Editorial · Transparency
The Health Reference is an independent clinical reference for medicinal plants, dietary supplements, and natural medicine. Every page is built on primary peer-reviewed literature — not marketing claims, not anecdote, not tradition presented as evidence.
Our Mission
The supplement and herbal medicine space is saturated with content written to sell — not to inform. Product reviews dressed as clinical guides. Affiliate roundups disguised as encyclopedias. Health claims sourced from manufacturer whitepapers rather than peer-reviewed trials.
The Health Reference was built to be the opposite. Every monograph on this site begins with the primary literature: PubMed-indexed randomised controlled trials, meta-analyses, pharmacokinetic studies, and regulatory assessments from the European Medicines Agency, the World Health Organisation, and national pharmacopoeias. Traditional use is documented accurately but never presented as clinical evidence.
When a study is inconclusive, we say so. When the evidence is weak, the evidence grade reflects that. When a supplement has documented safety risks or drug interactions, those are listed prominently — not buried in a disclaimer footnote. The goal is not to make natural medicine look good or bad. The goal is to represent what the science actually says, precisely.
Where affiliate links appear on this site, they are clearly disclosed and restricted exclusively to products that meet documented third-party quality testing standards. Commercial relationships never influence the clinical content of any monograph. The medicinal plants encyclopedia and supplements reference are written to the same standard, regardless of whether a product exists to be recommended.
Editorial Position
This site occupies a specific niche: clinical reference, not wellness content. The writing register is institutional and precise. Pharmacological terminology is used accurately, not approximated for general audiences. Readers are assumed to be capable of engaging with clinical information directly.
At the same time, every page is accessible to a motivated non-specialist. Where technical terminology is unavoidable, it is defined in context. The dual audience — general public and health professionals — is served simultaneously, not compromised for either.
"The supplement industry spends billions telling people what they want to hear. This reference tells people what the evidence says."
How Content Is Produced
Every monograph on this site follows the same structured research and writing protocol, applied without exception.
Each monograph begins with a systematic search of PubMed/MEDLINE, the Cochrane Library, and EMBASE for all relevant RCTs, systematic reviews, meta-analyses, and pharmacokinetic studies. Search terms include the plant's common name, accepted Latin binomial, and principal active constituents. No publication date cutoff is applied — historical clinical data is included where relevant to pharmacological context.
Dosage, safety, and contraindication data is cross-referenced against the European Medicines Agency (EMA) HMPC monographs, WHO Monographs on Selected Medicinal Plants, the German Commission E, the European Pharmacopoeia, and national regulatory documents where available. Discrepancies between regulatory bodies are noted explicitly in the monograph text.
Each primary clinical indication carries an evidence grade following criteria comparable to those used by the Natural Standard Research Collaboration. Grade A reflects consistent, high-quality RCT evidence. Grade B reflects multiple positive trials with some inconsistency. Grade C reflects limited or conflicting clinical data. Grades are assigned conservatively — when evidence is borderline, the lower grade is applied and limitations are stated.
Adverse event profiles, contraindications, and drug interaction data are reviewed from clinical trial safety data and post-market surveillance sources including LiverTox (NIH/NIDDK), the WHO Uppsala Monitoring Centre pharmacovigilance database, and published case reports. No plant is presented as inherently safe — safety is always contextual, dose-dependent, and population-specific.
Clinical findings are described with precision throughout. "Studies suggest" replaces "proven to." "May reduce" replaces "reduces." Study limitations — sample size, duration, population specificity, blinding quality — are noted where material to interpretation. Superlatives are avoided unless directly supported by comparative data in the cited literature.
Every monograph carries a Last Updated date. As new RCTs, meta-analyses, or regulatory guidance are published, relevant monographs are reviewed and updated accordingly. Evidence grades, dosage recommendations, and safety data are subject to revision without notice. The publication date of each cited study is visible in the reference list, allowing readers to assess recency independently.
Primary Sources
The Health Reference draws exclusively on publicly accessible, peer-reviewed, and regulatory-grade sources. No manufacturer-funded white papers, no unpublished data, and no proprietary industry studies are cited as primary evidence for any clinical claim.
U.S. National Library of Medicine's primary biomedical literature database. The first-line source for all RCTs, meta-analyses, and pharmacokinetic studies cited in monographs.
The European Medicines Agency's official herbal monographs. The gold standard for evidence-based traditional use approval and dosage guidance across the European Union.
The World Health Organisation's peer-reviewed monograph series covering pharmacology, clinical evidence, safety, and dosage for internationally used medicinal plants.
The German federal regulatory authority's expert committee monographs on herbal drugs — the foundational evidence standard for European phytomedicine for over four decades.
The National Institute of Diabetes and Digestive and Kidney Diseases' database of drug-induced liver injury, including herbal and dietary supplements. Referenced for all hepatotoxicity data.
The French-language clinical phytotherapy reference used by pharmacists and physicians. A primary source for European pharmacopoeia data and traditional use documentation.
Some pages on The Health Reference contain affiliate links to supplement products. When a visitor purchases through one of these links, The Health Reference may earn a commission at no additional cost to the purchaser. Affiliate relationships never influence the clinical content of any monograph. Evidence grades, safety data, dosage recommendations, and drug interaction summaries are determined solely by the primary literature — not by commercial relationships. Affiliate links are restricted to brands with documented third-party quality testing, including certificate of analysis transparency and current Good Manufacturing Practice (cGMP) certification. All affiliate content is clearly identified on each page.
The content published on The Health Reference is produced for educational and professional reference purposes only. It does not constitute medical advice, clinical diagnosis, or individualised treatment guidance. No content on this site should be used as a substitute for consultation with a qualified physician, pharmacist, registered dietitian, or other licensed healthcare provider. Supplement use — particularly in the context of existing medical conditions, pregnancy, lactation, or concurrent pharmaceutical therapy — requires professional supervision. The Health Reference accepts no liability for decisions made on the basis of content published on this site.
