HealthWatchlist is an independent, evidence-led guide to the claims made for essential oils: what looks promising, what remains unproven and where caution matters.
About me
I am John Hamlen, the founder and editor of HealthWatchlist. I am an open-minded sceptic and independent researcher, not a clinician. I find the relevant research, read it critically, explain its limits and take responsibility for the site’s editorial judgements. You can also read how I assess essential-oil evidence.
Why essential-oil claims need closer scrutiny
The internet is full of confident lists promising that one oil can solve many unrelated problems. HealthWatchlist takes a slower approach: define one precise claim, examine the available human evidence and publish a clear verdict with the sources used.
Editorial principles
- Be sceptical without deciding the answer in advance.
- Prefer authoritative reviews and human research to anecdotes or laboratory results.
- Report negative and conflicting findings, not only supportive studies.
- Keep traditional use, evidence of effect and safety as distinct questions.
- Correct material errors and show when an assessment was last reviewed.
How the site is produced
I use research, data and publishing tools to collect, compare and organise information efficiently. Those tools support the work, but they do not make the editorial judgement. I review what HealthWatchlist publishes and take responsibility for its conclusions.
Independence and ownership
HealthWatchlist is independently published by Ping Media Group Ltd. Its evidence assessments, verdicts and editorial priorities are not supplied by essential-oil manufacturers or sellers.
