Hawthorn is a thorny shrub or tree whose berries, leaves, and flowers have been used in European herbal medicine for centuries for cardiovascular health. It is one of the most well-studied herbs for heart failure and is approved by the German Commission E for declining cardiac performance. It is rich in flavonoids and procyanidins.
Hawthorn (Crataegus spp.) has Level A evidence for chronic heart failure (NYHA I-II). Over 7,000 patients studied in clinical trials.
Flavonoids and procyanidins inhibit PDE3, increasing cAMP and calcium availability. Coronary vasodilation via NO release. ACE inhibition.
