Hawthorn Berries ( Crataegus oxyacantha ) ( Crataegus species )

Hawthorn berries have a long history in both folk medicine and clinical medicine as a heart tonic. The herb is typically used to improve cardiovascular function, as it increases the supply of blood to the heart muscle, resulting in enhanced circulation throughout the body. It has shown to have positive effects upon stabilizing angina pectoris, as well as aiding recovery from heart attacks.

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. Hawthorn seems to inhibit angiotensin converting enzyme (ACE) and reduce production of the potent blood vessel-constricting substance angiotensin II. This reduces resistance in arteries and improves extremity circulation. The bioflavonoids in hawthorn are potent antioxidants. Numerous double-blind clinical trials have confirmed hawthorn is beneficial for persons with serious heart conditions.

Folk usage and modern clinical trials indicate benefit for congestive heart failure.

No adverse drug reactions have been reported: Weihmayr 1996

Grieve's classic 'A Modern Herbal': 'Mainly used as a cardiac tonic in organic and functional heart troubles. Both flowers and berries are astringent and useful in decoction to cure sore throats. A useful diuretic in dropsy and kidney troubles. The leaves have been used as an adulterant for tea. An excellent liquer is made from Hawthorn berries with brandy.'

Usage: 1 tsp. 2 to 3 times a day depending on condition.
