The role and efficacy of purslane
Purslane, the whole plant of the purslane plant, also known as longevity vegetable, ant vegetable, dimalai, etc., is sour and cold in nature. Role, attending heat dysentery pus and blood, hot stranguria, vaginal discharge, pain, swelling and malignant sore, erysipelas. Purslane can be used both as medicine and edible. It is one of the 78 kinds of wild plants with the same origin as medicine and food designated by the Ministry of Health of my country. Folks often have the habit of eating this wild vegetable, either as a salad, or mixed with flour for pancakes, or as a stuffing, which has a unique flavor.
The efficacy and role of purslane
1. Antibacterial effect
Purslane has a broad-spectrum antibacterial effect, but due to the different active ingredients contained in different extracts, its antibacterial spectrum is different, such as ethanol extract of purslane Escherichia coli, Proteus, Shigella dysenteriae, typhoid fever It has a high inhibitory effect on paratyphoid bacillus, etc., and the decoction has inhibitory effect on Shigella dysentery, Shigella song's, Shigella flexneri, etc.
2. Anti-inflammatory effect
Portulaca oleracea water extract can effectively inhibit the swelling of mouse auricle caused by xylene and croton oil, and has anti-inflammatory effect. Reduce congestion, inhibit capillary permeability and reduce inflammation.
3. Anti-hypoxia effect
The ethanol extract of purslane can significantly reduce the oxygen consumption of mice, can significantly shorten the hypoxic convulsion time, prolong the survival time and improve the survival rate of mice. Its anti-hypoxia mechanism may include two aspects: First, by promoting the activity of key enzymes of anaerobic glycolysis in mice, it can alleviate the cell damage caused by energy metabolism disorders caused by hypoxia. The second is to protect mitochondria from hypoxia damage by inhibiting the lipid peroxidation of myocardial mitochondrial phospholipids and improving the activity of respiratory chain enzymes.
4. Hypoglycemic effect
Portulaca oleracea water extract can reduce blood sugar in diabetic mice, improve symptoms, and have the effect of assisting in lowering blood sugar. Its mechanism of action is related to inhibiting islet cell damage, promoting its repair, and promoting insulin secretion.
5. Anti-tumor effect
In vitro experiments have shown that purslane polysaccharide can inhibit the proliferation of SMMC721 liver cancer cells, and its tumor suppressor effect is positively correlated with the dose. In vivo administration, purslane polysaccharide has inhibitory effect on S180 solid tumor and ascites tumor, which mainly achieves anti-tumor effect by enhancing the body's immune function and directly inhibiting the division of tumor cells.
6. Lowering blood lipids
Purslane can reduce the levels of triglyceride, total cholesterol and LDL-C in the serum of hyperlipidemia, which is mainly due to the unsaturated acids α-linolenic acid and W-3 contained in purslane Fatty acids, promote cholesterol transport and metabolism, while avoiding increased levels in the blood.
7. Analgesic effect
In the writhing experiment in mice, purslane can significantly reduce the number of writhing reactions in mice, and in the hot plate experiment, the pain threshold of mice was significantly increased, suggesting that purslane has obvious analgesic effect. For further study.
8. Enhance immunity
According to literature records, it is shown that purslane can significantly improve the proliferation ability of normal rabbit lymphocytes and phytohemagglutinin-induced lymphocytes, thereby improving the immune function of the body.
9. Anti-allergic
Li Xiangli et al. used bee acupuncture to stimulate the feet of animals to establish an animal model of local allergic reaction. Taking the allergic symptoms such as redness, swelling, heat and pain as indicators, they observed the anti-allergic effect of purslane. The local allergic reaction caused has a strong therapeutic effect.
10. Effects on smooth muscle
Because there are many chemical components in purslane, there are obvious differences in the effect of uterine smooth muscle. For example, the inorganic potassium salt has an excitatory effect on animal uterine smooth muscle, while its organic component has an inhibitory effect. Potassium salts are mainly found in stems and organic components are mainly found in leaves.
