Second, relieve premenstrual syndrome When we find that the usually lively, lovely and gentle female companion suddenly becomes depressed and grumpy, the most intuitive guess of ordinary people may be "Ah! She must be the one who came. " Most women spend almost half their lives with "good friends" for five to ten days every month. However, because the female body starts about two to three days before menstruation, the prostaglandin concentration in the body will increase due to hormonal changes, and the endometrium will fall off and bleed during menstrual cramps. gla contained in evening primrose oil can inhibit the increase of prostaglandin concentration that causes inflammation. There was once a clinical experiment in which evening primrose oil was used as a drug to treat severe breast pain caused by premenstrual syndrome. The results showed that the effect of evening primrose oil was similar to that of traditional oral hormone preparation in treating breast pain (P.M. genolet et al., Diagnosis and treatment of breast pain, Red Med Sruisse Romande,1995; 1 15(5): 385-390)。 Another problem faced by women is osteoporosis, so how to reduce the loss of calcium has become an important topic. According to the experiment on mice, it was found that the urine calcium content of a group of mice fed with evening primrose oil was obviously lower, and it was more meaningful for hypercalcemia mice to prevent calcium loss (i.tulloch et al., Evening primrose oil reduced urine calcium excretion of normal and hypercalcemia rats, 1994 22(4) 227-230). This experiment also supports that taking evening primrose oil can reduce calcium loss and prevent osteoporosis. Because there are many kinds of evening primrose oil, which is helpful to women's physiological health care, evening primrose oil should be the first choice for female friends in the health food market.
Third, it can reduce the incidence of thrombosis. Evening primrose oil, like deep-sea fish oil, is an extremely polyunsaturated essential fatty acid, which will replace the inflammatory endogenous factors produced by arachidonic acid during metabolism in the body, such as prostaglandin, leukotriene and coagulation that causes coagulation reaction. Therefore, evening primrose oil not only has anti-inflammatory effect, but also has the effects of reducing coagulation reaction and preventing thrombosis (e.j. steven et al., release of prostacyclin in experimental diabetes: the effect of evening primrose oil, prostaglandin leukocyte essence fatty acid,1993 sep; 49(3): 699-70 1)。
In addition, biochemist Van Kloc-0/995 published an article in the Journal of Arterial Biomedicine, pointing out that gla can reduce the proliferation of giant cells and smooth muscle cells, and at the same time reduce the incidence of arteriosclerosis.
Evening primrose oil not only has preventive and therapeutic effects on common cardiovascular diseases of the elderly, but also is very useful for diabetes, another disease of the elderly. Neuroatrophy is a common side effect of diabetic patients. Scientists have also found that evening primrose oil can protect nerve cells and reduce the incidence of neuropathy (N.E. Cameron et al., Br.J. Pharmacol,1993; 109(4) 972-979; C.d. dines et al., European Journal of Pharmacology,1995 aug; 28 1(3): 303-309)。 Grant, a British biochemist, fed a group of pregnant diabetic mice with evening primrose oil, and found that compared with mice without evening primrose oil, the weight and health status of the mice born were normal. They also found that evening primrose oil can reduce the incidence of diabetes. Although this is not an experiment aimed at people, it is actually a good choice to use evening primrose oil as a chronic disease maintenance!
Fourthly, when cancer is mentioned in the study of anti-cancer effect, most people may classify it as a big killer to end human life, and treatment afterwards is always less meaningful than prevention beforehand. Therefore, no matter what kind of health food, most of them will "find a way" and "fight cancer". In fact, the anticancer effect of evening primrose oil only stays in the research stage with mice as samples. The anti-cancer principle is that evening primrose oil can "reduce" the lipid peroxidation of mouse adipocytes, because peroxidation will produce free radicals, denature cells and cause cancer lesions (S. Kokura et al., the efficiency of hyperthermia and heterogeneous fatty acids on experimental cancer; Cancer research,1997 jun; 57( 1 1):2200-2202)。
Therefore, evening primrose oil is considered to have anti-tumor effect. In addition, scientists also found that gla can hinder the fusion reaction between normal vascular cells and tumor endothelial cells, thus slowing down the development of tumor lesions (w.g. jiang et al., gla regulates gap junction communication of endothelial cells and its interaction with tumor cells. , prostaglandin leukocyte essential fatty acid,1997 apr; 56(4): 307-3 16)。
