Functions of Product
While many hawthorn extracts contain 2% vetexin extracted from hawthorn berries, there is Oligomeric Procyanidins in the leaves and flowers. Extracting from this different plant part provides up to 10 times more of the key active bioflavonoids necessary for efficacy.
Hawthorn extract has been shown to support efficient heart muscle metabolism by improving its oxygen and energy utilization.
It is taken orally to relieve chronic heart conditions——primarily congestive heart failure, but also angina and arrhythmias. Chemicals in it may act directly on the heart muscle to increase the force of heartbeats and on the blood vessels to relax the arteries around the heart. It may also lengthen the time that the heart rests between beats. It may also work indirectly by widening blood vessels close to the surface of the skin. As a result, it may also help to lower blood pressure. Due to its multiple effects on the heart, it should not be taken before its use has been discussed with a doctor.
Hawthorne (Crataegus Oxyacantha) is known as a botanical heart tonic and is recommended for angina, irregular heartbeat, high blood pressure, congestive heart failure, hypertension, coronary heart disease, high cholesterol, nervous disorders, insomnia and Raynaud's Syndrome.
Pictures about us
The extract of hawthorn is the brown-yellow powdery substance extracted from dry and ripe fruits of Crataegus pinnatifida Bge. Var. Major N.E. Br. Or Crataegus pinnatifida Bge. The main active ingredients are various organic acids. With Xiaoshi Jianwei, anti-inflammatory cough, lowering blood pressure, lowering blood pressure, increase coronary blood flow and prevention of coronary heart disease, angina and other effects and anti-cancer, anti-cancer effect.In the gastric juice conditions, hawthorn extract can eliminate the synthesis of nitrosamine precursor material, which can block the synthesis of nitrosamines. Hawthorn acetone extract on the mutagenic effect of aflatoxin B1 has a significant inhibitory effect, hawthorn may be useful for the prevention of liver cancer.
Hawthorn flavonoids, organic acids, sugars, tannins, protein, vitamins, amino acids and so on.

1. What is its main role?
Hawthorn extract can promote the secretion of digestive enzymes in the stomach to promote digestion. Contains lipase can promote the decomposition of fat digestion; contains a variety of organic acids, vitamin C can improve pepsin activity, promote protein digestion. Hawthorn extract on the regulation of gastrointestinal function, hyperactivity of rabbit duodenal smooth muscle was inhibited, while the relaxation of gastric smooth muscle in rats with mild increase in contraction
2. What is the effect on heart disease?
Hawthorn has enhanced myocardial contractility. Increase cardiac output, slow down the rhythm of the role. Hawthorn extract in vivo, isolated toad cardiac contractility increased, and the duration of a long time. The triterpenic component, maslinic acid, has a recovery effect on the cardioplegia of the fatigue of the toad heart, but its duration is short. In this case,
3. Is cancer effective?
Hawthorn mice Ehrlich ascites carcinoma cells significantly inhibited. The decoction of Hawthorn seed decoction on human cervical cancer JTC-26 in vitro inhibition rate of 50% to 70%. Hawthorn tablets decoction can extend the life of transplanted tumor animals. The results showed that the survival rate of cancer cells decreased significantly when the dose of hawthorn extract was 4 ~ 8μg / ml, and the colony formation rate of cancer cells was significantly inhibited under the dose of 8 ~ 10μg / ml. Normal human cells no significant effect.
