Active Compounds |
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 Hawthorn
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.

History |
Dioscorides, a Greek Herbalist, used Hawthorn in the first century
A.D. It went out fashion as a medicine until the 19th century, when
an Irish physician included them in a secret remedy for heart disease.
Years later, the medicine was found to be made from hawthorn berries,
which are still prescribed in folk medicine for a variety of heart-related
problems - among them high blood pressure and over-rapid heartbeat.

Description |
The hawthorn grows as either a shrub or a tree in England and continental
Europe. It is widely grown as a hedge plant. Its trunk or stem have
hard wood, smooth and ash-gray bark, and thorny branches. The small,
shiny leaves are dark green on top, light bluish green underneath,
and have three irregularly toothed lobes. The white flowers have
round petals and grow in terminal corymbs during May and June. The
fruit or haw is a 2 to 3 seeded, scarlet on the outside, yellowish
and pulpy on the inside.

Dosage |
Hawthorn extracts standardized for total bioflavonoid content (usually
2.2%) or oligomeric procyanidins (usually 18.75%) are often used.
Many people take 80-300 mg of the herbal extract in capsules or
tablets two to three times per day or a tincture of 4-5 ml three
times daily. If traditional berry preparations are used, the recommendation
is at least 4-5 grams per day. Hawthorn may take one to two months
for maximum effect and should be considered a long term therapy.
German physicians prescribe 1 teaspoon of hawthorn tincture upon
waking and before bed for periods of up to several weeks. To mask
its bitter taste, mix with sugar, honey, or lemon, or mix it into
an herbal beverage blend.
For an infusion, use 2 teaspoons of crushed leaves or fruits per
cup of boiling water. Steep 20 minutes. Drink up to 2 cups per day.

Safety |

cardiac medications or other drugs. There are no known contraindications
to its use during pregnancy or lactation. Large amounts of hawthorn
may cause sedation and/or a significant drop in blood pressure,
possibly resulting in faintness.
