Hawthorn is traditionally known, particularly in Chinese Medicine, for its heart-strengthening properties. Recent scientific studies have confirmed Hawthorn's many different positive effects on the heart and the herb has become a popular prescription medicine in Germany for heart failure.
In addition to treating congestive cardiac failure, Hawthorn is used for heart arrhythmias, hypertension and atherosclerosis. It also exhibits antioxidant, antiinflammatory, antiviral and lipid-lowering activity, and is used to strengthen connective tissue, decrease capillary fragility and prevent collagen destruction of joints.
Hawthorn is best avoided during pregnancy due to a lack of studies demonstrating its safety.
