Hawthorn (Crataegus oxyacantha) is a spiny bush that grows to 25 feet in height, bearing leaves that are divided into three to five lobes and strong-smelling flowers that grow in large bunches. The leaves and flowers contain the flavonoids, hyperoside and vitexin-rhamnoside as well as oligomeric proanthocyanidins. The leaves and flowers are dried, cut, and milled.

Health Benefits

Hawthorn may aid in improving heart function (e.g., maximal workload and left ventricular ejection fraction) and preventing symptoms of early chronic heart-failure.1,2 These symptoms may include weakness, fatigue, and palpitations.2 Hawthorn may improve the symptoms of cardiac insufficiency, particularly heart rate and blood pressure.3 Hawthorn may improve cognitive function in the elderly.4 Hawthorn may also improve mild and moderate anxiety disorders and lower bad cholesterol (LDL cholesterol) and HbA1C (glycated hemoglobin) when used in combination with other herbs.5,6
