Health Benefits of Hawthorn Leaf Extract
Diabetes and blood sugar
Hawthorn evokes a potent anti-hyperglycemic capacity in streptozotocin-induced diabetic rats.
J Herb Pharmcother. 2003. The hypoglycemic effect of an aqueous extract of hawthorn leaves (Crataegus oxyacantha) was investigated in normal and streptozotocin (STZ) diabetic rats. After a single dose or 9 daily doses, oral administration of the aqueous hawthorn extract produced a significant and dose-dependent decrease on blood glucose levels in STZ diabetic rats, but had no effect on blood sugar levels in normal rats. No changes were observed in basal plasma insulin concentrations after treatment in normal or STZ diabetic rats.

Heart failure
Crataegus oxyacantha (Aubepine, Hawthorn), was used by European herbalist in the first century A. D. It went out fashion as a medicine until the 19th century for heart disease. The leaves, flowers, and berries of hawthorn contain a variety of bioflavonoid-like complexes that appear to be primarily responsible for the cardiac actions of the plant. Bioflavonoids found in C. oxyacantha include oligomeric procyanidins (OPCc), vitexin, quercetin, and hyperoside. The action of these compounds on the cardiovascular system has led to the development of leaf and flower extracts. Hyperoside is the marker for quality control.
