Hawthorn For The Heart

 Hawthorne is a spiny shrub that has been traditionally used as a heart tonic in European herbal medicine. The primary active ingredients, the proanthocyanidins, are responsible for the red-to-blue color of many fruits, such as blueberries, grapes, and blackberries. The proanthocyanidins, and a related group of ingredients, the anthocyanidins, are known as potent antioxidants and for their protective effects on the heart and arteries.

The herbal medicine is made from an extract of the proanthocyanidin-rich leaves or berries blossoms of two primary species (Crataegus oxycantha and Crataegus monogyna). Other hawthorne species (Crataegus spp.) have long been used in both European herbal medicine and Traditional Chinese Medicine due to their similar effects.

Benefits

* Heart Tonic

* Lowers Blood Pressure

* Joint and Ligament Support

Heart Tonic

Hawthorne extract has been clinically shown to reduce serum cholesterol levels, prevent the deposit of cholesterol in the arterial walls, and prevent chest pain (angina) Hawthorne extract improves the blood supply to the heart by dilating the heart’s vessels. Hawthorne appears to improve the metabolism of the heart, thereby increasing strength and promoting regular contractions of the heart. In addition, hawthorne plays a role in the regulation of blood pressure, thereby promoting healthy cardiovascular function.

Hawthorne has exhibited cardiovascular support in the event and recovery of a heart attack. Due to hawthorne’s antioxidant activity; which is able to protect the cardiovascular system from free radical damage, studies have shown hawthorne extract to exert a protective effect when there is a lack of oxygen to the heart. Combined with the other effects of hawthorne already mentioned, hawthorne can be useful in the recovery period after a heart attack by strengthening the heart muscle, and improving blood flow and oxygen to the heart.

Blood Pressure

Hawthorne’s clinical effectiveness in reducing blood pressure can be explained by its ability to prevent certain substances from making the blood vessels contract. For example, procyanidins, the active ingredients in hawthorne, have been shown to inhibit an enzyme in the body that is a potent constrictor of blood vessels. Because blood pressure goes up when the muscles lining the blood vessels contract, hawthorne extract is able to play a role in regulation of blood pressure.

Warning: Use of hawthorne may affect pre-existing cardiovascular therapy, and strengthen the effect of cardiac glycosides, such as the drug digitalis. If your dog is taking prescription drugs or under a veterinarians care for heart problems, then consult your veterinarian.
