What should I watch out for?

Hawthorn seems safe for most adults when used for a short time. The biggest risk with this remedy is that if you use hawthorn instead of medical treatment for serious conditions, you might increase your risk of death.

Hawthorn appears to improve the heart's pumping ability. However, there are many drugs for heart failure (such as ACE inhibitors) that are more effective, and have been proven to save lives. Hawthorn has not been shown to provide the same benefit.

Talk with your healthcare provider before taking this remedy if you have any heart condition. Do not try to treat heart failure or other heart conditions by yourself. You should take hawthorn only if your healthcare provider approves and tells you that you have no medically significant heart problems.

If you need emergency care, surgery, or dental work, tell the healthcare provider or dentist you are taking this medicine.
