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.

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.
