Background

Hawthorn is a flowering shrub in the rose family. Common species include Crataegus monogyna, Crataegus laevigata, Crataegus oxyacantha, and Crataegus mexicana.

The hawthorn leaves, berries, flowers, and roots are used as medicine. They contain chemicals called flavonoids, which have antioxidant effects. Hawthorn also seems to improve blood circulation and affect blood flow from the heart.

People most commonly use hawthorn for chest pain, heart failure, blood circulation problems, high blood pressure, anxiety, and many other conditions, but there is no good scientific evidence to support these uses.
When taken by mouth: Hawthorn is possibly safe when used in doses up to 1800 mg daily for up to 16 weeks. There isn't enough reliable information to know if hawthorn is safe when used for longer than 16 weeks. Hawthorn is usually well-tolerated.

When applied to the skin: There isn't enough reliable information to know if hawthorn is safe or what the side effects might be.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There isn't enough reliable information to know if hawthorn is safe to use when pregnant or breast-feeding. Stay on the safe side and avoid use.

Heart disease: Hawthorn can interact with many prescription drugs used to treat heart disease. If you have a heart condition, don't use hawthorn without talking to your healthcare provider.

Surgery: Hawthorn might slow blood clotting and increase the risk of bleeding during and after surgery. Stop using hawthorn at least 2 weeks before a scheduled surgery.
