葡萄籽萃取 Grape Seed Extract × 末梢循環
The peripheral-circulation evidence base for grape seed extract is small, low-quality, and internally inconsistent.
The peripheral-circulation evidence base for grape seed extract is small, low-quality, and internally inconsistent. Examine has no dedicated circulation block (a coverage gap); the condition is only fuzzy-mapped to single-study C-grade 'Blood Flow' surrogates (n=17 and n=36) and a tiny 'Leg Edema' outcome (n=8). The L2 chronic-venous-insufficiency / leg-vein trials are either open-label without a placebo arm (VICTORY 2026, n=176 — high performance/detection bias on subjective scores), small pilots with no between-group test (4D-flow-MRI study, n=23), or industry-funded healthy-volunteer crossover studies (2013). Critically, the objective vascular endothelial endpoint, flow-mediated dilation, was NULL in a 19-trial meta-analysis (WMD +1.02%, 95% CI -0.62 to 2.66), EFSA rejected the OPC chronic-venous-insufficiency health claim in 2010, and no professional society (AHA, SVS) endorses it. The honest reading is preliminary, low-certainty signal on subjective venous symptoms with a negative objective endpoint — a C grade, not B.
評分透明度
所有分數由 7 層證據引擎計算，過程公開可查▸查看完整決策路徑（audit trail）
- compute_raw_score — 加權公式: L2×0.30 + L3×0.25 + L5×0.25 + L11×0.10 + L1×0.10 = 0.485
- tier_from_score — 依分數區間映射至 tier letter
- apply_hec_rules — 高品質 SR/MA 顯示 positive (1 篇 > 0 negative)
- tier_strict_requirement_check — Tier 條件達標，未降階
- detect_disputes — 偵測到 0 個 hard + 0 個 soft dispute
- decide_status — 依 tier + dispute 結果決定 status
台灣社群（PTT/Dcard/Mobile01）對葡萄籽萃取的真實討論幾乎集中在『美白/皮膚透亮』與抗氧化美容用途，由 BeautySalon、regimen 板的心得文帶起；針對『末梢循環/手腳冰冷』這個適應症，幾乎沒有原生鄉民實測心得。真正討論手腳冰冷的串（Dcard 閒聊/女孩板、Mobile01 保健板）主流推薦的是薑茶、泡腳、壓力襪、運動與四物，而非葡萄籽。葡萄籽→強化血管/改善血液循環/靜脈曲張/水腫的論述，幾乎全來自品牌部落格、Vocus/痞客邦業配整理文與健康2.0 等商業媒體（即 prompt 警告的業配污染），社群匿名實證訊號薄弱。因此此 condition 屬於『社群討論稀少、商業內容主導』，stance 設 not_addressed，confidence 偏低。
無共識（針對末梢循環/手腳冰冷幾乎無原生社群實測心得；葡萄籽的社群討論主流為美白與抗氧化美容用途）
