Crataegus laevigata is one of hundreds of species of hawthorn, a
small, flowering shrubby tree in the rose family that is native to
Europe. Also known as English hawthorn, this species is a popular garden
specimen often grown as a hedge or border plant. It is also the species
that provides the leaves and flowers used to produce medicinal
preparations approved for heart conditions in Europe by the German E
Commission.
Hawthorn leaf and flower contain potent antioxidant compounds called
oligomeric procyandins, the concentration of which are typically
standardized in dietary supplements marketed in North America. The herb
may also be enjoyed prepared as a simple tea. However, if you have a
known heart condition or take medications for high blood pressure or
irregular heart rhythm, check with your doctor before using hawthorn
because the herb may increase the effects of these drugs.
