Single oils and blends with a batch test you can read, sold without medical claims.
How we rank essential oils
- Purity 35%
- Batch testing 25%
- Sourcing 15%
- Trust 10%
- Value 15%
Why, and what each one means
We rank lavender oils on purity (35%), batch testing (25%), sourcing (15%), price per milliliter (15%) and trust (10%). A GC-MS lot report shows an oil is lavender, but a standard profile can miss clever blends (2021 study (opens in a new tab)), and lavender oil sensitizes skin (opens in a new tab) once it oxidizes. So lot reports, organic sourcing and plain safety copy score highest. Read our safety guide before using any oil.
- Purity 35%
- One plant, named by its Latin name and the part distilled, with nothing added: no carrier oil, synthetic or “nature-identical” components.
- Batch testing 25%
- GC-MS results for the batch you buy, published by lot number. Independent tests count for more than the maker’s.
- Sourcing 15%
- Country of origin named, organic or wild-harvested, and a distiller the maker can name.
- Trust 10%
- Highest when the maker names everything, answers questions, and has no recalls, warning letters, Prop 65 notices or lawsuits over safety or labeling. Points come off for unresolved problems and for paid promoters it does not disclose.
- Value 15%
- Price per milliliter against the others here that pass.
Each product scores every one from 1 to 5, and its rating is the weighted average. We list only products rated 3 or above that break none of our rules.
We avoid
- “Therapeutic grade”, “certified pure” and other seals the seller gives itself. No outside body grades essential oils.
- Instructions to take oils by mouth or put them on skin undiluted.
- Immune, antiviral or disease claims.
