Evening primrose [scientific name]
"Alias" cordate telosma, wild sesame, wild sesame
Evening primrose, also known as sesame and Pennisetum, is a biennial plants of Salicaceae, which is commonly found in sunny slopes, wasteland and gravel fields along the banks of rivers in mountainous areas. When analyzing the oil of evening primrose seeds, the Institute of Forestry and Soil of China Academy of Sciences found that the reason why evening primrose seeds have such magical medical effects is that it contains a substance called r- linolenic acid. This is an unsaturated fatty acid, which cannot be "made" by itself in the human body. It must be supplemented by foreign food and is easily absorbed by the human body. It has obvious antithrombotic and hypolipidemic activities, and can regulate the physiological functions of human body, thus greatly enhancing people's resistance to diseases.
The study also found that evening primrose seed oil has a wide range of uses. It is not only a good clinical drug, but also an ideal nutritional supplement. Can be mixed with sunflower oil, corn oil, willow oil, etc. Manufacturing advanced nutritional body oil, baby nutrition agent, "artificial fish oil" and so on. In addition, it can also be used to prepare cosmetic ointment, grease, emulsion, etc. It has the effect of beautifying skin and delaying skin aging, so it enjoys another name of "beauty oil".
Evening primrose oil, also known as evening primrose or cordate telosma, is a plant that produces beautiful yellow flowers at night. Linoleic acid can be extracted from the mature seeds of evening primrose. Linoleic acid is an important substance for human body to produce prostaglandin, which can help human body to produce hormone-like substances and regulate hormone balance. Linseed oleic acid can inhibit the inflammation caused by endometrial shedding and bleeding during menstrual cramps, and help alleviate the discomfort of premenstrual syndrome and menopausal symptoms. In addition, evening primrose oil also helps to reduce the loss of calcium.
What's more exciting is that the pharmacological test proves that the evening primrose seed oil has no carcinogenic and teratogenic side effects on human body and is very safe. At present, many foreign medical scientists are stepping up the research on the chemical, pharmacological and clinical application of evening primrose seed oil, and Chinese medical workers are also studying the cultivation and comprehensive utilization of evening primrose. With the progress and development of modern medical science and technology, evening primrose, a wild plant, will play an increasingly important role in human health.
Evening primrose of Salicaceae
Native to North America, it was introduced to China through Europe in the17th century and escaped into the wild. Evening primrose is cold-tolerant, drought-tolerant, barren-tolerant, light-loving and water-repellent, and it needs some low-temperature stimulation to pull out vines and blossom.
Biennial plants height100-140 cm; The annual height is 60-90cm. Basal leaves are rosette-shaped, stem leaves alternate, lower leaves are long and narrow, and upper leaves are short. The stems are erect and branched. The root before bolting is fleshy and white, and the taproot is lignified after bolting. Flowers yellow, 4-5 cm in diameter. Petals are heart-shaped. The flowering period is June-65438+1October, and the fruit maturity is August-165438+1October. Direct seeding or seedling transplanting can be carried out. The direct seeding seeds should be treated at low temperature in advance, and then sown. The sowing amount is 0.2g/m2, and after sowing, the soil is about 0.5cm Evening primrose flowers bloom at night, with pleasant fragrance, which is suitable for decorating night scenes. Together with other greening materials, it can be used in gardens, courtyards, flower beds and roadside greening.
Evening primrose, commonly known as evening primrose, is a biennial herb.
Evening primrose mainly grows on the sand beside the river, but it is also found in mountains and deserts. Evening primrose blooms slowly at night and withers at dawn. This is a plant that only opens to the moon. Indians were the first people to use evening primrose for therapeutic purposes. They use evening primrose to treat trauma, dermatitis and other diseases. Evening primrose was brought to Europe in the19th century. Because of its curative effect on many diseases, evening primrose soon gained the reputation of a panacea.
It is an oil plant with the same origin of medicine and food, and has the effects of lowering blood pressure, reducing blood fat, losing weight and resisting cancer. Characteristics: The plant height is 80- 130 cm, the inflorescence is infinite, the flowering period is July, the fruit is quadrangular, there are many seeds, and the mature harvest period is generally in the middle of September. This variety is barren-tolerant, drought-tolerant, close planting-tolerant, free of pests and diseases, easy to cultivate, simple in management and lax in soil requirements, and can be planted in soil below pH8. It is advisable to land on the hill to avoid depression, and sow after the land is harrowed.
I have evening primrose oil for export and take it orally. I used it myself, and the effect is very good. . . Many relatives and friends at home are using it. My premenstrual side effects are gone and my skin is getting better. . . .
Evening primrose oil is highly valued in Europe and the United States in promoting health.
Evening primrose oil, called evening primrose oil in English, is an oil extracted from evening primrose seeds. This kind of grease is unusual.
Reduce total cholesterol synthesis
According to the research of scholars all over the world, it contains a rare polyunsaturated fatty acid-γ linolenic acid (GLA for short), which has a unique role in promoting human health. This is Y-evening primrose oil, which has received more attention recently.
It turns out that Y- linolenic acid is an essential fatty acid for human body, but it can't be made by itself, and it has a good regulating effect on human physiological function. Especially today, medical research reports in many countries point out that γ -linolenic acid has the function of lowering total cholesterol.
This is mainly because γ -linolenic acid is a polyunsaturated fatty acid, which increases the water solubility of total cholesterol and makes it easily metabolized by enzymes. At the same time, it can remove triglycerides from blood and reduce the synthesis of endogenous total cholesterol.
In addition, Y- linolenic acid can also increase high-density lipoprotein, so it can also inhibit the uptake and accumulation of low-density lipoprotein cholesterol in cells, and even eliminate the accumulated cholesterol in cells. Invisible to reduce triglycerides, cholesterol, B- lipoprotein has a significant effect.
Inhibition of atherosclerosis
In terms of thrombosis, γ -linolenic acid can also reduce the risk of thrombotic cardiovascular and cerebrovascular diseases, inhibit the formation of atherosclerosis, protect ischemic myocardium, reduce necrotic area and maintain the normal function of platelets.
Because γ -linolenic acid also has obvious anti-lipid peroxidation effect, it is of great significance to protect human health and delay human aging.
In recent years, the clinical research on γ -linolenic acid is very active in the medical field, and it is also found that γ -linolenic acid has a good improvement effect on obesity, schizophrenia, menstrual syndrome, periodic breast pain and various inflammations (rheumatoid arthritis, ulcerative colitis, nephritis, etc.). ), indicating that γ -linolenic acid has a broader medicinal prospect.
Generally speaking, we usually ingest linoleic acid from food. Linoleic acid is transformed into γ -linolenic acid through the action of enzymes and a series of biosynthesis in the body, maintaining normal functions. When the human body ingests excessive saturated fatty acids or other metabolic disorders, it will affect the conversion of linoleic acid to γ -linolenic acid, thus affecting the normal operation of functions and leading to various diseases.
Therefore, if γ -linolenic acid can be supplemented in time, it can promote the normal metabolism of body functions and thus reduce the occurrence of diseases.
Because the fatty acids in evening primrose oil are mainly unsaturated fatty acids, which are easily oxidized and denatured in the air, today's advanced pharmaceutical companies make evening primrose oil into soft capsules to prevent evening primrose oil from being oxidized and facilitate people to take it.
