Here is some information from one of my text books. "The Healing Power of Nature's Herbs" by Michael T. Murray N.D.
Hawthorn Berries - spiny tree shrub native to Europe whose leaves berries and blossom contain many biologically active flavonoid compounds particularly anthocyanidins and proanthoccyanidins and cardiotonic amines.
Strong Vitamin "P" activity and an ability to increase intra-cellular vitamin C levels while stabilizing vitamin C (prevent oxidation)
Significant collagen stabilizing action (collagen maintains the integrity of tendons, ligaments, cartilage)
Clinically effective in reducing blood pressure (mild), angina attacks and serum cholesterol levels and in preventing deposition of cholesterol in artery walls.
Improves blood supply to the heart by dilating coronary vessels (repeatedly demonstrated)

This is a good reference bok for those seeking deeper understanding of how hawthorn works, it's dosage and toxicity.
