What is the refining and storage of Evening Primrose Oil?
Evening primrose is mainly produced in northeast and northwest China. At present, it is planted in Heilongjiang, Inner Mongolia, Shanxi, Shaanxi, Jilin and other places. Due to the different varieties of raw materials, producing areas and harvest time, the product quality is different. Evening primrose seeds generally contain 15%~26% oil, and the content of γ -linolenic acid in oil is 9%~13%. However, because evening primrose oil contains more than 90% unsaturated fatty acids, its special fatty acid composition leads to poor stability and easy oxidative rancidity. Therefore, in the process of processing and storage, we should minimize the processing procedures, reduce the chance of contact with air, and avoid the influence of high temperature, especially in the softening and pressing procedures, solvent evaporation and stripping procedures in the leaching process, alkali refining, decoloration and deodorization procedures in the refining process, and we must strictly control the operating conditions.
Under normal circumstances, the output of evening primrose oil is determined by order, so it is directly packaged after processing and generally not stored in large quantities. Refined evening primrose oil liquid is usually packed in 180kg iron drums, which are filled with helium and sealed. In order to prevent oil from oxidation and rancidity during storage and transportation, it is required to store it at low temperature and avoid light as much as possible.
What are the effects and functions of Evening Primrose Oil?
Evening primrose oil can blend the oils of base oil and essential oil, and has multiple therapeutic and whitening functions. It can be taken orally as a capsule to treat cardiovascular diseases. When used in aromatherapy, it can blend lotion and cream, improve eczema and psoriasis, help wound healing, nail development, and solve hair problems. Generally, it is used at a dose of 10%. Evening primrose oil also has the effects of reducing blood fat, anti atherosclerosis, weight loss, anti fatty liver, anti arrhythmia, anti inflammation, etc.
How should we use evening primrose oil?
Adult women with menstrual, premenstrual or menopausal discomfort need to supplement evening primrose oil.
Patients with dermatitis, rheumatoid arthritis and multiple sclerosis can appropriately supplement evening primrose oil.
Ladies with poor skin condition should be properly supplemented with evening primrose oil.
Alcoholics will lack γ -linolenic acid, and many people in western countries will lack γ -linolenic acid because of age, blood sugar intolerance, high fat intake and other diseases.
People who are deficient can get enough γ -linolenic acid by supplementing evening primrose oil, red currant seed oil or borage oil.
Although, in people's long-term use process and clinical verification, evening primrose oil has not seen obvious side effects.
However,evening primrose oil liquid is also something that needs attention in the process of use.
For example, it is not suitable for minors to take evening primrose oil, and women with uterine fibroids should follow the doctor's instructions. It is not suitable for women to take it between menstrual periods, and women with more menstrual periods should reduce it.
