Evening primrose oil shows promise

Based on 16 Researches

Biagi PL, Bordoni A, Masi M, Ricci G, Fanelli C, et al. A long-term study on the use of evening primrose oil (Efamol) in atopic children. Drugs Exp Clin Res. 1988;14:285.

We explored the effects of evening primrose oil on children's atopic eczema over a 20-week period. Initially, we observed that kids who took this oil showed significant improvement in their skin conditions after just four weeks. Remarkably, those benefits continued throughout the entire treatment duration. Along with these clinical improvements, we also noted changes in the fatty acid composition in the children's blood cells. Despite these positive findings, it's worth noting that opinions about the effectiveness of evening primrose oil vary among researchers, making the overall consensus somewhat unclear.

Significant reduction

I have suffered from mild eczema for over 40 years. Despite trying various diets, topical creams, and allergy tests, nothing worked long-term. This supplement is the first thing that has significantly reduced my eczema by about 90-95%! I still get occasional breakouts, but they are shorter and milder. I take three pills daily, and the Solgar Evening Primrose Oil is gentle on my stomach—truly a life-changer!

Updated: Mar 2026

This study explored whether evening primrose oil (EPO) could replace non-steroidal anti-inflammatory drugs (NSAIDs) for people with rheumatoid arthritis (RA).

Over 12 months, we noticed that patients taking EPO showed notable subjective improvements and were able to reduce their NSAID intake.

However, a follow-up after three months of placebo indicated that while they felt better initially, their symptoms returned.

Importantly, EPO didn't change underlying disease progression, meaning it may not be a cure but can support symptom relief.

I drank about 10 pieces, and something didn't work for me. My chest ached a little and the lymph nodes began to ache under my armpits. I've put these capsules aside for now; perhaps I'll try again later.

Moderate benefits, mixed evidence

Possibly Effective

Based on 6 Researches

Cameron M, Gagnier JJ, Chrubasik S. Herbal therapy for treating rheumatoid arthritis. Cochrane Database Syst Rev. 2011. doi:10.1002/14651858.CD002948.pub2

We examined the latest insights into herbal therapies for rheumatoid arthritis, including evening primrose oil. Our analysis included 22 studies, revealing moderate evidence suggesting that gamma linolenic acid (GLA), found in evening primrose oil, may ease pain and disability related to RA.

However, while some benefits were noted, the evidence remains mixed and the risk of side effects should not be overlooked. More comprehensive studies are needed to firmly establish its effectiveness for RA treatment.

I have been using evening primrose oil for a long while, and I can only share positive experiences. At 52, I started taking it for hot flashes, and it certainly helped. Additionally, it provided relief for my knee problems associated with rheumatoid arthritis. It’s noted that gamma-linolenic acid can alleviate the chronic inflammation pain typical of rheumatoid arthritis, making this oil a valuable addition to my routine.

Helps! My doctor prescribed me to take Femikaps for mastopathy, two capsules twice daily for three months. It’s rather expensive; however, it has been effective. I sought a more affordable option and found this oil, which has a similar dosage. I took it for three months, and my breast pain ceased to exist. After nine months, there have been no new nodes, and I plan to repeat the course to maintain the results.

Breast Cancer details

Evening primrose oil shows promise

Based on 3 Researches

Pritchard GA, Jones DL, Mansel RE. Lipids in breast carcinogenesis. Br J Surg. 1989;76:1069.

We analyzed how different types of dietary fats might influence breast cancer growth. In our study, we used athymic mice with human breast cancer cells and supplemented their diets with evening primrose oil and fish oil, while others received olive oil or a standard diet without essential fatty acids.

We found that the tumors in the mice receiving evening primrose oil were significantly smaller compared to those on a standard diet — suggesting that increasing essential fatty acids could play a beneficial role in managing breast cancer.

In our exploration of treatment options for mastalgia, we focused on the effectiveness of evening primrose oil combined with vitamin E. Conducted at King George's Medical University, the study assessed 106 female patients suffering from breast pain.

We measured psychological status using the DASS-42 scale and pain using a visual analog scale. While topical NSAIDs showed a strong response rate, evening primrose oil and vitamin E had a notable effect in 6.98% of patients.

Overall, both treatments proved valuable, though we found no correlation between psychological conditions and pain severity.

Miraculous product! Evening primrose oil has a significant positive effect on the female body!

Since then, evening primrose oil has been my constant companion, helping me to restore a normal 28-day cycle, alleviate symptoms of premenstrual syndrome, and reduce pain during menstruation. My nails have improved, too, becoming stronger and glossier.

Sleep Apnea details

I began taking this with some doubt, but the results surpassed all expectations. One capsule at night is sufficient for me; I avoided morning doses due to hypotension. At night, I sleep deeply and wake up feeling rested. Crucially, the hot flushes have stopped, which had been troubling me before.

I feel the benefit from this product as it lowers inflammation related to my adenomyosis. I'm experiencing greater hormonal balance and even think it has improved my skin.

Evening primrose oil benefits heart health

Heart Disease details

Charnock JS. Gamma-linolenic acid provides additional protection against ventricular fibrillation in aged rats fed linoleic acid rich diets. Prostaglandins Leukot Essent Fatty Acids. 2000;62:129.

We examined how dietary supplements, specifically evening primrose oil (EPO), impact heart health in older rats under stress. Rats that received EPO showed a notable reduction in severe ventricular fibrillation compared to those fed sunflower seed oil without gamma-linolenic acid (GLA).

Interestingly, while borage oil, which contains more GLA, didn't provide any extra benefits, it indicates that GLA plays a crucial role. However, the findings primarily apply to aged rats, so further studies are necessary to determine the overall effectiveness in heart disease management in different populations.

We investigated how evening primrose oil affects cardiovascular health in rabbits fed a high-fat diet. Over six weeks, we found that it contributed to lower cholesterol levels and improved beneficial HDL-cholesterol. Additionally, the oil boosted prostacyclin synthesis, which plays a key role in keeping blood vessels healthy.

Our analysis showed that evening primrose oil reduced platelet adhesion and the size of arterial wall lesions. This suggests it may support better vascular health by enhancing the endothelium's ability to prevent blood clots.

Evening primrose oil is an essential source of polyunsaturated fatty acids, particularly Gamma Linolenic Acid (GLA). It helps alleviate symptoms of cardiovascular disease, normalises blood pressure, and improves heart function.

Evening primrose oil enriched with gamma linolenic acid and D/L-alpha tocopherol acetate attenuated carbon tetrachloride-induced hepatic injury model in male rats via TNF-α, IL-1β, and IL-6 pathway. Toxicol Mech Methods. 2024;34:469. doi:10.1080/15376516.2023.2301357

We investigated how evening primrose oil, enhanced with gamma-linolenic acid and D/L-alpha tocopherol, could protect against liver damage in a rat model. In this study, male rats were divided into four groups, including a control and treatment group.

We found that the evening primrose oil group showed improvements in liver health compared to those exposed to carbon tetrachloride, a harmful substance. While liver enzymes returned to safer levels and tissue damage was reduced, the oil’s effectiveness emphasizes its potential benefits for supporting liver health.

Indispensable for women's health, I use it in the complex treatment of endometriosis at a dosage of 1300 mg twice a day. Primrose contains gamma linolenic acid (GLA), which suppresses inflammatory and autoimmune processes. What have I noticed? Critical days have become quite regular, without pain or spasms. Hormones are balanced, with no bias towards oestrogen. It is suitable for women with painful menstrual cycles and to prevent oestrogen-dependent diseases. It reduces unpleasant symptoms, such as hot flashes, during the climacteric period.

Evening primrose oil reduces LDL cholesterol

Based on 3 Researches

Ishikawa T, Fujiyama Y, Igarashi O, Morino M, Tada N, et al. Effects of gammalinolenic acid on plasma lipoproteins and apolipoproteins. Atherosclerosis. 1989;75:95.

We examined the effects of evening primrose oil, high in gammalinolenic acid, on cholesterol levels in nineteen patients with high cholesterol. This study used a rigorous crossover design where participants received both the evening primrose oil and a placebo safflower oil over 16 weeks.

During the evening primrose oil treatment, we noticed a significant reduction in low-density lipoprotein (LDL) cholesterol levels and apolipoprotein B in patients without hypertriglyceridemia. These findings suggest that evening primrose oil can be beneficial for individuals struggling with high cholesterol.

Evening primrose oil shows mild benefits

Kaźmierska A, Bolesławska I, Polańska A, Dańczak-Pazdrowska A, Jagielski P, et al. Effect of Evening Primrose Oil Supplementation on Selected Parameters of Skin Condition in a Group of Patients Treated with Isotretinoin-A Randomized Double-Blind Trial. Nutrients. 2022;14. doi:10.3390/nu14142980

We investigated the role of evening primrose oil in improving skin conditions for acne patients undergoing isotretinoin therapy. In a controlled study, participants were monitored over nine months to assess changes in skin hydration, oiliness, and body weight.

While evening primrose oil helped boost skin hydration, it didn't significantly outperform isotretinoin alone in other areas like oiliness or weight loss. This suggests that evening primrose oil may provide some benefits, but it doesn't drastically change the overall treatment outcome for acne patients on isotretinoin.
