沙雷肽酶 Serrapeptase × 慢性支氣管炎
The entire clinical case for serrapeptase in chronic bronchitis / airway mucus rests on a single 2003 open-label trial (Nakamura, PMID 12911824, n=29) with a no-treatment rather than placebo control and no blinding, which makes it highly vulnerable to placebo effect and observer bias.
The entire clinical case for serrapeptase in chronic bronchitis / airway mucus rests on a single 2003 open-label trial (Nakamura, PMID 12911824, n=29) with a no-treatment rather than placebo control and no blinding, which makes it highly vulnerable to placebo effect and observer bias. The 2013 systematic review (PMID 23380245) of 24 efficacy studies explicitly concluded the evidence base is of poor methodological quality. Decisively, the original manufacturer Takeda voluntarily withdrew Danzen (serrapeptase) from the Japanese prescription market in 2011 after a larger double-blind placebo-controlled postmarketing trial failed to show any benefit over placebo for difficulty expectorating, and Singapore phased it out for lack of substantive evidence. No respiratory society (ATS, CHEST) names serrapeptase in any guideline, and neither Mayo, Cleveland Clinic, nor Harvard publishes on it. When the best available higher-quality evidence (a double-blind RCT) is negative and a low-quality open-label trial is the only positive signal, the honest grade is D: a weak claim that is not merely unproven but actively contradicted by the strongest data.
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 = 0.327
- tier_from_score — 依分數區間映射至 tier letter
- apply_hec_rules — 無高階證據可裁決
- 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/FB/痞客邦）幾乎查無「沙雷肽酶（鋸齒酵素）用於慢性支氣管炎」的鄉民實測討論。原因是此成分在台灣長期屬醫師處方/OTC 西藥而非保健品，民眾多由診所開立、缺乏自行購買比較的社群分享動機；且 TFDA 早於 2006 年認定其療效缺乏足夠臨床證據、多張藥證到期後不予展延，使其逐漸退出市場。現存中文資訊集中於藥品查詢站、藥師公會與新聞，而非社群實測心得，故無在地經驗可萃取。
無共識（社群幾無針對慢性支氣管炎的實測心得；屬處方/OTC 老藥，非保健品討論標的）
