蘆薈 Aloe Vera × 第二型糖尿病
Three meta-analyses and one umbrella review (L2) consistently show oral aloe vera lowers HbA1c by roughly 0.
Three meta-analyses and one umbrella review (L2) consistently show oral aloe vera lowers HbA1c by roughly 0.4-1.05% and reduces fasting glucose in type 2 diabetes and prediabetes, with the largest effect in poorly-controlled patients (baseline FBG >=200 mg/dL). However, every underlying trial is small (per-MA totals 89-470 patients), preparations and doses are non-standardized, heterogeneity is high, statistically significant publication bias was detected for fasting glucose, and several author teams explicitly call their own results inconclusive. Critically, the American Diabetes Association Standards of Care explicitly names aloe vera and states it is not recommended for glycemic benefits (L5e), and no other reviewed clinical body (Mayo, Cleveland, Harvard, NCCIH) endorses it for glycemic control. Examine's HbA1c grade B reflects the meta-analytic signal but, in my independent judgment, overweights a consistent pooled estimate built on low-quality trials with detected bias and contradicted by an explicit society non-recommendation. Weighing a real but fragile efficacy signal against trial-quality limitations and an explicit negative guideline, the totality of evidence supports grade C: a genuine effect may exist but is uncertain and not robust enough to recommend.
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 = 0.557
- 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 BeautySalon/regimen/FITNESS、Dcard、Mobile01）對「蘆薈」的討論幾乎全集中在蘆薈膠／蘆薈露的護膚、曬後鎮定用途，找不到鄉民將蘆薈用於控血糖或第二型糖尿病的真實實測心得。唯一將「蘆薈+血糖」連在一起的內容，多為商業健康媒體與 SEO 懶人包（如 healthyD、pure-au 假借『PTT推薦』、Bowtie）所製造的業配文，並非社群真實經驗。康健等衛教則反向提醒蘆薈素（aloin）過量恐致腹瀉與肝腎毒性。
無共識（社群無蘆薈用於控血糖／糖尿病的真實實測心得；蘆薈討論幾乎全為護膚的蘆薈膠／蘆薈露，與血糖無關）
- 腹痛、腹瀉（衛教轉述：蘆薈素 9~15 克即可能引發，非鄉民親身回報）
- 蛋白尿、心跳過緩、肝腎毒性（衛教轉述，長期或過量食用）
- 醫療營養治療與減重
- 規律身體活動
- Metformin（二甲雙胍）
