Objective Evening primrose oil is the most important nutritional medicine discovered in this century. Seeds contain 20-30% oil, of which 70% is linoleic acid and 8-9% is γ -linolenic acid necessary for human body. Evening primrose oil can treat many diseases, regulate lipid substances in blood, and has remarkable curative effect on coronary artery infarction, atherosclerosis and cerebral thrombosis caused by high cholesterol and hyperlipidemia. It can also treat various sclerosis, diabetes, obesity, rheumatoid arthritis and schizophrenia. It is also found in the laboratory that it can inhibit the growth of cancer cells. Clinically, evening primrose oil can prevent cardiovascular obstruction and reduce cholesterol, thus preparing specific drugs for preventing and treating cardiovascular diseases. Evening primrose is also a good material for arranging flower beds. The flowers of evening primrose can extract the essence.
Evening primrose oil contains a large amount of essential fatty acid-γ -linolenic acid (GLA), and its activity is ten times higher than that of linolenic acid. The earliest diseases treated by evening primrose are multiple sclerosis, atopic dermatitis and rheumatoid arthritis.
Evening primrose originated in America, and its medicinal value was discovered by Indians hundreds of years ago. Soak the whole evening primrose in warm water, make a lake plaster to treat bruises, and apply it on the skin surface to treat skin trauma and dermatitis.
It was not until the18th century that the seeds were brought to England by ships carrying cotton. It was also at this time that Europe began to develop the efficacy of evening primrose, and many scientists and doctors devoted themselves to the research of evening primrose and used it to treat multiple sclerosis, atopic dermatitis and rheumatoid arthritis.
Two magical ingredients of evening primrose
Evening primrose contains a lot of essential fatty acids and gla: γ -linolenic acid. If you want to know why evening primrose has such important medical and health care value, you must understand the influence of these two components on human body.
The so-called "essential fatty acids" are substances that are very important to the human body, but cannot be synthesized by themselves and must be ingested from the outside. Its functions in the body are as follows:
Provide energy
Maintain body temperature
Protect tissues and organs
Most importantly, it is an indispensable substance for cells and tissues in the body, and it is also a substance for the human body to synthesize important prostaglandins and hormones. It is conceivable that without essential fatty acids, the human body will face:
Hair falls off and the wound is not easy to heal.
D seriously affects reproductive function.
Immune function is reduced, and the probability of being infected by viruses and bacteria is greatly increased.
Generally speaking, people will naturally ingest "essential fatty acids" from foods such as milk and vegetable oil. However, in recent years, due to the excessive intake of "high cholesterol, high fat and high sugar" in modern people's dietary sources and habits, these foods are not only the source of malnutrition, but also hinder the body's absorption of normal "essential fatty acids". This is an example where "overnutrition" equals "malnutrition".
Evening primrose is mainly composed of 70% linolenic acid and 9% γ -linolenic acid, which are two kinds of "essential fatty acids", which also explains why evening primrose is so important to human body.
prostaglandin
Among the components of evening primrose, another component that is listed as the focus of medical research is prostaglandin. 1930, a Swiss scientist discovered this substance in semen and named it "prostaglandin". Later, it was found that prostaglandin is ubiquitous in human body, and there are many different combinations, which play a synergistic role in different human bodies.
For example, we can know what magical influence the evening primrose has exerted here: the medical profession likes to use steroids as anti-inflammatory and anti-allergic formulas, and steroids can really achieve this effect quickly, but steroids not only have great side effects, but also inhibit "inflammatory prostaglandin" and "inflammatory prostaglandin" on the human body; Evening primrose is characterized by synthesizing and increasing "anti-inflammatory prostaglandin", but inhibiting "inflammatory prostaglandin". This unique biological activity makes evening primrose a more "intelligent" formula countermeasure and greatly reduces the possibility of side effects. This explains why evening primrose may be a great blessing for allergic patients.
PMS premenstrual syndrome and evening primrose
Evening primrose is an important source of endocrine substances such as hormones, prostaglandins and hormones. Supplementing evening primrose also indirectly maintains the balance of endocrine substances, so another syndrome that most benefits women is premenstrual syndrome.
Simply put, most patients with PMS lack essential fatty acids (EFAs) required by prostaglandin, while estrogen (estrogen) and prolactin (prolactin) are on the high side, thus causing many physiological and psychological obstacles and discomforts. The most common standard symptoms are:
Physiological symptoms include chest swelling, chest pain, headache, heavy head and fever.
Psychologically, there are drowsiness (drowsiness and fatigue), overeating, impatience, depression and easy emotional loss of control.
Among women aged 65-438 +05-50, more than 50% are patients with PMS. Evening primrose supplements essential fatty acids and synthesizes EFAs to balance body secretion. This theoretical basis supports the experimental models of many research units in Europe and America. The clinical researcher of PMS in Massachusetts, USA, once published that "the method of improving PMS through nutrition has a 70% success rate". Under the control of several groups of experiments, the statistical result of * * * is: take 1-2 0.5g evening primrose oil every day.
Eczema and atopic dermatitis
We often say that people with atopic dermatitis are "physical" problems. Usually, patients have different degrees of skin problems, which are easy to dry and itch, and there are often unexplained allergies. In the harsh or extreme climate change environment, the skin can not provide the necessary protection, and it also makes patients itch and ache.
A common reason for the so-called "poor constitution" is that although patients have ingested enough essential fatty acids, they still cannot synthesize γ _ GLA and other essential substances because they lack sufficient transformation mechanism in their bodies. At this time, it is an excellent nutritional supplement scheme to supplement GLA directly with evening primrose.
In the experimental study, it is found that evening primrose has a good effect whether it is taken orally or absorbed by the skin. However, in the treatment of eczema, evening primrose oil must be applied to a healthy part to be absorbed, and if it is applied to the affected part, it will be counterproductive.
Evening primrose and skin
Lack of essential fatty acids can lead to skin moisture loss, dryness and aging. German researchers used an instrument that can measure skin smoothness to study the effect of evening primrose oil on skin. The results show that evening primrose oil can make the skin of the subjects smoother and more energetic, whether orally taken or directly applied.
This experiment encourages researchers to conduct more in-depth research and testing on nails, eyes, hair and other body surfaces. The results show that evening primrose oil has a wide range of uses, which makes many well-known cosmeceuticals use evening primrose oil as an important high-grade component of skin care products.
Other relevant months? I don't know.
Some cases of hyperactive children are caused by lack of essential fatty acids. For this kind of cases, the HACSG diet designed by Ben Feingold Research Center in the United States provides a recommended diet prescription including evening primrose, which has achieved good results.
According to the research of Glasgow Royal Hospital, the compound capsule of evening primrose oil and deep sea fish oil can control and improve the condition of most patients, and about 60% of them can be maintained without continuous taking. The role of deep-sea fish oil here is an important source of vitamin E supply, but the above-mentioned clinical experiments have not confirmed the reason, and it is inferred that it is related to endocrine disorders. GLA and EFAs provided by evening primrose oil can balance this imbalance.
In China's Chinese medical classics, evening primrose is made into herbal medicine, which is used to treat gastrointestinal problems, asthma, cough, wound healing and female diseases, because the secret of relieving female physiological pain and discomfort is that it is rich in γ -linolenic acid and linolenic acid, which can dilate blood vessels, promote blood circulation and regulate hormones, relieve menstrual discomfort and even improve menopausal disorders.
Practical small formula of evening primrose oil
1. Mix evening primrose oil with other base oils to prepare essential oils (rose, geranium, jasmine, etc. ), massage the lower abdomen and skin, can relieve menstrual pain, swelling of the lower abdomen before menstruation and prevent dry skin.
2. Evening primrose oil mixed with chamomile and patchouli can be used for urticaria and atopic dermatitis, which can improve allergy and relieve itching.
3. Mix evening primrose oil with birch and ginger essential oil and massage joints to prevent arthritis and joint stiffness.
Oral evening primrose oil under the guidance of professionals can improve premenstrual syndrome and eczema. It is suggested to use it in combination with antioxidant sources with high vitamin E content such as deep-sea fish oil and cranberry seed oil.

★ About the magical evening primrose oil:
Evening primrose, also known as evening primrose, is named after it blooms in the evening and withers at dawn. Evening primrose oil is obtained from evening primrose seeds and is rich in GLA(γ- linolenic acid). γ -linolenic acid is an essential fatty acid, which cannot be synthesized by itself in human body and must be taken in from outside. It is "processed" into a hormone-like substance (prostaglandin E 1) in human body.
★ Physiological functions of γ -linolenic acid:
◇ Adjust endocrine balance and improve premenstrual syndrome, such as relieving breast pain, menstrual disorder, abdominal pain, backache, etc.
Improve menopausal syndrome, such as emotional anxiety, irritability, insomnia, dizziness, hyperhidrosis, etc.
Improve wrinkles, pigmentation, yellow and black skin, premature aging and obesity, and prevent allergic dermatitis.
◇ Reduce serum cholesterol and triglyceride levels, inhibit platelet aggregation in vivo, and prevent thrombosis.
◇ dilate blood vessels and lower blood pressure.
Inhibit rheumatoid arthritis, etc.
◇ Strong dry hangover.
