pharmacological action

1. Antibacterial Action Qu reported that the ethanol extract of Portulaca oleracea had obvious inhibitory effect on Shigella and Parashigella flexneri. The decoction has inhibitory effects on Shigella, Sonnerella, Shigella flexneri and Shigella flexneri, but Shigella flexneri can produce obvious drug resistance after repeated passages in purslane broth. Alcohol extract or decoction also has inhibitory effect on Escherichia coli, typhoid Bacillus and Staphylococcus aureus. It also has different degrees of inhibition on some pathogenic fungi, such as tinea pedis. No inhibitory effect on mycobacterium tuberculosis; For mice infected by E.coli injected intraperitoneally, ethanol extract or decoction of residue after ethanol extraction is ineffective. 1992 Ma reported the bacteriostatic effect of wild purslane sold in Shenzhen vegetable market on many common food contamination bacteria. The results showed that Portulaca oleracea had a strong inhibitory effect on many common food contamination bacteria. Even if diluted to the concentration of 12.5%, it still has certain antibacterial effect. Especially for many bacteria, such as Escherichia coli, Salmonella, Proteus, Shigella, Staphylococcus aureus, Bacillus subtilis, Bacillus cereus and so on. , has a strong antibacterial effect, but does not inhibit Garcinia cambogia, and its inhibitory effect on mycobacteria is not obvious. Portulaca oleracea can also inhibit some molds, such as Mucor racemosus, Gibberella, Alternaria and Aspergillus flavus. But it has no bacteriostatic effect on rhizopus nigricans, Trichoderma viride and Aspergillus Niger, and has no bacteriostatic effect on yeast.

2. Effect on Smooth Muscle 1985 Qu reported that Portulaca oleracea extract (prepared by decocting in water and extracting with alcohol to remove precipitate) and its crystallized potassium chloride have obvious exciting effects on isolated uterus of guinea pigs, rats, rabbits and in situ uterus of dogs. Portulaca oleracea injection 2ml (equivalent to 5- 10g) is stronger than ergonovine 0.2mg and weaker than pituitrin 10g. And 4-6 ml is similar to pituitrin 10 unit. Potassium chloride crystal isolated from Portulaca oleracea L. has obvious contractile effect on isolated ileum of rats, and its strength is equivalent to prostaglandin E 1, 200 ug and neostigmine 0.25mg, while 0.2ml of 20% decoction has inhibitory effect on isolated small intestine of guinea pigs. Since then, foreign scholars, such as SunbhanichM, have studied the effects of fruit juice and boiling water extracts from fresh purslane plants on the peristalsis and contraction of isolated atrium and trachea in guinea pigs. The results showed that both water extract and boiling water extract could enhance the contraction tension, contraction amplitude and contraction frequency of isolated ileum. This effect is similar to acetylcholine and dose-dependent. But the increase of contraction tension and peristalsis can be slightly blocked by atropine. The two types of preparations showed dose-dependent effects on myocardial contractility and contraction rate, as well as relaxing effects on isolated tracheal strips. These effects are similar to those produced by isoproterenol and can be completely blocked by propranolol (2. 1x 10(-5)mol/L). The effects of Portulaca oleracea on isolated ileum and atrium of guinea pigs show that it can be used as relaxant and cardiotonic respectively, and its bronchodilatory effect can be used to treat bronchial asthma.

3. Effect on skeletal muscle:

OkwuasabaF = 1987。 It is reported that the water extract of Portulaca oleracea has the unique characteristics of relaxing skeletal muscle in vitro and in vivo. Local use of this water extract is effective for skeletal muscle rigidity caused by spinal cord injury. The pharmacological activities of various extracts of Portulaca oleracea were further studied and compared with water extracts. The results showed that various extracts of Portulaca oleracea L. [methanol (MEE), diethyl ether (DEE) and dialysis (DIF) extracts] had similar inhibitory effects on rat diaphragm (ms and NS) and rectus abdominis muscle as water extract (AEE).

These three extracts all have:

3. 1. A biphasic reaction consisting of an initial increase in convulsive tension followed by a long-term sustained inhibition;

3.2. Significantly reduce the twitch/stiffness ratio of contracture caused by K+ and caffeine;

3.3. Attenuate the contraction of rectus abdominis caused by agonist nicotine. Non-dialysis (NDF) extractors showed slight muscle relaxation, but did not reduce contracture caused by agonist nicotine. The mechanism of action can be inferred as follows: purslane water extract and organic solvent extract interfere with various calcium pools to produce muscle relaxation, which is related to the excitation-contraction coupling of starting calcium pools and intracellular calcium pools. Caffeine-induced contraction is partly due to the mobilization of sarcoplasmic reticulum (SR) calcium pool, which can partly explain the observed weakening of caffeine contraction by various Portulaca oleracea extracts. Other effects of these extracts, such as inhibiting convulsion (MS) and tension, can be explained by similar mechanisms. The order of IC50 intensity of these extracts is dif≥mee >；; Dee. Because the distribution coefficient of methanol is lower than that of ether, it may be that the methanol extract contains more active components of purslane muscle relaxation. According to the obvious effect of DIF and the fact that 100% acetonitrile extracted by high pressure liquid chromatography has no relaxation effect on skeletal muscle, it can be considered that the effective components of purslane may contain polar components.

4. Effect on uterus: Li Shourou = 1979. It is reported that purslane has two opposite effects on animal uterus. One is excitation, which is potassium chloride distributed in purslane; One is inhibition, which is an organic component in purslane. Potassium salt mainly exists in stems, and organic components mainly exist in leaves.

5. Effect on cardiovascular system: Lanzhou Medical College reported that 0.2ml of 20% water decoction had inhibitory effect on isolated frog heart. Intravenous injection of 3 ml in each anesthetized dog has no obvious effect on respiration, blood pressure and heartbeat.

6. Promote ulcer healing: According to the report of the National Collection of Chinese Herbal Medicine, this product is rich in vitamin A substances, so it can promote the physiological function of epithelial cells to become normal.

7. Other effects: StefanovZH et al reported that the water-soluble and fat-soluble extracts of Portulaca oleracea can prolong the life span of rats and rabbits with severe diabetes induced by alloxan, but it does not affect the blood sugar level, suggesting that Portulaca oleracea extract can improve the lipid metabolism disorder.

Excerpt from this passage edited by the National Collection of Chinese Herbal Medicine | Back to the Top The fairy tale of Portulaca oleracea and Yi is the most famous shooter in ancient myths and legends in China. It is said that Yi comes from a poor family and is a good archer. No matter he is tall, far, moving or small, he can always hit the target.

Yao's time will come out in ten days. Burning crops kills plants, but people have nothing to eat. Yu Ya Yu Ya, tooth cutting, nine babies, gale, altar sealing (Xixi) and snake repairing are all harmful. Yao is the man who killed nine babies in the water god, paid a strong wind in Qingshan, shot up and down for ten days, killed the snake in Dongting, and sealed the bird in Sanglin (and escaped). When everyone tasted it, Yao thought he was the son of heaven. So the world is wide and narrow, dangerous and easy, far and near, and there is a way.

Under Yao's command, Yi shot down 10 suns and six terrible beasts harmful to human beings. From then on, whether it is wide or narrow, whether it is steep or easy, whether it is far or near, it is unimpeded.

Yi Jianlian can only shoot nine times in 10 days, and one day he survived under purslane. In order to repay Portulaca oleracea for saving his life, he knew that no matter how hot the weather was, the sun could not kill Portulaca oleracea.

Dermatitis of paederus fuscipes

(paederus fuscipes dermatitis)

Paederia venosus dermatitis is a common skin disease in midsummer, and the high incidence season is from June to September every year. Paederus venosus often lives in wet grasslands and under rotten rocks. It lurks during the day and comes out at night. It likes flying at high altitude, has strong phototaxis and can secrete a strong acidic venom, which can cause inflammatory reaction after skin contact.

What are the clinical characteristics of dermatitis caused by saphenous wing?

1. The incidence of paederus venosus dermatitis has obvious seasonality, with the highest incidence from June to September, especially in the sultry weather around rainy days.

Skin lesions are more common than those found after waking up in the morning. Skin lesions are mainly exposed parts of face, neck, chest, back and limbs, showing linear, patchy or punctate edema and erythema, on which densely arranged yellow-white blisters or pustules are distributed. Linear injuries are as different and irregular as scratches on bamboo sticks or nails. Patchy skin lesions are similar to skin burns, and the length of skin lesions varies, generally about 2 ~ 5 cm long, and the longest can reach more than 10cm.

3. The lesion of the affected area is burning and stinging, and severe cases may be accompanied by nausea, vomiting, aversion to cold, fever and other systemic symptoms. The course of the disease is usually about one week, and the skin lesions are dry, scabbed and exfoliated. Pigment spots can be temporarily left in the local area.

Portulaca oleracea (fresh is better) can be used as a single prescription and pounded in the affected areas twice a day.
