Hawthorne Berries are gathered
from the small tree Crataegus laevigata of the family Rosaceae. Also known
as Mayblossom and Whitehorn, Hawthorne was known to Dioscorides in the first century A.D.,
but was not widely used until recent times. The edible berries are often made into
marmalade, and herbal preparations made from the flowers, fruits, and leaves are very
prominent in contemporary European medicine. Currently about three dozen different
preparations containing extracts of Hawthorne are marketed in Germany.
Hawthorne is described in most modern herbals as a valuable
treatment for various heart ailments and circulatory disorders, as well acting as a mild
astringent to be used for treating sore throats. Hawthorne is most often used to protect
against the beginning stages of heart disease, for mild heart muscle weakness, for
pressure and tightness of the chest, and for mild arrhythmia. It is also used as a tonic
for an aging heart.
Standardized extracts improve myocardial and coronary
circulation, raising the myocardial tolerance for oxygen deficiency. Hawthorne is also
used for hypertension, nervous disorders and insomnia. It may potentate the action of
digitalis, and does potentate cardiotonic glycosides.
Hawthorne should not be used as a substitute for medical care
when an "organic cause" for one of the conditions listed is present, so cause
should be diagnosed prior to use.
Modern researchers have revealed some interesting properties of
Hawthorne and confirmed that Hawthorne contains compounds which support the heart and
circulatory system. Hawthorn works to dilate the blood vessels, especially the coronary
vessels, reducing peripheral resistance and thus lowering blood pressure and reducing the
tendency to angina attacks. Though Hawthorne's action is not immediate, but develops very
slowly, apparently it has a direct effect on the heart itself, especially in cases of
heart damage. Its toxicity is low as well, becoming evident only in large doses. It's
therefore a relatively harmless heart tonic which apparently yields good results in many
conditions where this kind of therapy is required.
Hawthorne contains leucoanthocyanins, flavonoids, hyperoside,
vitexin 2-rhamnoside, glycosylflavones, amines, catechols, phenolcarboxylic acids,
triterpene acids, sterols, inositol, PABA, saponins and purines. The main activity of
Hawthorne is derived from the potent mixture of pigment bioflavonoids, as well as
oligomeric procyanidins (dehydrocatechins) that seem to be particularly active.
Some of the flavonoid glycosides are thought to work in a similar way to digitoxin, having
a vasodilating effect that could be helpful in the treatment of angina. They also produce
marked sedative effects which indicate an action on the central nervous system.
A combination of several constituents seems to be directly
responsible for the increase in heart muscle contraction force, by blocking whatever is
reducing the contraction, for example, beta-blockers. The flavones help control the
intracellular Calcium ion concentration. Hawthorne berries also contain inositol, PABA,
purines, saponins, and B vitamins.
