Portulaca oleracea is rich in nutrients such as dihydroxyethylamine, malic acid, glucose, calcium, phosphorus, iron, and vitamin E, carotene, vitamin B, and vitamin C. Portulaca oleracea has a salient feature in nutrition, and its omega-3 fatty acid content is higher than that of humans and plants. Omega-3 fatty acids can inhibit the absorption of cholesterol by the human body, lower the blood cholesterol concentration, and improve the elasticity of the blood vessel wall, which is beneficial to the prevention and treatment of cardiovascular diseases.

Function & Application

Edible effect

1, diuretic swelling. Lowering blood pressure Portulaca oleracea contains a large amount of potassium salt, which has a good effect of reducing water swelling; potassium ions can also directly act on the blood vessel wall, so that the blood vessel wall is dilated, preventing the thickening of the arterial wall, thereby lowering blood pressure.

2. Eliminate dust and poison. Prevention and treatment of ulcerated purslane can eliminate dust and poison, prevent phagocytic cell degeneration and necrosis, prevent lymphatic inflammation and prevent fibrotic changes, prevent the formation of sputum nodules, and have certain curative effect on vitiligo; dentate also contains more Carotene can promote the healing of ulcer disease.

3, Sterilization and anti-inflammatory. Purslane has a strong inhibitory effect on Shigella, Salmonella typhi and Escherichia coli, and can be used for the adjuvant treatment of various inflammations. It is known as "natural antibiotics".

4, Prevention of heart disease. Purslane contains a rich Y-3 fatty acid, which can inhibit the production of serum cholesterol and triglyceride in human body, help increase the synthesis of prostaglandins in vascular endothelial cells, inhibit thrombocytosis of platelets, and decrease blood viscosity. It promotes blood vessel dilatation and can prevent platelet aggregation, coronary spasm and thrombosis, thereby preventing heart disease.

Pharmacological action

1, Antibacterial effect
Ethanol extract has a high inhibitory effect on Escherichia coli, Proteus, Shigella, Typhoid, and Salmonella typhimurium. It also inhibits Staphylococcus aureus and fungi such as A. sinensis and Mycobacterium tuberculosis. Mild inhibition of Pseudomonas aeruginosa.

2, The role of the uterus
Clinical and animal experiments have shown that purslane has a contractile effect on the uterus.

3. Effect on smooth muscle
The purslane preparation has a significant contraction effect on the isolated rat ileum, which is similar to the action of prostaglandin E and neostigmine excitatory intestinal smooth muscle.

4, Other effects
Decoction has an inhibitory effect on isolated frog heart and isolated guinea pig small intestine. Anesthetized dogs were given an intravenous injection of 20% decoction 3 ml/only, which had no significant effect on their blood pressure. Water-soluble and fat-soluble extracts can prolong the life of certain alloxan-induced diabetic rats and rabbits, but do not affect blood glucose levels, which may be due to an improvement in the disorder of lipid metabolism in animals. Purslane has a significant contraction effect on blood vessels. It can also promote the growth of epithelial cells and facilitate ulcer healing.
