This hawthorn monograph provides basic information about hawthorn—common names, usefulness and safety, and resources for more information.
- Hawthorn is a flowering shrub or tree of the rose family. It is native to Europe and grows in temperate regions throughout the world.
- Historically, hawthorn has been used for heart disease as well as for digestive and kidney problems. It has also been used for anxiety.
- Extracts from the hawthorn leaf, flower, or berry may be sold as capsules, tablets, or liquids.
Hawthorn in Health Research
- Hawthorn has been studied for heart failure in people. Heart failure is a condition in which the heart can’t pump as much blood as it should.
- Not much is known about hawthorn for any other health conditions as there is little or no evidence.
Hawthorn Research Summary
- Although some older, short-term studies suggested that hawthorn may have benefits in patients with heart failure, two longer term studies completed in 2008 and 2009—including a 2-year trial involving almost 2,700 people in 13 European countries—did not confirm these benefits. In these studies, unlike some of the older ones, patients were given hawthorn in addition to the recommended conventional treatments for heart failure.
- In most studies of hawthorn for heart failure, no serious safety problems have been reported. However, in one study, patients taking hawthorn were more likely than those taking a placebo (an inactive substance) to have their heart failure get worse soon after the study started. The reason for this is not clear, but one possibility is that hawthorn might have interacted with drugs the patients were taking.
- Side effects of hawthorn can include dizziness, nausea, and digestive symptoms.
- Hawthorn may interact in harmful ways with drugs, including some heart medications. If you’re taking medication and you’re considering using hawthorn, consult your health care provider.
