Verdict 3028 · Evidence Check

Stored-material review date: Not recorded  
Original evidence cut-off: 2026-09-08  
Review-criteria version: 1.0  
Public page/material preparation date: 2026-10-23

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 population is adult men with seasonal allergic rhinitis. Specific age, diagnosis, sensitization testing, allergen, eligibility and baseline characteristics remain unverified. Applicability to women, children or perennial rhinitis is not assumed.
- Ingredient, formulation and route: This is an oral combination capsule of supercritical-extracted Nigellin Amber seed oil standardized to 5% thymoquinone and BioPerine piperine. Batch measurements, excipients, quality and product identity remain unverified.
- Dose: The original record is 250 mg seed oil and 2.5 mg piperine 2 times daily. Dosing times, adherence and actual exposure remain unverified. No new constituent daily total, cumulative dose, optimal dose or individual dosing guidance is created.
- Comparator: The comparison is matched-appearance placebo. Placebo ingredients, taste/smell, maintained masking, common management and permitted/arm-specific rhinitis or rescue medicines remain unverified. This is not converted into a comparison with Nigella-oil-only or piperine-only arms.
- Measured outcome: The selected question is change in TNSS at 15 days. The original description of TNSS and symptom duration as coprimary outcomes is retained without filling the symptom-duration result. Scale range, measurement methods, prespecified success criteria, important difference and original intervals remain unverified.
- Duration: The original record is 15 days of treatment and follow-up. Interim visits, persistence after discontinuation, management across the season and long-term follow-up remain unverified. This is not converted into a numerical improvement in symptom duration or long-term prevention.
- Questions outside this scope: The selected question concerns the fixed standardized Nigella-oil and piperine combination product. The separate contributions of Nigella oil, piperine and thymoquinone, and effects of other formulations, remain distinctly unverified.; The existing C·50 points·Caution, B/P/R1/I0/E+/B2/C0 and evidence date 2026-09-08 are retained. Historical cross-checking wording and assessment records do not establish new independent clinical validation or completed review here.; TNSS 8.45→4.94 versus 7.69→6.66 and the reported changes −3.52 versus −1.03, P<.001 are separately retained. Starting/final values are not subtracted to revise reported changes or calculate new between-group effects, intervals, percentages or NNT.; The original record of 65 people, 33 versus 32, all completing and all male is retained. Direct arm mapping and endpoint-specific analysis denominators remain unverified; completion is not converted into no missing results, verified ITT or no adverse events.; The original TNSS/symptom-duration coprimary wording and existing separation setting are both retained. TNSS significance alone does not establish overall success or fill the symptom-duration result.; The original citation’s CTRI/2022/07/044180 and PMCIDPMC11315530 are separate from content reading. The English-placeholder correction date 2026-09-14 is not converted into current external verification or a new verdict date.; The no-funding statement remains separate from Sami-Sabinsa/Sabinsa employee authorship and product involvement. Company-related records are not converted into new independence certification or proof of no effect.; Short-term male combination-product results are not extended to women, children, perennial rhinitis, medication sparing, management across the season, prevention or treatment replacement. Original caution about product differences, vulnerable groups, surgery and medicines remains; no new harm rate, causality, contraindication or overall safety judgment is made.

## Review criteria and methods

These are Chamgap's own application conditions, informed by the relevant sections of official methodological guidance. 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.
