Evidence methodology
Evidence grades apply to defined claims, not entire ingredients, products or traditions. Traditional Ayurvedic use remains a separate category and commercial relationships cannot alter grades.
Claim-level assessment
Each evidence assessment receives a stable claim ID, a grade, a rationale, limitations and at least one supporting source. Changing the evidence set changes the publication revision fingerprint and invalidates earlier approvals.
Evidence grades
- A · Strong evidence
- B · Good evidence
- C · Emerging evidence
- D · Preliminary evidence
- T · Traditional use
- U · Unsupported / insufficient
- R · Risk / avoid
Source hierarchy
Guidelines, systematic reviews, randomized trials, authoritative safety references and well-designed observational evidence are preferred according to the claim being evaluated. Marketing copy cannot establish clinical efficacy.
Ayurveda
Traditional-use claims can be graded as traditional context when credible classical, official or academic provenance exists. Modern efficacy claims require modern clinical evidence. One category is not silently upgraded into the other.
Review gates
Editorial, evidence, medical, Ayurveda and commerce reviews are required according to content type and risk. Approvals are bound to the exact content and evidence revision being published.
