PHARMACOLOGY
The berries are rich in flavonoids which have been shown to dilate peripheral and coronary blood vessels. This action helps alleviate hypertension and high blood pressure and reduce the severity and frequency of angina attacks. Hawthorne also is a rich source of procyanidins which have sedative and antispasmodic effects. The herb has also been shown to act as a cardiotonic, restoring both high and low blood pressure to normal. Hawthorne has been used in treating irregular heartbeats, spasms of the arteries (Raynaud's), and certain nervous disorders, such as insomnia.
