Used to treat heart failure

Hawthorn berry is best known for its historic usage in treating heart failure in conjunction with other conventional treatments. Heart failure occurs when the heart is unable to effectively pump blood. Several studies have suggested that hawthorn berries may have favorable effects in persons with heart failure without causing serious side effects. The majority of studies demonstrate improvements in heart function and symptoms of heart failure, such as shortness of breath and exhaustion.

Researchers believe that flavonoids found in hawthorn are responsible for these positive effects. However, there is some evidence that hawthorn may be hazardous in specific situations of heart failure. According to one study, taking it alongside conventional treatments increased the risk of heart failure progressing.
