Hawthorn Extract

The medicinal properties of hawthorn (Crataegus spp., a genus comprising approximately 300 species) have been utilized by many cultures for a variety of therapeutic purposes for many centuries. 

Hawthorn has been traditionally used as a diuretic for kidney and bladder disorders, to treat stomach ache, stimulate appetite, and improve circulation and lower blood lipids. Other traditional uses for hawthorn include treatment of stress, nervousness, and sleep disorders. Studies in animals suggest that hawthorn extracts exert effects on the CNS, including relief of anxiety and pain.

Preparations containing hawthorn remain popular in Europe for the treatment of high or low blood pressure, tachycardia, or arrhythmias, with the revised Complete German Commission E Monographs approving the use of leaves and flowers for the treatment of long-term heart failure.
