月見草油 Evening Primrose Oil × 經前症候群
結論：證據分歧
EPO 用於 PMS 的整體證據屬「薄弱且偏向無效」：方法學最嚴謹的 Budeiri 1996 MA 與 Khoo 1990 RCT (n=38, crossover) 皆未顯示優於安慰劑；Sultana 2022 SR 雖納入但 EPO 專屬效應量無法萃取，正向結論由其他藥草驅動；Mahboubi 2019 屬非系統性敘事綜述、品質低。

EFSA 明確拒絕 PMS/menstrual discomfort 健康宣稱 (ID 495/640/1773/1775)，NCCIH 判定 insufficient，Mayo/Cleveland 僅以「可能有幫助」軟性提及但不背書，Harvard/ACOG 不討論。
整體支持「機轉合理 + 少量人體研究但學會視為 insufficient evidence」的 C 級錨點；尚未到 Cochrane 級反證據的 D 級（PMS 領域並無 EPO 專屬 Cochrane）。

A Systematic Review and Meta-Analysis of Premenstrual Syndrome with Special Emphasis on Herbal Medicine and Nutritional Supplements
結論：Sultana et al. SR/MA of herbal/nutritional supplements for PMS identified only ONE EPO RCT (Saki 2015, n=80) which reported significant symptom relief vs placebo with no adverse events; pooled EPO-specific effect size was not extractable because EPO was represented by a single small trial, so the review's positive conclusion is dominated by other herbs (Vitex, saffron) not EPO itself.

Is evening primrose oil of value in the treatment of premenstrual syndrome?
結論：Budeiri et al. meta-analysis: inconsistent scoring across trials prevented rigorous pooling, but the two most methodologically rigorous trials failed to show any beneficial effect of EPO vs placebo; conclusion stated EPO is of little value in management of PMS (no extractable summary p-value or SMD reported).

Evening primrose oil and treatment of premenstrual syndrome
結論：Khoo et al. RCT (n=38, 6 cycles, crossover): no significant difference between EPO and placebo on any of the 10 symptom scores over six cycles; improvement was rapid in cycle 1 then partially reversed after crossover regardless of arm, leading authors to attribute the response to placebo effect in moderate PMS.

Evening Primrose (Oenothera biennis) Oil in Management of Female Ailments
結論：Mahboubi narrative review (Journal of Menopausal Medicine, DOI 10.6118/jmm.18190) reported that across the small EPO PMS trials, severity scores fell from ~53.2 to ~33.6 after 3 months of EPO while placebo barely changed; concluded EPO is effective for PMS BUT explicitly cautioned this is a narrative (not systematic) synthesis and that effects require 4-6 months of regular use — conclusion conflicts with the 1996 Budeiri MA which rated the same body of evidence as insufficient.
