The pharmacological effects of thistle flower

Pharmacological effects

1. Effects on the cardiovascular system. Sputum aqueous solution has a slight excitatory effect on isolated frog hearts and blocks the heart conduction system. Hirudin, quercetin, and ecdysteroids can also increase the amount of contraction and output of isolated and inactive frog hearts, and can slow heart rate. Quercetin can dilate coronary vessels and improve myocardial circulation. Musk Aphid can contract the blood vessels of the lower extremities and rabbit ears. 2. The limpet flower liquid and limpet flower tincture have temporarily significant blood pressure lowering effect on anesthetized dogs and cats. Musk and its preparations have antihypertensive effect, and quercetin can also reduce blood pressure in a short time.

2. The effect of blood lipid on quercetin subcutaneous injection of 10mg, can effectively reduce the experimental hypercholesterolemic rats liver, aorta and blood cholesterol levels, and increase the stability of cholesterol-protein complexes. The prevention and treatment of experimental arteriosclerosis.

3. Effects on capillaries Hirudin and its glycosides quercetin can maintain the normal resistance of capillaries, reduce vascular permeability, and restore normal elasticity of capillaries bleeding due to increased brittleness. Quercetin can increase the skin capillary resistance of guinea pigs and rats, reduce vascular permeability, and its capillary stability is 1/3 stronger than that of musk. Continuous application of a large number of musk deer and quercetin can prevent rat lung hemorrhage caused by decompression.

4. Anti-inflammatory effects Hirudin and quercetin can inhibit paw edema caused by histamine, egg white, serotonin, formaldehyde, and polyvinyl-pyrrolidone, and hyaluronic acidase-induced ankle and foot edema. Musk Toad can significantly inhibit traumatic edema in rats and prevent conjunctivitis, auricular inflammation and pulmonary edema. For rabbits caused by mustard oil conjunctival edema, only a slight inhibitory effect, such as the citronella dissolved in propylene glycol, to prevent inflammation better. 5. Intravenous injection of muscats can inhibit allergic skin and joint inflammation caused by rabbit serum. The sodium salt of saponin sulfate can accelerate the recovery of hindlimb thrombophlebitis caused by injection of turpentine.

5. Antispasmodic and antiulcer effects quercetin can reduce the tension of intestinal and bronchial smooth muscles, and its antispasmodic effect is 5 times stronger than that of musk. Quercus sinensis can reduce gastric motility in rats and relieve intestinal smooth muscle spasm caused by barium chloride. Subcutaneous injection of 5 to 10 mg/kg of muscimol can significantly reduce the number of lesions in gastric ulcers caused by ligation of the pylorus in rats. The efficacy of reflex gastric ulcer is stronger than that of Kailin. Sputum aqueous solution (with a small amount of carmine A) into the rabbit intestine, can stimulate the intestinal mucosa to increase the exudate.

6. Anti-pathogenic microorganisms Acting squid water infusion (2:5), Trichophyton mongolicus, Brassica chinensis, Oxytogloscus aurantiacus, Folliculus verrucaria, Star slave in vitro The phytopathogenic fungi such as cataplasm are all inhibited to varying degrees. In test tubes, quercetin and quercetin have antibacterial effects on certain bacteria; they also show inhibitory effects on the virus.

7. Other effects Musk Aphid has a protective effect on X-ray exposure. Eucalyptus contains hemagglutinin, which has agglutination on blood cells. Large doses of elixir can cause some inhibition of central reflexes. It is generally believed that musk carp cannot be absorbed orally, so it cannot be determined whether oral treatment is available. However, there are also reports that can still be absorbed after oral administration.
