Hawthorn is a spiny, flowering shrub of the rose family. The species of hawthorn discussed here are native to northern European regions and grow throughout the world. The hawthorn leaf and flower are used to make liquid extracts, usually with water and alcohol. Dry extracts are put into capsules and tablets.


Historically hawthorn fruit has been used as an herbal remedy in the hope of improving heart, digestive and kidney problems.


More recently, hawthorn leaf and flower are being researched for their potential use as an herbal remedy for heart failure, a weakness of the heart muscle that prevents the heart from pumping enough blood to the rest of the body, which can lead to fatigue and limit physical activities.


Research studies indicate that hawthorn leaf and flower may be effective for milder forms of heart failure. There is not enough scientific evidence to determine whether hawthorn works for other heart problems.


Side Effects and Cautions

Hawthorn - Know What Herbs Do What


  • Hawthorn side effects can include upset stomach, headache, and dizziness.
  • Drug interactions with hawthorn have not been thoroughly studied. It was once thought that hawthorn interacted with the heart medicine digoxin. However, a very small study in people without heart conditions found no interaction, but evidence is limited.
  • Tell your health care providers about any complementary and alternative practices you use. Give them a full picture of what you do to manage your health to help ensure coordinated and safe care.  Complementary or alternative therapy should not be used in place of conventional medical care or to delay seeking that care.
