【Pharmacological effects】
1. Promoting digestion Hawthorn contains lipase, which can promote fat digestion, increase the secretion of gastric digestive enzymes, and promote digestion. It has a certain regulatory effect on gastrointestinal function, inhibits the hyperactive rabbit duodenal smooth muscle, and has a mild enhanced contraction effect on the relaxed rat gastric smooth muscle. The extract and aqueous solution of hawthorn acid have a significant inhibitory effect on the contraction of isolated gastrointestinal smooth muscle of rabbits and mice induced by acetylcholine and Ba\2, and have a contraction-promoting effect on the gastric smooth muscle of rats in a relaxed state.

2 Effects on the cardiovascular system (1) Effects on the heart Hawthorn acid extract can enhance the contraction force of the heart of toads in vivo and in vitro, and the duration is long. Hawthorn acid can restore the beating of the heart of toads that are tired and weak. The triterpene acids contained in hawthorn can improve coronary circulation and compensate for coronary artery failure, achieving a cardiotonic effect. Hawthorn preparations can cause significant and lasting dilation of the coronary arteries in the heart of guinea pigs and enhance cardiac capacity. 4g/kg of hawthorn extract was injected intravenously into guinea pigs for 6 consecutive days, which had a certain protective effect on myocardial damage caused by isoproterenol. Hawthorn can increase coronary flow, reduce myocardial oxygen consumption, and have a protective effect on myocardial ischemia and hypoxia. The intravenous injection of yam extract and total flavonoids into dogs can increase coronary blood flow by 37.5%, and myocardial oxygen consumption increases slightly at first, but then gradually decreases. Yam flavonoids can reduce the scope of myocardial infarction and alleviate S-T segment changes in the experimental acute myocardial infarction model. Yam fluid extract has a certain protective effect on acute myocardial ischemia caused by posterior pituitary hormone and isoproterenol in animals. After feeding dogs with yam (containing procyanidin oligomers), their left ventricular blood flow can increase for several hours, and the maximum increase can reach 70% of the normal blood flow. Intravenous injection of procyanidin oligomers into cats can also increase their cardiac blood flow in a dose-dependent manner and slightly reduce arterial blood pressure. Hawthorn extract has a certain inhibitory effect on arrhythmia caused by the posterior pituitary cord. Triterpenoid acids can increase coronary blood flow, improve myocardial sensitivity to the effects of cardiac glycosides, increase cardiac output, reduce myocardial irritability and conductivity, and have anti-ventricular fibrillation, atrial fibrillation and paroxysmal arrhythmia effects.

(2) Antihypertensive effect Experiments have shown that hawthorn has a long-lasting antihypertensive effect. Intravenous administration of hawthorn ethanol extract can slowly reduce the blood pressure of anesthetized rabbits for 3 hours. Intravenous injection of hawthorn total flavonoids 10mg/kg can reduce the blood pressure of cats by 40%, maintaining for 5-10 minutes. Its total extract also has a relatively obvious central hypotensive effect on rabbits and cats. Intravenous injection, intraperitoneal injection, and duodenal administration of northern hawthorn flavonoids, triterpenes and hydrolyzates have shown varying degrees of antihypertensive effects on the blood pressure of anesthetized cats. The blood pressure reduction rate of hawthorn hydrolyzate 20mg/kg intraperitoneal injection, 5-25mg/kg intravenous injection, respectively, was 26%, 32.5%-44.5%; hawthorn flavonoids 25mg/kg, 50mg/kg intraperitoneal injection, 12.5mg/kg, 25mg/kg intravenous injection, 100mg/kg, 150mg/kg intraduodenal administration, the blood pressure reduction rate was 45.3%, 66.6%, 52%, 30%, 38.1%, 39.2%, respectively, and the maintenance time was 240min, 130min, 100min, 81min, 540min, 540min. Hawthorn triterpene acid has the strongest antihypertensive effect in the range of 20-40mg/kg, and the antihypertensive effect does not increase accordingly when the dose is increased. When hawthorn flavonoids and triterpenic acid hydrolysates were compared by intravenous injection at the same dose (25 mg/kg), triterpenic acid had the most obvious antihypertensive effect; but the dose of flavonoids that produced a significant antihypertensive effect was the lowest.

3. Lipid-lowering effect Oral administration of hawthorn plant extract and alcohol extract at 0.5 mg/kg can increase the proportion of lecithin in the blood of rabbits with atherosclerosis and reduce the deposition of cholesterol and lipids in organs. Oral administration of southern hawthorn powder has the effect of reducing serum total cholesterol and β-lipoprotein in experimental hyperlipidemia rabbits, and the reduction value of serum β-lipoprotein is similar. 15% and 30% hawthorn extracts have a lipid-lowering effect on young rats, among which 30% hawthorn extract is more significant. After guinea pigs take hawthorn decoction, they have an inhibitory effect on the activity of cholesterol-containing enzymes, and can reduce the activity of hydroxymethylglutarylase A reductase in liver cell microsomes and small intestinal mucosa by about 70% and 67%, respectively. Shanlihong water extract can significantly reduce serum total cholesterol content, and its effect is significantly greater than pantethine, and can significantly increase serum HDL-C, HDL2-C, and HDL3-C concentrations. Its effect may be achieved by increasing the concentration of HDL and its subcomponents in serum and increasing cholesterol excretion.

4. Antioxidant effect Hawthorn water extract can scavenge O/2 free radicals, inhibit lipid peroxidation in mouse liver, and reduce O/2-induced hyaluronic acid depolymerization.

5. Effect on immune function The injection made by decoction and alcohol precipitation of hawthorn was subcutaneously injected for 9 consecutive days, which can significantly enhance the serum lysozyme activity, serum hemagglutination antibody titer, heart blood T lymphocyte E rosette formation rate and T lymphocyte transformation rate of rabbits, indicating an immune enhancement effect.

6. Antibacterial effect Hawthorn has a strong antibacterial effect on Shigella dysenteriae, Shigella flexneri, Shigella sonnei, etc.; against Staphylococcus aureus and group B streptococci. Escherichia coli, Proteus, Bacillus anthracis, Corynebacterium diphtheriae, Salmonella typhi, Pseudomonas aeruginosa, etc. also have antibacterial effects; generally, the effect on Gram-positive bacteria is stronger than that on Gram-negative bacteria.

7. Anti-cancer effect Under the pH conditions of gastric juice, hawthorn extract can eliminate the precursors of synthetic nitrosamines, that is, it can block the synthesis of nitrosamines. Hawthorn extract has a significant blocking effect on the synthesis of methylbenzyl nitrosamine in rats and mice. The acetone extract of hawthorn has a significant inhibitory effect on the mutagenic effect of aflatoxin B1-induced TA98 frameshift type and TA100 base substitution mutants. The experiment showed that hawthorn has a significant inhibitory effect on the mutagenic effect of aflatoxin BI. It shows that hawthorn may be meaningful in preventing liver cancer.

8. Other effects Hawthorn 2.5g/kg intraperitoneal injection can significantly prolong the duration of pentobarbital sodium sleep in mice. Hawthorn has the effects of contracting the uterus, promoting uterine recovery, and relieving pain.

9. Toxicity The LD50 of the polymerized flavanoid components of hawthorn for intraperitoneal and subcutaneous injection in mice is 130mg/kg and 300mg/kg respectively; 10% hawthorn extract was orally administered to male rats and mice, and soon sedation occurred, and 30 minutes later, the mice died of respiratory failure, the LD50 of mice was 18.5ml/kg, and the LD50 of rats was 33.8ml/kg; 10% hawthorn total saponins also did not cause hemolysis in rabbits.

The roots (hawthorn roots), wood (hawthorn wood), stems and leaves (hawthorn stems and leaves), and seeds (hawthorn core) of the above two plants are also used for medicinal purposes. Each is detailed in the article.

【Clinical Application】
①Treatment of tapeworms

Use 2 kilograms of fresh hawthorn (half a kilogram of dry product, less for children), wash and remove the core, start snacking at 3 p.m., finish eating at 10 p.m., and fast for dinner. The next morning, add 2 ounces of betel nut to water and boil it to 1 tea cup. Take it once and rest in bed. When you feel the urge to defecate, try to hold on for a while before defecating, and the complete tapeworm will be expelled. In winter, you should sit on a warm water toilet to defecate to prevent the insects from shrinking when exposed to cold and unable to be completely discharged. All 40 cases were observed to be effective.

②Treatment of acute bacillary dysentery

Use 20% hawthorn decoction, add sugar to taste, take 200 ml each time (reduced for children), 3 times a day, 7 to 10 days as a course of treatment. 24 cases were treated and all were effective. It was also useful to decoct 2 ounces of hawthorn and treat 30 cases of mild and medium bacillary dysentery. Except for 3 cases that were ineffective, all were cured or improved. Or use 1 tael each of heat-generating hawthorn tablets, add 500 ml of water and boil for 5 minutes, take it in 2 times (reduced for children), 4 to 6 days is a course of treatment, which is also effective.

③Used to lower serum cholesterol

Take 1 tael of hawthorn and 2 taels of wintergreen every day, decoction in 2 times. Observing 20 cases, the average serum cholesterol before treatment was 253.2 mg%, which dropped to 207 mg% after treatment, with an average decrease of 46.2 mg% per case. After statistical analysis, the difference was very significant. Serum cholesterol dropped below 200 mg% in 11 of 20 cases, with an average decrease of 62.9 mg% per case. It is believed that the role played by hawthorn is the main one, because the effect of Ilex in lowering serum cholesterol is quite inconsistent in various places, and it is difficult to be sure at present; and 4 cases in this group of cases had taken hawthorn alone without using Ilex. The effect was achieved. The average serum cholesterol before taking the medicine was 259.7 mg%. After taking the medicine for a reexamination at the 6th week, it dropped to 214 mg%.

In addition, taking hawthorn flowers and leaves as an infusion can lower blood pressure.

[Medicinal Part] It is the fruit of hawthorn or wild hawthorn, a plant of the Rosaceae family.
