銀杏 Ginkgo Biloba × 周邊循環／間歇性跛行
結論：證據不足
周邊循環（間歇性跛行）面的最高階證據是 Cochrane Nicolai 2013（14 試驗、n=739），其步行距離增加未達統計顯著（P=0.

周邊循環（間歇性跛行）面的最高階證據是 Cochrane Nicolai 2013（14 試驗、n=739），其步行距離增加未達統計顯著（P=0.06，CI 跨零），明評為無臨床意義效益；兩項 PAD RCT（Gardner 2008、Wang 2007）也都未達顯著、且 Wang 顯示加銀杏不優於單純運動。
早期 Pittler & Ernst 2000 MA 雖有統計正向（34 m），但作者自評幅度小、臨床意義不確定，且已被 Cochrane 取代。
機轉合理（萜類擴張血管/抗血小板）且有微弱、方向一致的訊號，但無任何高品質研究確立臨床效益——符合 C 薄弱證據錨點；不給 B 是因唯一最高階證據（Cochrane）為陰性、學會全面不背書。

Ginkgo biloba for intermittent claudication (Cochrane Review)
結論：Pooled ACD increased by 3.57 kcal (~64.5 m on flat treadmill at 3.2 km/h) but did not reach statistical significance (P = 0.06); CI crossed zero.

Ginkgo biloba extract for the treatment of intermittent claudication: a meta-analysis of randomized trials
結論：Pooled pain-free walking distance favored ginkgo by a weighted mean difference of 34 m; authors judged the effect modest and of uncertain clinical relevance.

Effect of Ginkgo biloba (EGb 761) on treadmill walking time among adults with peripheral artery disease
結論：Maximal walking time rose +91 s with ginkgo vs +20 s with placebo, a modest but non-significant difference (P = 0.12); authors stated data do not support ginkgo as effective PAD therapy.
前往 PubMed
Supervised exercise training combined with ginkgo biloba treatment for patients with peripheral arterial disease
結論：Adding ginkgo to supervised exercise training produced no greater benefit on walking performance than exercise training alone.

📍立場總覽
周邊／末梢循環（循利寧的核心適應症）是台灣社群討論銀杏最對症、訊號最強的用途。PTT 藥版（Pharmacy）討論最深入也最乾淨：藥師共識認為銀杏葉萃取物作用於末梢血管擴張，對四肢冰冷、麻木、暈眩等末梢循環障礙『有改善緩解』，但反覆強調它『只能預防栓塞、不能溶解已存在的血栓』，血管已阻塞者效果有限，且循利寧屬處方/指示藥、循環不良成因多，應先就醫釐清而非自行購買。藥師也指出循利寧『貴在廣告費』，台廠學名藥銀杏葉萃取物成分相近、自費也便宜很多。Mobile01 養生板則以品牌與價格比較為主（循利寧 ~2000 vs 台廠 ~1000），業配/比價密度較高。
💬社群實感
分歧偏中性：周邊／末梢循環是循利寧的正式適應症，故討論最對症且多由醫師開立或藥師推薦；藥版專業共識認為對四肢冰冷、麻木等末梢循環障礙『有改善緩解』，但親身『有感』的具體實測心得仍稀少、且難與保暖／運動等因素切割，多數論述為轉述機轉而非個人量化體感。
破解迷思 社群最常見的 6 個誤解
✕
迷思誤以為銀杏能『溶解血栓、打通已阻塞的血管』
✓
事實藥師明確澄清銀杏葉萃取物『不能溶解血栓，只有預防血栓的作用』，血管已堆積阻塞者頂多預防再惡化
✕
迷思誤以為循利寧是『末梢循環特效藥』、自行買來吃就好
✓
事實藥師指出它是處方/指示藥，且循環不良成因多，應先就醫釐清病因
✕
迷思誤以為『滴個三五天就見效』
✓
事實藥師指出末梢循環/耳部症狀改善通常需 1-2 個月才有感
✕
迷思把循利寧『滴劑』當外用滴入患部/耳朵
✓
事實實為口服滴劑（給不便吞錠者用），非外用
✕
迷思誤以為銀杏果（白果／循福之類）與銀杏葉萃取物功效相同
✓
事實有研究實證的是銀杏『葉』，銀杏果有效成分低且可能殘留未去除的銀杏酸過敏物質
✕
迷思誤以為進口循利寧成分更強
✓
事實藥師指『貴在廣告費』，台廠學名藥銀杏葉萃取物成分相近
