# Ginger dry extract × Migraine—evidence sheet on reduced severe-pain days, acute analgesic use, or attack duration Verdict 3009 · Evidence Check Stored-material review date: Not recorded Original evidence cut-off: 2026-09-07 Review-criteria version: 1.0 Public page/material preparation date: 2026-10-20 Clinical papers were not read directly; existing review summaries were checked. No new clinical-literature search was performed. Unverified does not mean that research is absent or that there is no effect. ## Assessment scope - Population: The stored account concerns a placebo-controlled trial of 107 adults with episodic migraine. Overall size is not transferred into arm-specific analysis counts or attack, diary or harms denominators for individual pain outcomes. Diagnosis, baseline severity, concurrent care, eligibility and arm-specific characteristics are unverified. - Ingredient, formulation and route: The original intervention is single-ingredient oral ginger dry extract standardized to 5% active constituents. This is not converted into a specific gingerol content or equivalence with culinary ginger, acute combination products or other formulations. Product, constituent markers, manufacturing, batch and placebo details are unverified. - Dose: The original study schedule of dry extract 200 mg, 3 times daily for 3 months is preserved. Total daily or active-constituent amounts are not calculated or converted into personal dosing or an optimal dose. Actual exposure, adherence and product-specific quantitative details are unverified. - Comparator: The direct control is placebo. Within-arm improvement is distinguished from added ginger benefit over placebo. Placebo composition, blinding, concurrent or changed preventive and acute medications, and matching of care remain unverified. - Measured outcome: The selection is reduced severe-pain days, acute analgesic use, or attack duration. Original subclaim D and the explanation of within-arm changes without between-arm advantage are retained. The parent responder outcome is not transferred as the same effect or denominator; individual definitions, units, effects, CIs and analysis details are unverified. - Duration: The trial concerns 3-month single-ingredient prevention, distinguished from acute-attack treatment. Baseline, visit, attack and measurement windows for each outcome, post-treatment persistence and long-term or rare harms are unverified. Observation duration is not extended into an exact harms timeline or verification of long-term effects. - Questions outside this scope: Do not convert within-arm improvement into added ginger benefit over placebo.; Do not transfer the parent 50% responder threshold or denominator to pain days, analgesic use or duration.; Do not add sharing across the same report, outcomes, parent and subclaims as new independent trial, participant or event totals.; Do not combine acute feverfew combinations, sumatriptan controls or nausea signals as replication of the same single-ingredient prevention question.; Do not create new total daily or active-constituent amounts, medication discontinuation, replacement, dosing or treatment guidance. ## Checklist items ### N01 · What is the selected pain-related question?

Individual definitions, denominators, direct estimates, CIs, diaries, prespecified hierarchy and concurrent-care details are unverified. Parent scores and historical support checking are separate contexts. Independent replication: The original Martins prevention report is shared across parent, responder and pain-related outcomes. The 107 adults and original sole-direct-prevention-trial statement retain separate contexts; outcomes do not add new independent replication, participants or events. Unique trial, participant and event totals are unverified. | Material | Public availability | Access status | Actually read | Notes | |---|---|---|---|---| | Stored existing review summary | Preserved copy of the complete parent-verdict stored summary | Stored summary | Summary read | Preserve original PMID31398997, DOI10.1177/0333102419869319 and NCT02570633.

They do not constitute official assessment-tool certification or a new efficacy score. - M03 [Cochrane Handbook 6.5 (2024), chapter updated 2023-08](https://www.cochrane.org/authors/handbooks-and-manuals/handbook/current/chapter-03) · §3.1, §3.2.1–3.2.3, MECIR C5/C7/C13 · Clearly record the question, eligibility conditions and reasons for changes, and distinguish variations in interventions. · Existing methodological links were reused for production. External originals were not reread and methodological content was not reassessed. - M04 [Cochrane Handbook 6.5.1 (2025), chapter updated 2025-03](https://www.cochrane.org/authors/handbooks-and-manuals/handbook/current/chapter-04) · §4.5, §4.6.1–4.6.3, MECIR C42 · Distinguish studies from reports and link them; do not omit a study solely because results are unreported. · Existing methodological links were reused for production. External originals were not reread and methodological content was not reassessed. - M08 [Cochrane Handbook 6.5 (2024), chapter updated 2019-10](https://www.cochrane.org/authors/handbooks-and-manuals/handbook/current/chapter-08) · §8.1–8.2.3, Table 8.2.a · Define the outcome and effect of interest, then examine randomization, deviations, missing data, measurement and selective reporting. · Existing methodological links were reused for production. External originals were not reread and methodological content was not reassessed. - M15 [Cochrane Handbook 6.5 (2024), chapter updated 2023-08](https://www.cochrane.org/authors/handbooks-and-manuals/handbook/current/chapter-15) · §15.2.4, §15.3.1–15.3.3 · Distinguish effect estimates, intervals, importance and applicability. Sample size alone does not determine precision. · Existing methodological links were reused for production. External originals were not reread and methodological content was not reassessed. - M19 [Cochrane Handbook 6.5 (2024), chapter updated 2019-10](https://www.cochrane.org/authors/handbooks-and-manuals/handbook/current/chapter-19) · §19.1.2, §19.2.1–19.2.4 · Harm questions may require different designs, populations and follow-up from efficacy questions. Case reports do not establish incidence rates. · Existing methodological links were reused for production. External originals were not reread and methodological content was not reassessed. ## What the statuses mean - Partly verified: Partial information from the stored summary is linked; detailed originals and content review remain incomplete. - Unverified: Required details cannot be established within the preserved scope. This does not establish absence of effects or studies, or safety. - Review incomplete: Review of existing content remains incomplete. - Met: This state is used only within the relevant conditions after material verification and content review. It was not automatically assigned in this work. - Not reported: Unreported within material actually read. Unread external material is not relabeled as unreported. - Inaccessible: This means actual access failure. External access was not attempted in this work, so this state was not assigned. - Not applicable: Used only with an application exception and reason based on the question scope. - Conflicting data: This requires actual comparison of materials; no new conflict judgment was made in this work. - Insufficient evidence for the conditions: This indicates gaps in additional material for the selected conditions. Unread material as a whole is not converted into an efficacy grade. ## Change history 2026-10-20 · Public page/materials 1.0.
