Evening primrose shows promise
The effect of oral evening primrose oil on menopausal hot flashes: a randomized clinical trial.
Indicates potential treatment benefits
We explored the effects of evening primrose oil on menopausal hot flashes in a 6-week clinical trial involving 56 women aged 45-59. Participants received either evening primrose or a placebo and reported their hot flash experiences using a specific questionnaire.

While both groups showed improvement, evening primrose oil notably reduced the severity of hot flashes compared to placebo. Specific improvements were also found in social interactions and sexuality for those taking evening primrose, making it a promising option for managing hot flash symptoms.

Evening primrose oil lacks efficacy
Evening Primrose Oil for Menopause Hot Flashes: Systematic Review and Meta-Analysis.
Low relevance for hot flash treatment
We explored the effectiveness of evening primrose oil (EPO) as a treatment for hot flashes in menopausal women. Following rigorous systematic reviews and randomized trials, we discovered that while EPO showed some reduction in hot flash severity after less than six months, it did not significantly improve the frequency or duration of these symptoms compared to a placebo. Some participants did report mild nausea and headache. Ultimately, the evidence remains inconclusive, leaving us hopeful for further studies on EPO's potential benefits.

Evening primrose oil shows limited benefit
A comparative study on the effect of "black cohosh" and "evening primrose oil" on menopausal hot flashes.
Low relevance for hot flash treatment
We looked into how evening primrose oil (EPO) affects hot flashes in postmenopausal women. In our study, 80 women were divided into two groups; one received EPO while the other took black cohosh over 8 weeks. Both groups reported reduced severity of hot flashes and improved quality of life. However, the black cohosh group saw a significant decrease in the number of hot flashes, while EPO did not show significant improvements. This suggests that while EPO may help alleviate symptoms, black cohosh appears to be more effective overall.

Negative side effects
DO NOT TAKE EVENING PRIMROSE IF YOU HAVE ESTROGEN DOMINANCE! It increases estrogen production. After a period of regulation with progesterone, I read a review stating it aids sleep and tried it. Unfortunately, it disrupted my system in just 5 days, reviving my hot flashes. I am stopping it after learning about its effects on estrogen dominance. I regret not researching properly before taking this.

Menopause made easier
When I began experiencing menopause, a friend recommended the book *The Power of Peri Menopause*, which introduced me to Evening Primrose Oil to alleviate symptoms. This product, combined with another for menopause, has made the transition much smoother. After reducing carbs and gluten from my diet, I'm now happier and healthier. I've been off the other product for years, but if I stop taking the Evening Primrose Oil, my hot flashes return. I wholeheartedly recommend it!

Evening primrose oil reduces hot flashes
Improvement in menopausal symptoms with a nutritional product containing evening primrose oil, hop extract, saffron, tryptophan, vitamins B6, D3, K2, B12, and B9.
Significant reduction in symptoms
We investigated how evening primrose oil, as part of the Exelvit Menopause® nutritional product, affects menopausal symptoms, including hot flashes. In a study of 156 menopausal women, participants took the product daily for 12 weeks.

The results showed a significant reduction in hot flashes by 48.15%, along with improvements in other symptoms like sleep disturbances and anxiety. This evidence suggests that evening primrose oil may be a beneficial option for managing menopausal discomfort.

Evening primrose oil aids menopausal symptoms
Efficacy and Safety of Nutraceutical on Menopausal Symptoms in Post-Menopausal Women: A Randomized, Double-Blind, Placebo-Controlled Clinical Trial.
Study shows significant benefits.
We examined the effects of a proprietary blend of herbs, including evening primrose oil, on menopausal symptoms in post-menopausal women. Using a randomized, double-blind, placebo-controlled trial design, 101 women participated in the study over 12 weeks. Our findings revealed significant reductions in hot flashes, sweating, sleep issues, and mood disturbances in the treatment group compared to the placebo. While hormone levels showed no significant change, improvements in health indicators were noted. Overall, this combination of four herbs appears to effectively support women through their menopausal transition.

Mixed evidence for evening primrose oil
The effect of Oenothera biennis (Evening primrose) oil on inflammatory diseases: a systematic review of clinical trials.
Relevance score indicates limited significance
We explored the effects of evening primrose oil (EPO), derived from Oenothera biennis, on various inflammatory conditions through a systematic review of randomized controlled trials. While we found some evidence supporting EPO's benefits for certain disorders like rheumatoid arthritis and menopausal hot flashes, mixed results were common and many conditions showed no significant improvement.

The overall findings highlighted a lack of strong recommendations for EPO due to variations in study results and a need for more high-quality research to clarify its effectiveness in managing inflammatory symptoms.

Instant results
Stopped my hot flashes cold. This is the only product that has succeeded in stopping my horrible hot flashes that kept me awake at night. I had tried everything without success, but I’m so glad I gave this a go. It works, and I no longer wake up drenched in sweat.

Effective relief
Great stuff for menopausal women! I’ve been taking it for about two years, and I can confidently say it alleviates most of my hot flashes. If I miss taking it for a few days, they return, proving its effectiveness against my "personal summers."
