Hawthorn Berry

I need some information on Hawthorn Berry and it's medicinal properties and what it's used for as an herbal cure.

Thomas Bartram in "Encyclopedia of Herbal Medicine" (available at Richters) lists the actions of hawthorn berry as: positive heart restorative, coronary vasodilator, antispasmodic, antihypertensive, adaptogen ( a substance that helps the body to adapt to a new strain or stress by stimulating the body's own defensive mechanism), diuretic, sedative to nervous system, cholesterol and mineral solvent.
Bartram states the uses as: to increase blood flow through the heart; strengthens the heart muscle without increasing the beat or raising blood pressure; enhances exercise duration; myocarditis; improves circulation in coronary arteries; atheroscleosis, atheroma, thrombosis, rapid heart beat, paroxysmal tachycardia, fatty degeneration, angina; enlargement of the heart from overwork, over-exercise or mental tension; alcoholic heart, Buerger's disease, intermittent claudication (pain in legs when walking due to deficient blood supply to the muscles), risk of infarction, dizziness, mild to moderate hypertension, insomnia. Used by sportsmen to sustain the heart under maximum effort.
