Hawthorn
By Mayo Clinic staff
Latin name
Crataegus species
Other name
Whitethorn
Popular uses
Hawthorn is used to help prevent chest pain (angina) and improve cardiac function in people with chronic mild heart failure.
What the research shows
U.S. studies of hawthorn have been short-term and inconclusive. However, European studies indicate hawthorn may expand the blood vessels, allowing more oxygen and blood to reach the heart. This strengthens the heartbeat, slightly increasing its speed. By dilating the blood vessels, hawthorn seems to help circulation and can reduce blood pressure.
Possible side effects
Typically none with proper use. However, if you experience any adverse side effects or reactions, see your doctor.
Cautions
Hawthorn is intended for long-term treatment of the early stages of congestive heart failure. Use only under a doctor's supervision. If you have concerns about chest pain or the health of your heart, see your doctor for a complete examination. Heart disease is a serious illness, and you shouldn't treat any symptoms yourself or ignore the well-established benefits of prescription drugs.
Available forms
Liquid and dry extracts from a combination of hawthorn flowers, leaves and fruits.
Be sure to select a preparation that includes all three components or a combination of leaves and flowers. Extracts from the leaf, berry or flowers alone are not as effective.
Typical dosage
The potency of commercial products varies. Follow the manufacturer's instructions. You typically take hawthorn for up to 6 weeks before you experience benefits. Talk to your doctor about what dosage is appropriate for you.
Active ingredients
Flavonoids, especially oligomeric procyanidans.
