Pear tree

Pear is a tree. The pear fruit is used to make medicine.

People use pears for many conditions, including indigestion, diarrhea, constipation, nausea and vomiting, and liver scarring (cirrhosis), but there is no good scientific evidence to support these uses.

In foods, pears are eaten as fresh or preserved fruit, and used in cooking.

Is It Effective?

Effectiveness header

NatMed Pro rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, Ineffective, and Insufficient Evidence to Rate.

Insufficient evidence
  • Athletic performance. Early research shows that taking a carbohydrate supplement obtained from pears before and during a long-distance cycle ride seems to improve overall cycling time in athletic men.
  • Hangover. Early research shows that drinking Korean pear juice 30 minutes before drinking alcohol seems to help reduce hangover symptoms 15 hours later by a small amount.
  • Obesity. Early research shows that eating pears 3 times daily between meals while on a calorie-controlled diet might help reduce weight by a small amount over 12 weeks.
  • Cancer.
  • An infection of the intestines that causes diarrhea (cholera).
  • Constipation.
  • Diarrhea.
  • Fevers.
  • Fluid retention.
  • Indigestion.
  • Nausea and vomiting.
  • Liver scarring (cirrhosis).
  • Obesity.
  • Other conditions.

More evidence is needed to rate the effectiveness of pear for these uses.
