石榴 Pomegranate × 高血壓
Three meta-analyses (8, 14, and 22 RCTs) consistently show pomegranate juice significantly lowers systolic BP by roughly 5-8 mmHg and diastolic BP by roughly 2-3 mmHg, with the directionality of effect agreed upon across syntheses.
Three meta-analyses (8, 14, and 22 RCTs) consistently show pomegranate juice significantly lowers systolic BP by roughly 5-8 mmHg and diastolic BP by roughly 2-3 mmHg, with the directionality of effect agreed upon across syntheses. However, the evidence does not reach grade B because of three concrete weaknesses: very high statistical heterogeneity (SBP I2 around 90%, DBP I2 around 91.8%) that materially undermines the pooled point estimates; a 2017 qualitative systematic review (PMID 29173650, 619 participants) finding only a minority of RCTs reached significance and judging the evidence weak; and largely undisclosed funding raising unresolved industry conflict-of-interest concerns. The effect size is modest and clinically meaningful mainly in pre/hypertensive subgroups, and the FDA's 2010 warning letter to POM Wonderful specifically cited the blood-pressure claim as an unapproved drug claim. A genuine, reproducible signal exists but its magnitude and clinical certainty remain uncertain, which is the definition of grade C.
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 = 0.653
- tier_from_score — 依分數區間映射至 tier letter
- apply_hec_rules — 高品質 SR/MA 顯示 positive (4 篇 > 0 negative)
- tier_strict_requirement_check — Tier 條件達標，未降階
- detect_disputes — 偵測到 1 個 hard + 0 個 soft dispute
- decide_status — 依 tier + dispute 結果決定 status
台灣社群（PTT Health/regimen/FITNESS/Drink/BeautySalon、Dcard、Mobile01、FB 社團、痞客邦）幾乎無「石榴／紅石榴用於高血壓」的第一手鄉民實測心得。石榴在 PTT 的足跡多屬果汁試飲（Drink 板）、香水（Jo Malone 黑石榴）、美容保養（每日營養品）等泛論，極少有人針對降血壓貼出自己的血壓數據前後對照。在 Health 板問「清血管保健品」的串中，鄉民推薦的是亞脈通、純 EPA 魚油，完全沒提到石榴。『50ml 石榴汁可降血壓 5%』『每日石榴汁降收縮壓』這類說法幾乎全來自商業健康媒體與保健品電商部落格（元氣網、healthyD、hk01、悠活原力、機本生活、crassna、helloyishi、95dan 等）的功效條列與導購文，而非匿名辯證式的在地經驗。屬該 condition 下社群討論稀少、業配污染高的標的，無共識可供萃取。
無共識（台灣社群對石榴用於高血壓幾無第一手實測討論；現有討論集中於抗氧化、美容、果汁試飲而非降血壓）
- DASH 飲食
- 規律有氧運動
- 降血壓藥物
