese women with liver disease.
  • Gum disease. There is some evidence that painting the gum with pomegranate fruit peel extract in combination with gotu kola extract might improve gum disease.
  • Prostate cancer. Early research suggests that drinking pomegranate juice daily for up to 2 years might slow the progress of prostate cancer.
  • Inflamed and sore mouth (stomatitis). Applying a gel containing pomegranate extract to the gums improves symptoms in people with fungal infections in the mouth.
  • Sunburn. Early research suggests that taking pomegranate extract by mouth daily for 4 weeks does not reduce sunburn.
  • Sexually transmitted disease called trichomoniasis. Early research suggests that taking pomegranate extract might clear up trichomoniasis infections in women.
  • Intestinal worm infestations.
  • Diarrhea.
  • Dysentery.
  • Sore throat.
  • Hemorrhoids.
  • Menopausal symptoms.
  • Other conditions.
More evidence is needed to rate pomegranate for these uses.

How does Pomegranate work?

Pomegranate contains a variety of chemicals that might have antioxidant effects. Some preliminary research suggests that chemicals in pomegranate juice might slow the progression of atherosclerosis (hardening of the arteries) and possibly fight cancer cells. But it is not known if pomegranate has these effects when people drink the juice.

Are there safety concerns?

Pomegranate juice is LIKELY SAFE ffor most people when taken by mouth. Most people do not experience side effects. Some people can have allergic reactions to pomegranate fruit.

Pomegranate extract is POSSIBLY SAFE when taken by mouth or applied to the skin. Some people have experienced sensitivity to pomegranate including itching, swelling, runny nose, and difficulty breathing.

Pomegranate is POSSIBLY UNSAFE when the root and stems are taken by mouth in large amounts. The root contains a poison.

Special Precautions & Warnings:

Pregnancy and breast-feeding: Pomegranate juice is POSSIBLY SAFE for pregnant and breast-feeding women.

If you use pomegranate, stick with the juice during pregnancy or breast-feeding. Check with your healthcare provider first.

Low blood pressure: Drinking pomegranate juice can slightly lower blood pressure. Drinking pomegranate juice might increase the risk of blood pressure dropping too low in people who already have low blood pressure.

Allergies to plants: People with plant allergies seem to be more likely to have an allergic reaction to pomegranate.
