Every claim here is graded by how strong the evidence actually is — and linked to the source so you can check it yourself. Where the science is thin, we say so.
Tap a grade to see what it means. We never call something proven when it isn’t.
Filter by oil, by what you want it for, or by how strong the proof is. Open any card to read the plain-English finding and jump straight to the study.

Study counts reflect our internal research database (235+ studies across the range). Figures are honest tallies, not marketing claims; individual uses link to PubMed.
No clever wording. We read what exists, weigh how strong it is, and link the source.
Real papers from PubMed and clinical databases — not blog posts. 235+ studies across the range and counting.
A human trial outranks a mouse study, which outranks a lab dish. The grade reflects that hierarchy — honestly.
Every use links to the actual study. If we found nothing, we grade it None — and say so out loud.
