Benefits Of Evening Primrose Oil
1. Helps Treat Acne
Evening primrose oil contains gamma-linolenic acid (GLA) that helps improve skin moisture and shows anti-aging effects by reducing water loss through skin. This omega-6 fatty acid has anti-inflammatory properties and may also improve skin barrier function (1) (2). A study suggests that a combination of omega-3, 6, and gamma-linolenic acid has the highest potential to minimize inflammatory skin conditions like acne, psoriasisi XA non-contagious autoimmune disorder where skin cells accumulate and develop into scales and dry, itchy areas. , and atopic dermatitisi XAn inflammatory, itchy skin condition usually manifests as rashes on the arms and behind the knees. (2).
Evening primrose oil was also found to treat xerotic cheilitis (chapping of lips) in people with acne who were being treated with oral isotretinoin (a retinoid) (1). However, more studies are needed in this regard.
2. May Ease Atopic Dermatitis
Evening primrose oil contains 72% linoleic acid and 10% gamma-linolenic acid. Its oral supplementation may reduce eczema or atopic dermatitis (red and itchy skin) (3). A review published in Annals of Dermatology also backs this claim (4). However, not all studies have shown similar results. Hence, further trials are needed.
3. May Relieve PMS Symptoms
Taking two capsules (500 mg) of evening primrose oil twice a day for six weeks was found to decrease the intensity of hot flashes (5). Similarly, a review published in the Journal of Menopausal Medicine found that taking 1000 mg capsules twice a day may reduce the frequency and severity of night sweats (6). The gamma-linolenic acid in evening primrose oil may also treat depression, irritability, and breast pain and tenderness associated with premenstrual syndrome (7). Besides, taking a supplement containing vitamin E, vitamin B6, and evening primrose oil may also relieve PMS symptoms (8).
4. May Improve Heart Health
Supplementing evening primrose oil through diet was shown to decrease vascular thrombogenesis (blockage in blood vessels) in rabbits (9). Besides, the omega-6 fatty acids in evening primrose oil are also known to reduce the risk of cardiovascular disease. The oil was found to improve cardiac recovery in hypercholesterolemic (high blood cholesterol levels) rats (10). However, more human studies are warranted to understand this benefit of evening primrose oil.
5. May Minimize Nerve Pain
Nerve pain is commonly associated with diabetic neuropathy. Ingesting 360 mg of gamma-linolenic acid may help prevent and treat diabetic polyneuropathy (11). The omega-6 fatty acid and linolenic acid in evening primrose oil may also treat nerve disturbances (12). Besides, linolenic acid deficiency may cause weakness, numbness, blurred vision, and inability to walk (13).
6. May Reduce Osteoporosis Risk
Experts predict that osteoporosis-related fractures may increase health care expenditure by 25.3 billion dollars by 2025 (14). A diet rich in polyunsaturated fats (PUFAs) may help reduce the risk of osteoporosis in women post menopause who are on hormonal therapy (15). Evening primrose oil is rich in these fats and linolenic acid, and was found to improve bone mineral density among older people (16). Besides, a combination of evening primrose, fish oil, and calcium may improve bone density and decrease bone loss (17). However, more studies are warranted to understand the benefit of evening primrose oil.
7. May Reduce Rheumatoid Arthritis Symptoms
Rheumatoid arthritis (RA) is an autoimmune and inflammatory disease that affects the joints. A study conducted by Australian Catholic University, Australia, found that gamma-linolenic acid from evening primrose oil may help relieve symptoms of rheumatoid arthritis (18). Taking 540 mg/day of gamma-linolenic acid through a diet for six months was found to improve the condition (19). Besides, the anti-inflammatory properties of evening primrose oil may help reduce the inflammation associated with rheumatoid arthritis (20).
8. Helps With Hair Growth
Evening primrose contains arachidonic acid (omega-6 polyunsaturated fatty acid), which has been found effective in promoting hair growth (21), (22). This fatty acid was shown to enhance the proliferation of follicles and their survival. However, more studies are needed to understand the benefit of evening primrose oil.
In addition, evening primrose oil can improve fatigue and quality of life in patients with multiple sclerosis (inflammatory disease of the central nervous system) (23). Also, taking a combination of evening primrose oil (3000 mg) and vitamin E (1200 IU) for six months may help reduce cyclic mastalgia (breast pain) (24).
Anecdotal evidence suggests that it may also help with skin diseases like rosacea. The vitamin E in evening primrose oil may also help boost the immune system and aid in wound healing. However, more studies are warranted to support these claims.
