HealthWatchlist is written and edited by John and independently published by Ping Media Group Ltd. This policy explains how subjects are selected, how evidence is judged and where the limits of the work lie.
Who is responsible for the content?
I am responsible for the research, wording and editorial conclusions on HealthWatchlist. I am an independent researcher and editor, not a doctor, pharmacist or toxicologist. Articles are not presented as medical advice or as a substitute for an assessment by a qualified professional.
HealthWatchlist does not currently use a routine clinician-review process. That limitation is stated openly because an unexplained badge or vague claim of expert review would give readers false reassurance. If a named specialist reviews a future article, the page will identify the reviewer, their relevant qualification and the scope of the review.
How subjects are chosen
Subjects come from reader questions, search demand, old HealthWatchlist links and recurring product claims. Search interest affects the order of work, but it does not decide the answer or make a topic safe to publish. Claims involving cancer, serious infection, pregnancy, children or delayed medical care are subject to a higher publication threshold and may remain unpublished.
Evidence hierarchy
I begin with the exact claim, preparation, route and outcome. An essential oil, a plant extract, a food, an isolated molecule and a finished cosmetic are not treated as interchangeable.
For health effects, the preferred sources are systematic reviews, clinical guidelines, regulatory assessments and relevant controlled human studies. PubMed Clinical Queries and Cochrane’s systematic reviews are useful starting points, but each relevant paper is still read for its participants, intervention, comparator, outcomes and limitations.
Laboratory and animal studies can explain why a question deserves research. They cannot, by themselves, show that an oil treats a person. Traditional use is reported as history, not as proof of effectiveness.
Citations and wording
A sentence that describes a study or authoritative conclusion should link directly to that paper, review or official source. Source lists support further checking, but they do not replace inline citations. I report conflicting and negative findings when they are relevant and avoid turning statistical significance into a promise of meaningful benefit.
Headlines and summaries should match the evidence beneath them. HealthWatchlist does not use words such as proven, cure or guaranteed unless the underlying evidence and regulatory context genuinely justify them.
Commercial independence
Manufacturers and retailers do not supply HealthWatchlist evidence scores or verdicts. Payment, advertising, gifts or affiliate arrangements must not improve an assessment. Any commercial relationship connected with a page should be disclosed clearly under the Affiliate Disclosure.
Research and publishing tools
Software tools help to locate, compare, organise and publish information. They do not decide the conclusion. I check the claim against the cited sources, edit the prose and take responsibility for the finished page. A confident automated summary is not evidence.
Updates and corrections
Pages may be updated when stronger evidence, new safety advice or a changed product label affects the conclusion. Material errors are handled under the Corrections Policy. Readers can report a concern through the Contact page.
