黑種草籽 Black Seed × 氣喘
The evidence for black seed (Nigella sativa) as an asthma intervention is real but limited.
The evidence for black seed (Nigella sativa) as an asthma intervention is real but limited. Two meta-analyses (PMID 34658694, 31892440) pooling only 4 RCTs and roughly 187 subjects consistently found significant improvement in Asthma Control Test scores (SMD ~0.50) and FEV1 (SMD ~1.84), but the FEV1 confidence interval is extremely wide (0.07 to 3.60), indicating high heterogeneity and imprecision, and PEF showed no benefit. The only moderate-quality RCT (PMID 28093815, MRC-funded) showed a modest ~1.5-point ACT gain over placebo, while the others were low quality with undisclosed funding and heterogeneous, ill-defined preparations. Critically, every trial used black seed as an add-on to maintenance inhaled controller therapy, never as a replacement, and major asthma authorities (GINA, ATS) do not name or endorse it. Cleveland Clinic is the only consumer-health body addressing the pair and is only cautiously supportive, stressing it is not a substitute for controller medication. This is a textbook grade C: genuine signal exists but the body of evidence is small, inconsistent, and uncertain.

- compute_raw_score — 加權公式: L2×0.30 + L3×0.25 + L5×0.25 + L11×0.10 + L1×0.10 = 0.573
- 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
台灣社群幾乎無「黑種草籽用於氣喘」的討論；零星心得集中在過敏性鼻炎與美容，且有人反映服用後過敏/濕疹加重。此題被商業業配文與代工廠行銷霸佔，社群原生訊號薄弱。
無共識（針對氣喘無相關討論；過敏面向反應分歧，含負面個案）
- 臉部過敏泛紅
- 原有濕疹加重
- 草味／油味重、喉嚨刺激感
- 吸入型皮質類固醇（含 ICS-formoterol）
- 長效型乙二型交感神經興奮劑（LABA）
- 觸發因子與過敏原迴避
